* config,docs: add databroker storage backend configuration
* cache: allow configuring which backend storage to use
Currently supported types are "memory", "redis".
* pkg/storage: add redis storage backend
* pkg/storage/redis: set record create time correctly
* pkg/storage/redis: add docs
* pkg/storage/redis: run test with redis tag only
* pkg/storage/redis: use localhost
* pkg/storage/redis: use 127.0.0.1
* pkg/storage/redis: honor REDIS_URL env
* .github/workflows: add missing config for redis service
* .github/workflows: map redis ports to host
* pkg/storage/redis: use proto marshaler instead of json one
* pkg/storage/redis: use better implementation
By using redis supported datastructure:
- Hash for storing record
- Sorted set for storing by version
- Set for storing deleted ids
List operation will be now performed in O(log(N)+M) instead of O(N) like
previous implementation.
* pkg/storage/redis: add tx to wrap redis transaction
* pkg/storage/redis: set record type in New
* pkg/storage/redis: make sure tx commands appear in right order
* pkg/storage/redis: make deletePermanentAfter as argument
* pkg/storage/redis: make sure version is incremented when deleting
* pkg/storage/redis: fix linter
* pkg/storage/redis: fix cmd construction
* pkg: add storage package
Which contains storage.Backend interface to initial support for multiple
backend storage.
* pkg/storage: add inmemory storage
* internal/databroker: use storage.Backend interface
Instead of implementing multiple databroker server implementation for
each kind of storage backend, we use only one databroker server
implementation, which is supported multiple storage backends, which
satisfy storage.Backend interface.
