jasync uses a Connection Pool to manage connections. Under the hood it is using an implementation of an async object pool.

Since version 1.1.0 the object pool is exposed as a separate artifact and it is possible to use it by itself. To do so add the below dependency to your maven project:

<dependency>
  <groupId>com.github.jasync-sql</groupId>
  <artifactId>jasync-pool</artifactId>
  <version>1.1.0</version>
</dependency>

Main classes in the API:

• AsyncObjectPool interface.
• PoolConfiguration - hold the part of the configuration specific to the pool.
• ObjectFactory - interface responsible to create/validate/destroy actual connections.

-- If you're interested in the implementation you can read about it here.
