Re: Stop a long running query

[Rahul Goswami <ra...@gmail.com>]

Hi Mikhail,
Since the timeAllowed parameter would cause partial results to return, the
response may not be a correct one. In certain scenarios, it might be better
to return a failure rather than partial results.

Also, a query may spend more time in faceting than in the query phase.
Since the timeAllowed parameter is only checked in the query expansion and
doc collection phase, it does not intercept faceting, causing it to
continue running and consume resources when terminating the query might be
a better option.

Hope that helps elaborate my requirement (?)

Thanks,
Rahul

Hello, Rahul.
Well, if facets are counted over docvalues or method=enum and hit directory
I/O and abandoned by ExitableDirectoryOrSomtehing.  see
CloudExitableDirectoryReaderTest.
If this resolution is not enough one can extend FacetComponent and check
timeAllowed inside the routine.
The first statement isn't really reasonable to me - let;s say a request
proceeded about %50 and got some results when timeAllowed exceeded. At this
time, no matter if it responds with half backed results or with just an
exception flag. Resources were already spent for calculation.
