class swh.storage.postgresql.storage.Storage(db: str | Connection[Any], objstorage: Dict | None = None, min_pool_conns: int = 1, max_pool_conns: int = 10, journal_writer: Dict[str, Any] | None = None, query_options: Dict[str, Dict[str, Any]] | None = None)

SWH storage datastore proxy, encompassing DB and object storage

Instantiate a storage instance backed by a PostgreSQL database and an objstorage.

When db is passed as a connection string, then this module automatically manages a connection pool between min_pool_conns and max_pool_conns. When db is an explicit psycopg connection, then min_pool_conns and max_pool_conns are ignored and the connection is used directly.

Parameters:

• db – either a libpq connection string, or a psycopg connection

• objstorage – configuration for the backend ObjStorage; if unset, use a NoopObjStorage

• min_pool_conns – min number of connections in the psycopg pool

• max_pool_conns – max number of connections in the psycopg pool

• journal_writer – configuration for the JournalWriter

• query_options –

  configuration for the sql connections; keys of the dict are the method names decorated with db_transaction() or db_transaction_generator() (eg. content_find()), and values are dicts (config_name, config_value) used to configure the sql connection for the method_name. For example, using:

  {"content_get": {"statement_timeout": 5000}}
  

  will override the default statement timeout for the content_get() endpoint from 500ms to 5000ms.

  See swh.core.db.common for more details.
