Per docs, if the mysql connector is JDBC2 compliant then it should use the Connection.isValid API to test a connection. (https://docs.oracle.com/javase/8/docs/api/java/sql/Connection.html#isValid-int-) This would significantly reduce query lags and API throughput, as for every SQL query one or two SELECT 1 are performed everytime a Connection is given to application logic. This should only be accepted when the driver is JDBC4 complaint. Signed-off-by: Rohit Yadav <rohit.yadav@shapeblue.com> |
