[jira] [Updated] (CAY-2009) Non-blocking connection pool
[ https://issues.apache.org/jira/browse/CAY-2009?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Andrus Adamchik updated CAY-2009:
---------------------------------
Description:
This task is a complete rewrite of Cayenne JDBC connection pool (PoolManager). The new version is a non-blocking pool that supports all the same features as the old one (including recently added validation) except:
* it does not have any synchronization, so expected throughout is much higher.
* it is not based on arcane ConnectionPoolDataSource API. Instead it is created with a non-pooling DataSource, and is much easier to create manually and test.
* we use a new package - org.apache.cayenne.datasource instead of org.apache.cayenne.conn
Hopefully the resulting DataSource will perform on par with the best 3rd party ones, but will remain simple with a bare minimum of functionality, as originally envisioned.
