Headlines

RedisJSON 2.6 introduces support for RESP3 and new commands.

What's new in 2.6

  • Introduce JSON.MERGE in compliance with RFC 7396, supporting:

    • Creating new attributes on an existing JSON document

    • Updating and replacing values in parent and child attributes

    • Deleting existing attributes (by setting the value to null)

    • Array update - replacing an entire array with the new value

  • Introduce JSON.MSET, supporting atomic multiple sets for keys in the same hash slot

  • New FORMAT argument in JSON.ARRPOP and JSON.GET to retrieve the results as JSON strings or RESP3 hierarchical structures (RESP3 only)

  • JSON.RESP is now regarded as deprecated

  • Legacy paths (paths that don't start with either $. or $[ or equal to $), except those starting with ., are now deprecated

Note:

  • The version inside Redis will be 2.6.4 in semantic versioning. Since the version of a module in Redis is numeric, we could not add a GA flag.

  • Minimal Redis version: 7.2
