final class atoti_directquery_jdbc.ConnectionConfig

Config to connect to an external database through JDBC.

auto_multi_column_array_conversion : AutoMultiColumnArrayConversion | None = None

When not None, multi-column array conversion will be performed automatically.

column_clustered_queries : ‘all’ | ‘feeding’ = ‘feeding’

Control which queries will use clustering columns.

feeding_query_timeout : Duration = datetime.timedelta(seconds=3600)

Timeout for queries performed on the external database during feeding phases. The feeding phases are:

lookup_mode : ‘allow’ | ‘warn’ | ‘deny’ = ‘warn’

Whether lookup queries on the external database are allowed. Lookup can be very slow and expensive as the database may not enforce primary keys.

max_sub_queries : Annotated[int, Field(gt=0)] = 500

Maximum number of sub queries performed when splitting a query into multi-step queries.

password : str | None = None

The password to connect to the database. Passing it in this separate attribute prevents it from being logged alongside the connection string. If None, a password is expected to be present in url.

password_parameter_name : str | None = None

The name of the query string parameter in which password should be added to url. Unused when password is None, required when it is not.

query_timeout : Duration = datetime.timedelta(seconds=300)

Timeout for queries performed on the external database outside feeding phases.

sql_dialect_key : str

The key of the SQL dialect to use. The dialect will typically be provided with an extra JAR.

url : str

The JDBC connection string.
