# Which Problems Are Solved
Cache implementation using a PGX connection pool.
# How the Problems Are Solved
Defines a new schema `cache` in the zitadel database.
A table for string keys and a table for objects is defined.
For postgreSQL, tables are unlogged and partitioned by cache name for
performance.
Cockroach does not have unlogged tables and partitioning is an
enterprise feature that uses alternative syntax combined with sharding.
Regular tables are used here.
# Additional Changes
- `postgres.Config` can return a pxg pool. See following discussion

# Which Problems Are Solved
We identified the need of caching.
Currently we have a number of places where we use different ways of
caching, like go maps or LRU.
We might also want shared chaches in the future, like Redis-based or in
special SQL tables.
# How the Problems Are Solved
Define a generic Cache interface which allows different implementations.
- A noop implementation is provided and enabled as.
- An implementation using go maps is provided
- disabled in defaults.yaml
- enabled in integration tests
- Authz middleware instance objects are cached using the interface.
# Additional Changes
- Enabled integration test command raceflag
- Fix a race condition in the limits integration test client
- Fix a number of flaky integration tests. (Because zitadel is super
fast now!) 🎸🚀
