Cache¶

A cache holds fast, shared data and counters. Never write security state through cache(): the framework keeps revocation marks and idempotency records in its own security cache instance.

What a module calls¶

from sandloom.sdk.infra import cache

await cache().set("reports:last", "...", ttl_seconds=60)

cache(name="default") returns these operations:

• get, set, add, delete, incr, get_many, set_many;
• compare_and_set, compare_and_delete, behind the feature cas;
• incr_window, incr_many, set_nx_get, set_max: one round trip on Redis and a portable fallback elsewhere.

Drivers¶

redis¶

Set CACHE_URL, or the option url on a named instance. It supports the features cas, get_many and set_many.

Limits. It connects to a single Redis endpoint, with no built-in Sentinel or Cluster client. Use a managed primary endpoint with failover, or a driver package.

For a second cache, add a named instance in Configure backends.
