Use With zodburi

This package also enable the use of the postgres://, mysql:// and oracle:// URI schemes for zodburi. For more information about zodburi, please refer to its documentation. This section contains information specific to the these schemes.

URI schemes

The postgres:// , mysql:// and oracle:// URI schemes can be passed as zodbconn.uri to create a RelStorage PostgresSQL, MySQL or Oracle database factory. The uri should contain the user, the password, the host, the port and the db name e.g.:

postgres://someuser:somepass@somehost:5432/somedb?connection_cache_size=20000
mysql://someuser:somepass@somehost:5432/somedb?connection_cache_size=20000

Because oracle connection information are most often given as dsn, the oracle uri should not contain the same information as the other, but only the dsn :

oracle://?dsn="HERE GOES THE DSN"

Query String Arguments

The URI scheme also accepts query string arguments. The query string arguments honored by this scheme are as follows.

RelStorage-constructor related

These arguments generally inform the RelStorage constructor about values of the same names :

cache_local_mb, commit_lock_timeout, commit_lock_id, read_only, shared_blob_dir, keep_history, pack_gc, pack_dry_run, strict_tpc, create, blob_cache_size, blob_cache_size_check, blob_cache_chunk_size, replica_timeout, pack_batch_timeout, pack_duty_cycle, pack_max_delay, name, blob_dir, replica_conf, cache_module_name, cache_prefix, cache_delta_size_limit, cache_servers
