@laurentgo Within the DrillCursor, the only place I could do such a check
was

My JDBC client for performance testing has a similar mechanism for JDBC
drivers that don't support timeout, but allow for query cancellation by using a
cancelling-trigger thread to sleep until the timeout, before waking up
explicitly cancelling the query. I've simply replicated behaviour that in the
Drill JDBC package. Having a constant check on the time remaining using a
system call like {{System.currentTimeMillis()}} is actually expensive, which is
why I didn't want to have the DrillCursor contantly do that check before
throwing an exception. Can you point to me on which async framework should I be
looking at as well ?
