Redis 7.2
What's new in Redis 7.2
Redis version 7.2 introduces new capabilities, including improved geospatial queries, and streamlined JSON data manipulation. Performance optimizations, client-side enhancements, and behavioral refinements further improve the efficiency, security, and usability of Redis. Below is a detailed breakdown of these updates.
New features
Geospatial queries with polygon search
Redis Query Engine now supports querying geospatial data using polygon search, enabling developers to efficiently filter and retrieve data within complex geographic boundaries.
Streamlined data manipulation in JSON
JSON now includes two new commands for improved data handling:
JSON.MERGE: Merges a given JSON value into matching paths, allowing more flexible updates.JSON.MSET: Sets or updates multiple JSON values simultaneously based on specified key-path-value triplets, improving efficiency when handling structured data.
Improvements
Existing data structures
Significant performance improvements have been made across Redis data types. Sorted sets, commonly used for gaming leaderboards, now see performance improvements ranging from 30% to 100%.
Additionally, Redis stream consumer tracking has been enhanced to provide better visibility into consumer activity, and blocked stream commands now return a distinct error when the target key no longer exists.
Redis Query Engine improvements
The Redis Query Engine has received several updates, including optimized SORT BY operations and the addition of a new FORMAT response in RESP3, improving both efficiency and readability.
Script execution enhancemets
Client-side tracking now monitors actual keys read during script execution, improving key usage tracking accuracy. Additionally, blocked commands will re-evaluate security checks before execution, ensuring compliance with updated permissions. Standardized ACL failure messages and error codes now provide clearer error handling.
Client and replication enhancements
TLS-based replication now supports Server Name Indication (SNI) to improve compatibility with secure deployments. The HELLO command behavior has also been refined to modify client state only upon successful execution, ensuring more predictable client behavior.
Changes
Breaking changes
Redis 7.2 introduces several backward-incompatible changes. Lua scripts no longer support the print() function, blocking of PFCOUNT and PUBLISH in read-only scripts, and time sampling freezing during command execution. Error handling updates include case changes in error responses, new behavior for ZPOPMIN/ZPOPMAX with count 0, and adjustments to XCLAIM/XAUTOCLAIM. ACL changes affect command categorization and key access permissions, while command introspection now includes per-subcommand statistics. Redis now allows certain CONFIG commands during loading and tracks statistics only when commands are executed.

Expired keys are now deleted from replica indexes
Expired keys are now deleted from Redis Query Engine replica indexes, ensuring that queries return an empty array rather than nil when the data no longer exists.
Other changes
Redis Stack 7.2 no longer includes Graph capabilities. For more details, refer to the RedisGraph End-of-Life Announcement.
