1

• Optional observability event stream added. Provides a flexible mechanism for monitoring the healthiness of the pool via logs and metrics.
• Configuration got isolated into a DSL, which will allow to provide new configurations without breaking backward compatibility.

0.10.1

• Avoid releasing connections on exceptions thrown in session

0.9

• Maximal lifetime added for connections. Allows to refresh the connections in time cleaning up the resources.

Breaking:

• The acquisition timeout is now non-optional.

Fix excessive connections during releases due to race conditions.

0.8.0.5

Fix connections not returning to the pool on exceptions.

0.8

release became reusable. You can use it to destroy the whole pool (same as before), but now also you can use it to reset the connections.

Acquisition timeout added.

• Removed PoolIsReleasedUsageError
• acquire extended with the acquisition timeout parameter
• acquireDynamically extended with the acquisition timeout parameter
