final class atoti_jdbc.JdbcPingDiscoveryProtocol

remove_all_data_on_view_change : bool = True

“Defined by the FILE_PING protocol. See http://jgroups.org/manual4/index.html#_removal_of_zombie_files.select_all_pingdata_sql : str | None = None
update_store_on_view_change : bool | None = None
Defined by the FILE_PING protocol. WhenTrue, the coordinator updates the backend store (JDBC table) on every view change, including when members leave or crash.
If False, the table is only updated on joins.
Enabling this ensures stale entries from crashed nodes (zombies) are removed.
See http://jgroups.org/manual4/index.html#_jdbc_ping.
url : Annotated[str, AfterValidator(normalize_jdbc_url)]
The JDBC connection string of the database. The"jdbc" scheme is optional but the database specific scheme (such as "h2") is mandatory.
For instance:
