Redis 8.8 Released With New Array Data Structure, More Performance Optimizations

Written by Michael Larabel in Programming on 25 May 2026 at 06:05 AM EDT. 4 Comments
Redis 8.8 reached GA today for the Redis open-source project providing a high performance, in-memory data store.

Notable with Redis 8.8 is introducing an Array data structure. Yes, finally having native array support within Redis for use-cases like aggregating or grep'ing data remotely or when having data dependent upon the relative position. Details on the new array type for Redis can be found via this pull that landed the array support.

Redis 8.8 also brings new performance improvements like now enabling link-time optimizations (LTO) by default for x86_64 release builds, improving thread utilization, reducing FFI overhead by porting some code to Rust, some ARM64 optimizations, batched prefetch for more operations, and various other performance optimizations.
