Appwrite now serializes key-value cache entries in a compact binary format instead of JSON. This applies to list responses cached with a ttl and to internal entries such as sessions, API keys, and table schemas.
In benchmarks, a cached page of 1,000 rows or more consumed 67% to 69% less memory, and cached listRows throughput increased by up to 29%. The change ships in self-hosted Appwrite 2.3 and requires no migration: existing JSON entries are treated as cache misses and rewritten in the binary format.
