Redis Stack 7.2.0-v0 (August 2023)

This is a GA release of Redis Stack version 7.2.

Headlines:

Redis server 7.2 introduces significant memory and speed optimizations for lists, sets, and sorted sets, several improvements, including encoding improvements for sets and lists, stream consumer group improvements, and improved durability. Search and Query brings the frequently asked Geo polygons queries for basic shapes and improved query performance on sorting in different scenarios. JSON introduces two new commands: JSON.MERGE and JSON.MSET for more efficient data manipulation. Preview of triggers and functions that allows developers to run JavaScript functions inside the Redis process. Lastly, 7.2 adds the option to use the new protocol RESP3 improving the response format for all commands.

Redis server: Redis server 7.2 brings performance and resource utilization improvements, including significant memory and speed optimizations for lists, sets, and sorted sets. This new version adds a new WITHSCORE command argument for ZRANK and ZREVRANK, new commands, such as CLIENT NO-TOUCH for clients to run commands without affecting LRU/LFU of keys, and more. Redis 7.2 brings behavior changes by introducing a new format (version 11) for RDB files, which is incompatible with older versions, changing module API, and other changes.

Search and Query: This new major version introduces the frequently asked Geo Polygon Search. Adding the GEOSHAPE field type that supports polygon shapes using the WKT notation. In addition to the existing GEO for geo range queries, now an alias for GEOPOINT, we add GEOSHAPE with the support for POLYGON and POINT as new shapes formats and polygons operations.

In addition, 7.2 brings improvements in performance for SORT BY operations using FT.SEARCH and FT.AGGREGATE, and the new FORMAT for better readability and future support for better error handling responses on FT.SEARCH and FT.AGGREGATE in RESP3 only.

JSON: JSON introduces two new commands:

  • JSON.MERGE merges a given JSON value into matching paths so that the JSON values at the matching paths are updated, deleted, or expanded.
  • JSON.MSET sets or updates one or more JSON values according to specified key-path-value triplets.

Graph:

Graph capabilities are no longer included in Redis Stack. See the RedisGraph End-of-Life Announcement.

[!WARNING]
If you are using graph capabilities with an older version of Redis Stack - please don't upgrade.

Triggers and functions preview: Triggers and functions is part of Redis Stack 7.2 as public preview, any feedback is highly appreciated.

Triggers and functions provides support for running JavaScript functions inside the Redis process. These functions can be executed on-demand, by an event-driven trigger, or by a stream processing trigger. Triggers and functions empowers developers to build and maintain real-time applications by moving logic closer to the data, ensuring a lower latency whilst delivering the best developer experience.

Try it out with the triggers and functions quick start.

Redis Stack 7.2.0-rc2 (July 2023)

This is the third release of Redis Stack version 7.2.0.

Update urgency: SECURITY: there are security fixes in the release.

Headlines:

This version contains security improvements for the Redis server.

Details:

Features

  • Redis:
    • #10362 Make SENTINEL CONFIG [SET|GET] variadic
    • #12133 Add a new loglevel "nothing" to disable logging
    • #9564 Add cluster-announce-human-nodename - a unique identifier for a node that is be used in logs for debugging

Improvements

  • Redis:
    • (CVE-2022-24834) A specially crafted Lua script executing in Redis can trigger a heap overflow in the cjson and cmsgpack libraries, and result in heap corruption and potentially remote code execution. The problem exists in all versions of Redis with Lua scripting support, starting from 2.6, and affects only authenticated and authorized users.
    • (CVE-2023-36824) Extracting key names from a command and a list of arguments may, in some cases, trigger a heap overflow and result in reading random heap memory, heap corruption and potentially remote code execution. Specifically: using COMMAND GETKEYS* and validation of key names in ACL rules.
    • #12269 Allow CLUSTER SLOTS / SHARDS commands during loading
    • #12233 Support TLS service when "tls-cluster" is not enabled and persist both plain and TLS port in nodes.conf
    • #12320 Update SPOP and RESTORE commands to replicate unlink commands to replicas when the server is configured to use async server deletes
    • #12229 Try lazyfree the temporary zset in ZUNION / ZINTER / ZDIFF
    • #12298 Optimize PSUBSCRIBE and PUNSUBSCRIBE from O(N*M) to O(N)
    • #12209 Optimize SCAN, SSCAN, HSCAN, ZSCAN commands
    • #12315 Set Jemalloc --disable-cache-oblivious to reduce memory overhead
    • #12229 Optimize ZINTERCARD to avoid create a temporary zset
    • #12205 Optimize HRANDFIELD and ZRANDMEMBER listpack encoded ()
    • #12155, #12082, #11626, #11944, #12316, #12250, #12177, #12185 Numerous other optimizations
    • #12254 redis-cli: Handle RESP3 double responses that contain a NaN
    • #11834 redis-cli: Support URIs with IPv6

Changed Behavior

  • Redis:
    • #10536, #12166 Cluster SHARD IDs are no longer visible in the cluster nodes output
    • #12326 When calling PUBLISH with a RESP3 client that's also subscribed to the same channel, the order is changed and the reply is sent before the published message
    • #12321 Align semantics of the new (v7.2 RC2) RM_ReplyWithErrorFormat with RM_ReplyWithError. This is a breaking change that affects the generated error code
    • #12304 Forbid RM_AddPostNotificationJob on loading and on read-only replicas
    • #12219 Add ability for module command filter to know which client is being handled

Bug Fixes

  • Redis:
    • #12326 Fix broken protocol when PUBLISH is used inside MULTI when the RESP3 publishing client is also subscribed for the channel
    • #12220 Fix WAIT to be effective after a blocked module command being unblocked
    • #12276 Re-enable downscale rehashing while there is a fork child
    • #12276 Fix possible hang in HRANDFIELD, SRANDMEMBER, ZRANDMEMBER when used with <count>
    • #12276 Improve fairness issue in RANDOMKEY, HRANDFIELD, SRANDMEMBER, ZRANDMEMBER, SPOP, and eviction
    • #12344 Cluster: fix a race condition where a slot migration may revert on a subsequent failover or node joining
    • #12301Fix XREADGROUP BLOCK with ">" from hanging
    • #12247Fix assertion when a blocked command is rejected when re-processed
    • #12342Fix use after free on a blocking RM_Call

Redis Stack 7.2.0-rc2 (June 2023)

This is the second release of Redis Stack version 7.2.0.

Headlines:

This version contains a new capability - Triggers and Functions, improvements to the Search and Query capability, and improvements to the JSON, time series and probabilistic data structures. It also includes the latest version of RedisInsight.

The new Search and Query version introduces new and frequently asked Geo Polygon Search. Adding the GEOSHAPE field type that supports polygon shapes using WKT notation. Besides the current GEO (alias for GEOPOINT) used already geo range queries, we add the support for POLYGON as new shapes. In addition, it brings improvements in performance for SORT BY operations using FT.SEARCH and FT.AGGREGATE.

This release includes a new capability - Triggers and Functions that brings the ability to execute and trigger business logic inside Redis using JavaScript (JS). Detailed documentation and examples can be found in this GitHub repository. The Triggers and Functions commands are aligned with the Redis Functions command. The API is not yet final and might change based on feedback. Any feedback is highly appreciated.

Details:

Features

  • Search and Query:

    • #3553 Introduce support for Geo-polygon shapes and queries
      • #3476, #3660 Adding GEOSHAPE field type to map polygons in the SCHEMA on FT.CREATE.
      • Support for polygons POLYGON using WKT notation, for example POLYGON((x1 y1, x2 y2, ...)).
      • #3556 Adjust the query syntax on FT.SEARCH for Polygons using the predicate @geom:[OPERATOR $poly] and defining polygon in WKT format as PARAMS 2 poly "POLYGON((10 20, ...))" using DIALECT 3.
      • Initially WITHIN and CONTAINS operators with GEOSHAPES for now.
      • #3645 Support multiple coordinate systems cartesian (X,Y) and geographic (lon, lat). Geographic coordinate system using spherical indexing as default (SPHERICAL).
    • #3046 Introduce performance optimization for sorting operations on FT.SEARCH and FT.AGGREGATE as default on DIALECT 4. It will improve performance in 4 different scenarios, listed below:
      • Skip Sorter - applied when there is no sort of any kind. The query can return once it reaches the LIMIT requested results.
      • Partial Range - applied when there is a SORTBY a numeric field, with no filter or filter by the same numeric field, the query iterate on a range large enough to satisfy the LIMIT requested results.
      • Hybrid - applied when there is a SORTBY a numeric field in addition to another non-numeric filter. Some results will get filtered, and the initial range may not be large enough. The iterator then is rewinded with the following ranges, and an additional iteration takes place to collect LIMIT requested results.
      • No optimization - If there is a sort by score or by non-numeric field, there is no other option but to retrieve all results and compare their values.
      • #3651 Add WITHCOUNT argument that allow return accurate counts for the query results with sorting. This operation processes all results in order to get accurate count, being less performant than the optimised option (default behaviour on DIALECT 4).

  • JSON:

    • #916 Introduce the new 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 (giving null as value)
      • Array update - replacing an entire array with the new value.
    • #944 Introduce JSON.MSET, supporting atomic multiple sets for keys in the same hash slot.

  • Triggers and Functions:

    • #875 The api_version was added to the library prologue indicating the minimum required API version. Indicating the library works on the specified API version and later minor versions. #896 Additional optional callback on a KeySpace trigger that can perform read operations exactly when the notification happens.
    • #910 The JavaScript API is updated to be inline with JavaScript best practices. Registrations of functions and triggers is done with mandatory arguments and a single optional object.
    • #935 Ability to load an RDB from a Redis Server with the RedisGears module loaded but NOT used into a Redis Server without the RedisGears module.
    • Updated commands:
      • #910 TFUNCTION and TFCALL is used instead of RG.FUNCTION and RG.FCALL.
      • #939 The commands are updated to match the Redis Functions commands. TFCALL combines the library and function in a single argument with '.' separated. Example: TFCALL <library_name>.<function_name>.
      • #900 rated the ability to run functions as a coroutine in TFCALLASYNC. Clients rely on TFCALL to never block shared connections so other commands are not delayed on such connections.

Improvements

  • Search and Query:

    • #3641 Indexing sanitizing trigger in heavily data updates scenario.
    • #3614 Several improvements in the aggregations execution pipeline.

  • Triggers and Functions:

    • #906 Limit the total memory usage of all combined libraries, the values can be configured during module load.
    • #940 Validate the current memory usage when uploading a new library to not exceed the max memory limit.

Changed Behavior

  • Search and Query:
    • #3355, #3635 Expired keys deleted from slave's index, returning an empty array instead of nil.

Bug Fixes

  • Search and Query:

    • #3597 Duplicating alias as output name on FT.AGGREGATE reducer (REDUCE argument) isn't return results.
    • #3654 Added check for @ prefix on GROUPBY fields returnig an error instead of wrong results.
    • #3501 Sorting by 2 or more fields follow the order not ignoring the second argument.
    • #3582 Sorter will set lower rank in documents expired during query time, preventing clients to freeze.

  • JSON:

    • #1025 JSON.TOGGLE key space notification fix.

  • Time series:

    • #1471 Potential crash on MRANGE when aggregating millions of time series.
    • #1469 Potential memory leak in MRANGE after eviction.

  • Triggers and Functions:

    • #913 Do not trigger notifications when Redis is loading from a persistence file.
