Configuration parameters of services#

Configurator configuration#

The section describes the Configurator service parameters.

The Configurator service itself is configured using the configuration file './example-docker/luna_configurator/configs/'.

LUNA_CONFIGURATOR_DB section#

In this section, the settings for connecting to the database of the service Configurator are set.

db_type#

The parameter sets the type of database used. The following types are available:

"postgres" — PostgreSQL database type
"oracle" — Oracle database type

Setting format: string.

Default value: postgres.

db_host#

The parameter sets the IP address of the server with the database.

Setting format: string.

Default value: 127.0.0.1.

db_port#

The parameter sets database listener port.

The default port for "postgres" type is 5432

The default port for "oracle" type is 1521

Setting format: string.

Default value: 5432.

db_user#

The parameter sets the database username.

Setting format: string.

Default value: luna.

db_password#

The parameter sets the database password.

Setting format: string.

Default value: luna.

db_name#

The parameter sets the database name for "postgres" and the name of the SID for "oracle" type to connect to.

Setting format: string.

Default value: luna_configurator.

connection_pool_size#

The parameter sets the database connection pool size. The actual number of connections may be greater than the value of this setting by 1.

If necessary, in the "max_connections" configuration of the PostgreSQL configuration file, you can set the maximum number of simultaneous connections to the database server. See the section "Advanced PostrgeSQL setting" for more details.

Setting format: string.

Default value: 10.

dsn#

The parameter sets the DSN connection string for connecting to the database.

DSN is a connection string that identifies and points to the data source (database) to which you want to establish a connection.

Settings such as multiple hosts, authentication data, port, and other parameters can be set in the DSN string.

The settings depend on the type of database. Multiple hosts are supported only with PostgreSQL.

By default, the "dsn" parameter is not displayed in the "Settings" tab in the Configurator. You can check the list of all available parameters for a section on the "Limitations" tab.

Below is an example of specifying the "dsn" parameter:

{
"dsn": "luna:luna@postgres01:5432,postgres02:5432/luna_configurator?some_option=some_value"
"db_settings": {
"connection_pool_size": 5
}
}

Here:

"luna:luna" — Username and password for connecting to PostgreSQL.
"@postgres01:5432,postgres02:5432" — Comma-separated list of hosts and ports. This means that the service will try to connect to the first host ("postgres01") on port 5432. If this fails, it will try to connect to the second host ("postgres02") also on port 5432.
"/luna_configurator" — Database name.
"?some_option=some_value" — Optional parameters for connection.

If necessary, you can combine the DSN string and the classic settings, but the DSN string is a higher priority. You can partially fill in the DSN string (for example, "postgres 01,postgres02/luna_configurator"), and then the missing parameters will be filled in from the values of the parameters "db_host", "db_port", "db_name", "db_user" and "db_password".

At startup, the service will create a pool of connections to one of the available DSN hosts. In case of problems with establishing a connection after several unsuccessful attempts, the service will again try to set up a connection pool to any of the available DSN hosts.

Setting format: string.

Default value: 10.

dsn#

The parameter sets the DSN connection string for connecting to the database.

DSN is a connection string that identifies and points to the data source (database) to which you want to establish a connection.

Settings such as multiple hosts, authentication data, port, and other parameters can be set in the DSN string.

The settings depend on the type of database. Multiple hosts are supported only with PostgreSQL.

By default, the "dsn" parameter is not displayed in the "Settings" tab in the Configurator. You can check the list of all available parameters for a section on the "Limitations" tab.

Below is an example of specifying the "dsn" parameter:

{
"dsn": "luna:luna@postgres01:5432,postgres02:5432/luna_tasks?some_option=some_value"
"db_settings": {
"connection_pool_size": 5
}
}

Here:

"luna:luna" — Username and password for connecting to PostgreSQL.
"@postgres01:5432,postgres02:5432" — Comma-separated list of hosts and ports. This means that the service will try to connect to the first host ("postgres01") on port 5432. If this fails, it will try to connect to the second host ("postgres02") also on port 5432.
"/luna_tasks" — Database name.
"?some_option=some_value" — Optional parameters for connection.

If necessary, you can combine the DSN string and the classic settings, but the DSN string is a higher priority. You can partially fill in the DSN string (for example, "postgres 01,postgres02/luna_tasks"), and then the missing parameters will be filled in from the values of the parameters "db_host", "db_port", "db_name", "db_user" and "db_password".

At startup, the service will create a pool of connections to one of the available DSN hosts. In case of problems with establishing a connection after several unsuccessful attempts, the service will again try to set up a connection pool to any of the available DSN hosts.

Setting format: string.

Default value: 10.

dsn#

The parameter sets the DSN connection string for connecting to the database.

DSN is a connection string that identifies and points to the data source (database) to which you want to establish a connection.

Settings such as multiple hosts, authentication data, port, and other parameters can be set in the DSN string.

The settings depend on the type of database. Multiple hosts are supported only with PostgreSQL.

By default, the "dsn" parameter is not displayed in the "Settings" tab in the Configurator. You can check the list of all available parameters for a section on the "Limitations" tab.

Below is an example of specifying the "dsn" parameter:

{
"dsn": "luna:luna@postgres01:5432,postgres02:5432/luna_events?some_option=some_value"
"db_settings": {
"connection_pool_size": 5
}
}

Here:

"luna:luna" — Username and password for connecting to PostgreSQL.
"@postgres01:5432,postgres02:5432" — Comma-separated list of hosts and ports. This means that the service will try to connect to the first host ("postgres01") on port 5432. If this fails, it will try to connect to the second host ("postgres02") also on port 5432.
"/luna_events" — Database name.
"?some_option=some_value" — Optional parameters for connection.

If necessary, you can combine the DSN string and the classic settings, but the DSN string is a higher priority. You can partially fill in the DSN string (for example, "postgres 01,postgres02/luna_events"), and then the missing parameters will be filled in from the values of the parameters "db_host", "db_port", "db_name", "db_user" and "db_password".

At startup, the service will create a pool of connections to one of the available DSN hosts. In case of problems with establishing a connection after several unsuccessful attempts, the service will again try to set up a connection pool to any of the available DSN hosts.

}
}

Here:

"luna:luna" — Username and password for connecting to PostgreSQL.
"@postgres01:5432,postgres02:5432" — Comma-separated list of hosts and ports. This means that the service will try to connect to the first host ("postgres01") on port 5432. If this fails, it will try to connect to the second host ("postgres02") also on port 5432.

Setting format: string.

Default value: 10.

dsn#

The parameter sets the DSN connection string for connecting to the database.

DSN is a connection string that identifies and points to the data source (database) to which you want to establish a connection.

Settings such as multiple hosts, authentication data, port, and other parameters can be set in the DSN string.

The settings depend on the type of database. Multiple hosts are supported only with PostgreSQL.

By default, the "dsn" parameter is not displayed in the "Settings" tab in the Configurator. You can check the list of all available parameters for a section on the "Limitations" tab.

Below is an example of specifying the "dsn" parameter:

{
"dsn": "luna:luna@postgres01:5432,postgres02:5432/luna_events?some_option=some_value"
"db_settings": {
"connection_pool_size": 5
}
}

Here:

"luna:luna" — Username and password for connecting to PostgreSQL.
"@postgres01:5432,postgres02:5432" — Comma-separated list of hosts and ports. This means that the service will try to connect to the first host ("postgres01") on port 5432. If this fails, it will try to connect to the second host ("postgres02") also on port 5432.
"/luna_events" — Database name.
"?some_option=some_value" — Optional parameters for connection.

If necessary, you can combine the DSN string and the classic settings, but the DSN string is a higher priority. You can partially fill in the DSN string (for example, "postgres 01,postgres02/luna_events"), and then the missing parameters will be filled in from the values of the parameters "db_host", "db_port", "db_name", "db_user" and "db_password".

At startup, the service will create a pool of connections to one of the available DSN hosts. In case of problems with establishing a connection after several unsuccessful attempts, the service will again try to set up a connection pool to any of the available DSN hosts.

LUNA_PYTHON_MATCHER_ADDRESS section#

These settings are useful for balancing performance and resource usage.

Parameters from the "match" subsection define restrictions associated with matching operations.

Parameters from the "cross_match" subsection define restrictions associated with cross-matching operations (see "Cross-matching" task description).

match > array_filter_limit#

The parameter sets the maximum number of objects (maximum array size) specified in the "face_ids", "event_ids" and "attribute_ids" filters.

Setting format: integer.

Default value: 1000.

match > reference_limit#

The parameter sets the maximum number of references (maximum array size) that can be specified in a matching request.

You must select the value of this parameter in accordance with your business cases, because it consumes system resources significantly. For example, you should not use the default value of "30" if you only need to work with three references. See "Resource optimization" for more tips on optimizing resources.

Setting format: integer.

Default value: 30.

match > candidate_limit#

The parameter sets the maximum number of candidates (maximum array size) that can be specified in a matching request.

You must select the value of this parameter in accordance with your business cases, because it consumes system resources significantly. For example, you should not use the default value of "30" if you only need to work with three candidates. See "Resource optimization" for more tips on optimizing resources.

Setting format: integer.

Default value: 30.

match > result_candidate_limit#

The parameter sets the maximum number of matching results (maximum array size) for the list of candidates returned in the matching request response.

In the matching request body, you can also limit the number of candidates returned in the response using the "limit" parameter, but the "result_candidate_limit" parameter takes precedence. This means that if the value "result_candidate_limit" = 4 and "limit" = 6, an error with code "31007" will be returned.

Setting format: integer.

Default value: 100.

cross_match > short_array_filter_limit#

The parameter sets the maximum number of objects (maximum array size) specified in all filters, except for the filters "face_ids", "event_ids" and "attribute_ids" in the Cross-matching task.

For example, the maximum array size for the filters "sources", "tags", "cities", etc. In the OpenAPI specification, such filters are marked with the example [ 1 .. 1000 ] items.

Setting format: integer.

Default value: 1000.

cross_match > array_filter_limit#

The parameter sets the maximum number of objects (maximum array size) specified in the filters "face_ids", "event_ids" and "attribute_ids" in the Cross-matching task.

In the OpenAPI specification, such filters are marked with the example [ 1 .. 20000 ] items.

Setting format: integer.

Default value: 20000.

cross_match > result_candidate_limit#

The parameter sets the maximum number of matching results (maximum array size) for the list of candidates returned in the response of the request to get the result of the Cross-matching task.

In the matching request body, you can also limit the number of candidates returned in the response using the "limit" parameter, but the "result_candidate_limit" parameter takes precedence. This means that if the value "result_candidate_limit" = 4 and "limit" = 6, an error with code "31007" will be returned.

Setting format: integer.

Default value: 20000.

cross_match > general_limit#

The parameter sets a general limit on the number of cross-matchings. It is applied to the product of the number of candidates and references that participate in the matching operation, taking into account filters. If the product exceeds the value "general_limit", the request will fail.

For example, if the value of "general_limit" is "20", the number of candidate faces in the array "face_ids" is "7", the number of reference faces in the array "face_ids" is "5" and all other filters do not reduce the actual number of candidate faces, the cross-matching request will not be executed, because the total number of cross-matchings will be equal to "35" (5 x 7). If some filter reduces the total number of candidate faces by "3", then the request will be executed successfully, because the total number of cross-matchings will be equal to "20" (5 x (7 - 3)).

Setting format: integer.

Default value: 100000.

These settings are useful for balancing performance and resource usage.

Parameters from the "match" subsection define restrictions associated with matching operations.

Parameters from the "cross_match" subsection define restrictions associated with cross-matching operations (see "Cross-matching" task description).

match > array_filter_limit#

The parameter sets the maximum number of objects (maximum array size) specified in the "face_ids", "event_ids" and "attribute_ids" filters.

Setting format: integer.

Default value: 1000.

match > reference_limit#

The parameter sets the maximum number of references (maximum array size) that can be specified in a matching request.

You must select the value of this parameter in accordance with your business cases, because it consumes system resources significantly. For example, you should not use the default value of "30" if you only need to work with three references. See "Resource optimization" for more tips on optimizing resources.

Setting format: integer.

Default value: 30.

match > candidate_limit#

The parameter sets the maximum number of candidates (maximum array size) that can be specified in a matching request.

You must select the value of this parameter in accordance with your business cases, because it consumes system resources significantly. For example, you should not use the default value of "30" if you only need to work with three candidates. See "Resource optimization" for more tips on optimizing resources.

Setting format: integer.

Default value: 30.

match > result_candidate_limit#

The parameter sets the maximum number of matching results (maximum array size) for the list of candidates returned in the matching request response.

In the matching request body, you can also limit the number of candidates returned in the response using the "limit" parameter, but the "result_candidate_limit" parameter takes precedence. This means that if the value "result_candidate_limit" = 4 and "limit" = 6, an error with code "31007" will be returned.

Setting format: integer.

Default value: 100.

cross_match > short_array_filter_limit#

The parameter sets the maximum number of objects (maximum array size) specified in all filters, except for the filters "face_ids", "event_ids" and "attribute_ids" in the Cross-matching task.

For example, the maximum array size for the filters "sources", "tags", "cities", etc. In the OpenAPI specification, such filters are marked with the example [ 1 .. 1000 ] items.

Setting format: integer.

Default value: 1000.

cross_match > array_filter_limit#

The parameter sets the maximum number of objects (maximum array size) specified in the filters "face_ids", "event_ids" and "attribute_ids" in the Cross-matching task.

In the OpenAPI specification, such filters are marked with the example [ 1 .. 20000 ] items.

Setting format: integer.

Default value: 20000.

cross_match > result_candidate_limit#

The parameter sets the maximum number of matching results (maximum array size) for the list of candidates returned in the response of the request to get the result of the Cross-matching task.

In the matching request body, you can also limit the number of candidates returned in the response using the "limit" parameter, but the "result_candidate_limit" parameter takes precedence. This means that if the value "result_candidate_limit" = 4 and "limit" = 6, an error with code "31007" will be returned.

Setting format: integer.

Default value: 20000.

cross_match > general_limit#

The parameter sets a general limit on the number of cross-matchings. It is applied to the product of the number of candidates and references that participate in the matching operation, taking into account filters. If the product exceeds the value "general_limit", the request will fail.

For example, if the value of "general_limit" is "20", the number of candidate faces in the array "face_ids" is "7", the number of reference faces in the array "face_ids" is "5" and all other filters do not reduce the actual number of candidate faces, the cross-matching request will not be executed, because the total number of cross-matchings will be equal to "35" (5 x 7). If some filter reduces the total number of candidate faces by "3", then the request will be executed successfully, because the total number of cross-matchings will be equal to "20" (5 x (7 - 3)).

Setting format: integer.

Default value: 100000.

LUNA_PYTHON_MATCHER_DB section#

In this section, the settings for connecting to the database of the service Python-Matcher are set.

Setting format: string.

Default value: 10.

dsn#

The parameter sets the DSN connection string for connecting to the database.

DSN is a connection string that identifies and points to the data source (database) to which you want to establish a connection.

Settings such as multiple hosts, authentication data, port, and other parameters can be set in the DSN string.

The settings depend on the type of database. Multiple hosts are supported only with PostgreSQL.

By default, the "dsn" parameter is not displayed in the "Settings" tab in the Configurator. You can check the list of all available parameters for a section on the "Limitations" tab.

Below is an example of specifying the "dsn" parameter:

}
}

Here:

"luna:luna" — Username and password for connecting to PostgreSQL.
"@postgres01:5432,postgres02:5432" — Comma-separated list of hosts and ports. This means that the service will try to connect to the first host ("postgres01") on port 5432. If this fails, it will try to connect to the second host ("postgres02") also on port 5432.
"/luna_python_matcher" — Database name.
"?some_option=some_value" — Optional parameters for connection.

If necessary, you can combine the DSN string and the classic settings, but the DSN string is a higher priority. You can partially fill in the DSN string (for example, "postgres 01,postgres02/luna_python_matcher"), and then the missing parameters will be filled in from the values of the parameters "db_host", "db_port", "db_name", "db_user" and "db_password".

At startup, the service will create a pool of connections to one of the available DSN hosts. In case of problems with establishing a connection after several unsuccessful attempts, the service will again try to set up a connection pool to any of the available DSN hosts.

"@postgres01:5432,postgres02:5432" — Comma-separated list of hosts and ports. This means that the service will try to connect to the first host ("postgres01") on port 5432. If this fails, it will try to connect to the second host ("postgres02") also on port 5432.
"/luna_handlers" — Database name.
"?some_option=some_value" — Optional parameters for connection.

If necessary, you can combine the DSN string and the classic settings, but the DSN string is a higher priority. You can partially fill in the DSN string (for example, "postgres 01,postgres02/luna_handlers"), and then the missing parameters will be filled in from the values of the parameters "db_host", "db_port", "db_name", "db_user" and "db_password".

At startup, the service will create a pool of connections to one of the available DSN hosts. In case of problems with establishing a connection after several unsuccessful attempts, the service will again try to set up a connection pool to any of the available DSN hosts.

FACE_QUALITY_SETTINGS section#

This section specifies the thresholds at which LUNA PLATFORM will consider that the check has passed.

There are two types of standard thresholds in this section of parameters:

Thresholds from the "threshold" field, which determine at what value LUNA PLATFORM will consider the check to have passed. These thresholds are similar to the thresholds in the "face_quality" section of the corresponding requests. Setting thresholds in requests overrides the standard thresholds set in the "FACE_QUALITY_DEFAULT_THRESHOLDS" section.
Thresholds from the "config" field that determine how to interpret the response of Natural Light, Fish Eye, Color Type and Red Eyes estimators. Previously, these thresholds were not available.

An example of configuring thresholds for a Red Eyes estimator:

"red_eye": {
     "threshold": 0,
     "config": {
          "estimator": {
               "threshold": {
               "min": 0.5
}    }    }    }

Here:

"threshold" field defines the value "0" or "1" at which LUNA PLATFORM will consider the check to have passed. Similar to the "threshold" parameter in "face_quality" requests.
"config" > "estimator" > "threshold" section defines the response of the Red Eyes estimator from "0" to "1".

See "Image check" for details.

Important: These thresholds are default. Setting thresholds in the "face_quality" parameter group overrides the value of these thresholds.

Setting format: string.

Default value: 10.

dsn#

The parameter sets the DSN connection string for connecting to the database.

DSN is a connection string that identifies and points to the data source (database) to which you want to establish a connection.

Settings such as multiple hosts, authentication data, port, and other parameters can be set in the DSN string.

The settings depend on the type of database. Multiple hosts are supported only with PostgreSQL.

By default, the "dsn" parameter is not displayed in the "Settings" tab in the Configurator. You can check the list of all available parameters for a section on the "Limitations" tab.

Below is an example of specifying the "dsn" parameter:

{
"dsn": "luna:luna@postgres01:5432,postgres02:5432/luna_video_manager?some_option=some_value"
"db_settings": {
"connection_pool_size": 5
}
}

Here:

"luna:luna" — Username and password for connecting to PostgreSQL.
"@postgres01:5432,postgres02:5432" — Comma-separated list of hosts and ports. This means that the service will try to connect to the first host ("postgres01") on port 5432. If this fails, it will try to connect to the second host ("postgres02") also on port 5432.
"/luna_video_manager" — Database name.
"?some_option=some_value" — Optional parameters for connection.

If necessary, you can combine the DSN string and the classic settings, but the DSN string is a higher priority. You can partially fill in the DSN string (for example, "postgres 01,postgres02/luna_video_manager"), and then the missing parameters will be filled in from the values of the parameters "db_host", "db_port", "db_name", "db_user" and "db_password".

At startup, the service will create a pool of connections to one of the available DSN hosts. In case of problems with establishing a connection after several unsuccessful attempts, the service will again try to set up a connection pool to any of the available DSN hosts.

"postgres" — PostgreSQL database type
"oracle" — Oracle database type

Setting format: string.

Default value: postgres.

db_host#

The parameter sets the IP address of the server with the database.

Setting format: string.

Default value: 127.0.0.1.

db_port#

The parameter sets database listener port.

The default port for "postgres" type is 5432

The default port for "oracle" type is 1521

Setting format: string.

Default value: 5432.

db_user#

The parameter sets the database username.

Setting format: string.

Default value: luna.

db_password#

The parameter sets the database password.

Setting format: string.

Default value: luna.

db_name#

The parameter sets the database name for "postgres" and the name of the SID for "oracle" type to connect to.

Setting format: string.

Default value: luna_lambda.

connection_pool_size#

The parameter sets the database connection pool size. The actual number of connections may be greater than the value of this setting by 1.

If necessary, in the "max_connections" configuration of the PostgreSQL configuration file, you can set the maximum number of simultaneous connections to the database server. See the section "Advanced PostrgeSQL setting" for more details.

Setting format: string.

Default value: 10.

dsn#

The parameter sets the DSN connection string for connecting to the database.

DSN is a connection string that identifies and points to the data source (database) to which you want to establish a connection.

Settings such as multiple hosts, authentication data, port, and other parameters can be set in the DSN string.

The settings depend on the type of database. Multiple hosts are supported only with PostgreSQL.

By default, the "dsn" parameter is not displayed in the "Settings" tab in the Configurator. You can check the list of all available parameters for a section on the "Limitations" tab.

Below is an example of specifying the "dsn" parameter:

{
"dsn": "luna:luna@postgres01:5432,postgres02:5432/luna_lambda?some_option=some_value"
"db_settings": {
"connection_pool_size": 5
}
}

Here:

"luna:luna" — Username and password for connecting to PostgreSQL.
"@postgres01:5432,postgres02:5432" — Comma-separated list of hosts and ports. This means that the service will try to connect to the first host ("postgres01") on port 5432. If this fails, it will try to connect to the second host ("postgres02") also on port 5432.
"/luna_lambda" — Database name.
"?some_option=some_value" — Optional parameters for connection.

If necessary, you can combine the DSN string and the classic settings, but the DSN string is a higher priority. You can partially fill in the DSN string (for example, "postgres 01,postgres02/luna_lambda"), and then the missing parameters will be filled in from the values of the parameters "db_host", "db_port", "db_name", "db_user" and "db_password".

At startup, the service will create a pool of connections to one of the available DSN hosts. In case of problems with establishing a connection after several unsuccessful attempts, the service will again try to set up a connection pool to any of the available DSN hosts.

Tasks-lambda configuration#

This section describes the parameters for each lambda tasks unit. Most of the settings are similar to the settings described in the "Tasks service configuration" section. The individual settings are described below.

You can configure the service using the Configurator service.

LUNA_LAMBDA_TASKS_UNIT_LOGGER section#

This section sets the logging settings for the logging.

log_level#

The parameter sets the level of debug printing, by priority: "ERROR", "WARNING", "INFO", "DEBUG".

Setting format: string.

Default value: INFO.

log_time#

The parameter sets the time format used in log entries. The following values are available:
