v.4.32.0

Improvements:

1. [LUNA-8216] Added support for JSON filtering with new operators and data type for meta field in events and event field in general events.

   New operators:

   • contains - checks if all elements of the provided value are contained in the event field

   • ncontains - negation of contains operator

   • overlaps - checks if at least one element from the array overlaps with the event field

   • noverlaps - negation of overlaps operator

   New data type:

   • json - allows filtering by JSON objects and arrays (values must be URL-encoded JSON strings)

   Extended operators:

   The :json type is now supported for existing operators: eq, neq, in, nin - enabling exact match for JSON objects and arrays, and containment checks.

   Affected endpoints:

   • get events

   • get general events

   • get events stats

   • get general events stats

   Documentation:

   For optimal performance with JSON operators, GIN indexes are recommended. See indexing guidelines:

   • User defined data (meta field) - Index building

   • General events (event field) - Index building
