Redis Configuration

This section explains how to update Redis configuration both at runtime and persistently.

Redis is an in-memory data store for high-speed caching and lookups. Its performance is critical for ensuring fast access to frequently used data. The key parameter, hash-max-ziplist-value, controls the encoding behavior for hash entries. Tuning this value allows Redis to improve memory management and lookup speed.

The default value of hash-max-ziplist-value may limit performance when storing larger hash entries.

CONFIG GET hash-max-ziplist-value

Parameter Details:

hash-max-ziplist-value: Specifies the maximum size of string elements in hash entries stored using ziplist encoding.
Recommended HASH Value: 512 Max Entries and 64 byte Max value size.
