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:
- AWS DynamoDB
- Aerospike
- Azure Blob Storage
- Azure CosmosDB
- Azure Table Storage
- Cassandra
- Cloud Firestore (Datastore mode)
- CloudState
- Couchbase
- Etcd
- HashiCorp Consul
- Hazelcast
- Memcached
- MongoDB
- PostgreSQL
- Redis
- RethinkDB
- SQL Server
- Zookeeper
Implementing a new State Store
A compliant state store needs to implement one or more interfaces: Store and TransactionalStore.
The interface for Store:
type Store 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 TransactionalStore:
type TransactionalStore interface {
Init(metadata Metadata) error
Multi(reqs []TransactionalRequest) error
}
See the documentation site for examples.
