Storage Services¶
The services defined by the storage
application are listed below, and will vary depending on settings.
With SQL blob storage¶
When the blob storage is of “sql” type, the following services are available:
storage:
blobs:
type: sql
Final class for a service collection. Iterate on it to get a flattened (one level) and merged (services with same name that allows overrides are merged together) list of services.
- service storage harp_apps.storage.services.sql.SqlStorage ¶
Base:
harp_apps.storage.types.storage.IStorage
Main storage facade, most probably based on the underlying sql/sqlalchemy implementation.
- service storage.blobs harp_apps.storage.services.blob_storages.sql.SqlBlobStorage ¶
Base:
harp_apps.storage.types.IBlobStorage
SQL based Blob Storage.
- service storage.engine harp_apps.storage.engines.SQLAlchemyEngine ¶
Base:
sqlalchemy.ext.asyncio.AsyncEngine
SQLAlchemy Engine.
- url: NoneType = None¶
- service storage.worker harp_apps.storage.worker.StorageAsyncWorkerQueue ¶
Storage async worker
With Redis blob storage¶
When the blob storage is of “redis” type, the following services are available:
storage:
blobs:
type: redis
Final class for a service collection. Iterate on it to get a flattened (one level) and merged (services with same name that allows overrides are merged together) list of services.
- service storage harp_apps.storage.services.sql.SqlStorage ¶
Base:
harp_apps.storage.types.storage.IStorage
Main storage facade, most probably based on the underlying sql/sqlalchemy implementation.
- service storage.blobs harp_apps.storage.services.blob_storages.redis.RedisBlobStorage ¶
Base:
harp_apps.storage.types.IBlobStorage
Redis based Blob Storage.
- client: LazyServiceReference = LazyServiceReference('storage.redis')¶
- service storage.engine harp_apps.storage.engines.SQLAlchemyEngine ¶
Base:
sqlalchemy.ext.asyncio.AsyncEngine
SQLAlchemy Engine.
- url: NoneType = None¶
- service storage.redis harp_apps.storage.services.redis.Redis ¶
Base:
redis.asyncio.Redis
Asynchronous Redis Client.
- service storage.worker harp_apps.storage.worker.StorageAsyncWorkerQueue ¶
Storage async worker
To customize the Redis client, you can override the blobs.redis
settings in your configuration:
storage:
blobs:
type: redis
redis:
url: redis://localhost:6379/0 # this is the default, only set to override
