State Stores
State Stores provide a common way to interact with different data store implementations, and allow users to opt-in to advanced capabilities using defined metadata.
Currently supported state stores are:
- Redis
- HashiCorp Consul
- Etcd
- Cassandra
- Azure CosmosDB
- Memcached
Implementing a new State Store
A compliant state store needs to implement one or more interfaces: StateStore and TransactionalStateStore.
The interface for StateStore:
type StateStore interface {
Init(metadata Metadata) error
Delete(req *DeleteRequest) error
BulkDelete(req []DeleteRequest) error
Get(req *GetRequest) (*GetResponse, error)
Set(req *SetRequest) error
BulkSet(req []SetRequest) error
}
The interface for TransactionalStateStore:
type TransactionalStateStore interface {
Init(metadata Metadata) error
Multi(reqs []TransactionalRequest) error
}
See the documentation repo for examples.
