v2.3.11 Release

• Make getTotalBytesProcessed() and getCacheHit() nullable. A null value indicates that the total_bytes_processed or cache_hit fields were omitted from a query response, generally because they are not applicable to some query. This could be due to the query being non-standard SQL, e.g. storing procedures, or due to the configuration of the database, e.g. row-level ACL's prevent reporting of total_bytes_processed to avoid leaking table size information. They are liable to be null for any query.
• Add a timeoutMs JDBC parameter to override the default timeout, which is effectively indefinite.
