-----------------------------------
Summary: Use prepare statement for query syntax and semantic
validation
Key: LENS-332
URL: https://issues.apache.org/jira/browse/LENS-332
Project: Apache Lens
Issue Type: Improvement
Components: driver-jdbc
Reporter: Sushil Mohanty
Assignee: Sushil Mohanty
Currently we are using "select roughly" for query validation in jdbc driver.
Rough query can take more time based on the query complexity and can't
guarantee to finish <50ms. On the other hand prepare query is very light weight
and we can expect it to finish in defined threshold and is supported by major
DBMS.
