Cache

What core/cache stores, invalidation and when not to rely on it.

What it is

core/cache is a small in-process TTL map: Get, Set, Delete, DeletePrefix, Clear. Separate caches exist for security rule compilation and XML id resolution inside the ORM.

Invalidation

After security XML/CSV sync, rule caches are invalidated. Do not assume values survive process restart or appear on other hosts.

Compile and run

No special flag. Cache lives in the running server. Restart clears process memory.

What not to do

• Do not store authoritative business state only in core/cache.
• Do not expect Redis semantics. There is no distributed cache in core.

Next step

Author addons against SDK.
