Changed Features

Internal Query Retries

The internal SQL queries that MaxScale executes to load database users as well as monitor the database itself can now be automatically retried if they are interrupted. The new global parameter, query_retries controls the number of retry attempts each query will receive if it fails due to a network problem. The query_retry_timeout global parameter controls the total timeout for the retries.

To enable this functionality, add query_retries=<number-of-retries> under the[maxscale] section where is a positive integer.
