Headlines

RedisJSON 2.6 introduces support for RESP3 and new commands.

What's new in 2.6

• Introduce [JSON.MERGE]({{< relref "commands/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]({{< relref "commands/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 {{</note>}}
