18.4. Pool Filling
The number of connections in the pool is controlled by the pool sizes.
- <min-pool-size/> - When the number of connections falls below this size, new connections are created
- <max-pool-size/> - No more than this number of connections are created
- <prefill/> - Feature Request has been implemented for 4.0.5.
The pool filling is done by a separate "Pool Filler" thread rather than blocking application threads.
Important
Connection pools are filled to their
min-pool-size only on their first usage.
