Added Support For beginRequest and endRequest #2079

Closed

#2071 Added support of beginRequest and endRequest from JDBC 4.3 onwards.

  • beginRequest hints to the driver that a request, an independent unit of work, is beginning on this connection.
  • endRequest hints to the driver that a request has completed.

Both these calls function to let the driver know when a connection is checked out of the pool and back into the pool.These boundaries can help driver for load balancing and other stuff. These functions are driver specific and may not do anything.

The changes look good! Just the comments could be removed to be consistent with the codebase.

This logic should not be executed every time. Can this be moved somewhere so the calculation of if the feature is supported is only run once. Calling getMetaData might not be cheap.

@lfbayer FYI I've asked Deeptanshu to close this PR as his internship at Oracle is now over. We will continue his work in PR 2126.
