-----------------------------------
Summary: DrillConnectionImpl#isValid() doesn't correspond JDBC API
Key: DRILL-8009
URL: https://issues.apache.org/jira/browse/DRILL-8009
Project: Apache Drill
Issue Type: Bug
Components: Client - JDBC
Reporter: Maksym Rymar
Assignee: Maksym Rymar
{{DrillConnectionImpl#isValid()}} doesn't correspond [Java JDBC API
documentation|https://docs.oracle.com/javase/7/docs/api/java/sql/Connection.html#isValid(int)].
Current implementation doesn't do actual connection verify and doesn't cover
cases like drillbit termination and network issues.
{{java.sql.Connection#isValid()}} (which extends {{DrillConnectionImpl}})
widely used in JDBC connection pools like HikariCP and without right
implementation, Drill JDBC driver cannot be used with them, because connections
will keep alive forever.
