Config to connect to a Microsoft SQL Server database.

​

Attributes

​

url

The JDBC connection string. See https://learn.microsoft.com/en-us/sql/connect/jdbc/building-the-connection-url?view=sql-server-ver16 for more information.

​

auto_multi_column_array_conversion

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

​

column_clustered_queries

Control which queries will use clustering columns.

​

feeding_query_timeout

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

• the initial load to feed aggregate_providers and hierarchies;
• the refresh operations.

​

lookup_mode

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

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

​

password

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.

​

query_timeout

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