Configuration¶

The service allowed two variant of configuration:

use the Configurator service

use the configuration file

The service reads settings from the configuration file by default.

You can specify the –luna-config option for pulling settings from the Configurator service, see configurator.

Auto reload configuration¶

The service supports an auto-reload of configurations. You can enable this feature by specifying a config-reload option in the command line. The service periodically checks new settings. If current settings and new pulled settings are the same the service will not perform any actions. You can specify the check period in the pulling-time command line argument (10 seconds by default).

If a configuration fetching has failed, the service will work without applying any changes to the existing configurations.

If check connections with the new configuration have failed, the service will retry pulling new configuration after pulling-time seconds. The service will shut down after 10 failed attempts.

Warning

Service can work incorrectly while the new settings are being applied. It is strongly recommended not to send requests to the service when you change important settings (database credentials, work plugins list, and others).

During configuration reload any existing HTTP connections to the service will be closed.

If descriptor caching enabled and critical descriptor caching settings updated, the cache will be dropped. The critical descriptor caching settings are:

matcher thread count

faces database settings

default face descriptor version

In other cases, the cache will not be dropped, unless critical errors have occurred during reinitialization.

Configuration file for administrator¶

Warning

The Platform limits parameter enables you to configure various limits:

References and candidates limits in the request.
Limit of the candidates returned in the response for each reference.
Limit for the number of items for some filters.

Matching using CORE Indexed Matcher¶

RabbitMQ is used as a message queue for CORE Indexed Matcher. The RabbitMQ parameters must be specified in the [QUEUE_SETTINGS] section.

The INDEXED_MATCHER parameter must be set to “1” for the CORE Indexed Matcher utilization.

Use the [LUNA_MATCHER_CLUSTERS.*] section to configure usage of the CORE Indexed Matcher. Set the number of cluster instead of “*”

You must specify the following parameters:

CLUSTER_TYPE - the type of the used matcher: only core-indexed-matcher available at the moment;
ROUTING_KEY - the routing key set for the Matcher in RabbitMQ;
RABBIT_EXCHANGE - the exchange set for the Matcher in RabbitMQ.
