> Implement a coordinator startup flag that limits the max length (number of characters) of the insert DML statement that inserts records into the impala_query_log table.
> The purpose of this flag is to ensure that workload management does not generate an insert DML statement that exceeds Impala's max length for a sql statement (approximately 16 megabytes or 16 million characters).
