maxSlots property
A target limit on the rate of slot consumption by this query.
If set to a value > 0, BigQuery will attempt to limit the rate of slot consumption by this query to keep it below the configured limit, even if the query is eligible for more slots based on fair scheduling. The unused slots will be available for other jobs and queries to use. Note: This feature is not yet generally available.
Optional.
