io.agroal.pool

Class Poolless

java.lang.Object

io.agroal.pool.Poolless

All Implemented Interfaces:

AgroalDataSourceConfiguration.MetricsEnabledListener, Pool, AutoCloseable

public final class Poolless
extends Object
implements Pool

Alternative implementation of ConnectionPool for the special case of flush-on-close (and min-size == 0) In particular, this removes the need for the executor. Also there is no thread-local connection cache as connections are not reused
