Setting polling intervals for distributed pools

By default, all distributed pools are nonpolling pools — they query the distributed pending queue in real time whenever a request associated with the pool is submitted to the queue.

For pools with heavy activity, make them polling pools, which query the distributed pending queue at specified intervals. For example, suppose a pool is configured to query the queue every 12 hours. If a request associated with the pool is submitted to the queue 1 hour after the pool's last query, the request is not processed for 11 hours. Use this option to shift the processing of noncritical requests to periods of low database activity.

To set a polling interval for a distributed pool, use the Distributed Pool editor. See Creating distributed pools.

Default pool and polling

When a distributed pool is disabled, the operations associated with it are processed by the default pool. If the default pool is a polling pool, the operations are not immediately processed. Consider this when setting up your pools.
