Jaideep Dhok commented on LENS-188:
-----------------------------------
setFetchSize should be done in JdbcDriver as well so that irrespective of the
consumers of result set, fetch size is always set.
> JdbcDriver should call setFetchSize

> ResultSet formatter iterates over in memory result's all rows and writes them
> to disk. Fetch size behaviour is highly driver specific. So we should
> explicitly call setFetchSize on InMemoryResultSet and also allow specific
> drivers to add their custom settings on the statement before issuing a query.
