Highlights

RedisJSON 2.4 contains several low-level API changes in order to support the multi-value indexing and querying support that comes with RediSearch 2.6. RediSearch 2.6 comes with multi-value indexing and querying of attributes for any attribute type (Text, Tag, Numeric, Geo and Vector) defined by a JSONPath leading to an array or to multiple scalar values.

What's new in 2.4

• Features:

  • #848 Add JSONPath filter the regexp match operator (MOD-4432)
  • #861 Support legacy JSONPath with the dollar sign $ (MOD-4436)

• Performance enhancements:

  • #699 A new JSONPath library which enhances the performance of parsing any JSONPath expression in RedisJSON.

• Changing behaviour:

  • #699 Floating point numbers which become round numbers due to some operation, such as JSON.NUMINCRBY, will now return as a floating point with a trailing .0, e.g., instead of just 42, now 42.0 will be returned.

• Bugs fixes (since 2.4-RC1/ v2.4.0):

  • #850 Allow repetition of filter relation instead of optional (MOD-4431)
