You can limit the rate at which new queries start by setting QUERY_COORDINATOR_START_RATE_LIMIT and QUERY_COORDINATOR_START_RATE_LIMIT_INTERVAL_MILLIS. The QUERY_COORDINATOR_START_RATE_LIMIT parameter sets the maximum number of new queries that can start within the time interval specified by QUERY_COORDINATOR_START_RATE_LIMIT_INTERVAL_MILLIS. When the limit is reached, query execution is delayed until the next interval.
