[Exist-open] caching queries in the query-pool forever (@timeout-check-interval="-1")

[Xma M. <mon...@gm...>]

i am learning a lot about eXist and how it uses queries and the query
cache.  im studying how it impacts performance on high concurrency
applications.  when i have something more concise to share about this, i
will post my findings here.

in the mean time, can anyone weigh in on this question?  in conf.xml, is
there a reason that i should not set the @timeout-check-interval on the
<query-pool/> to -1?  i have tested and if the XQuery is modified, the
change is detected and the query is forcibly recompiled.

however, if no change has actually occurred, i dont want my compiled
queries to time-out and be recycled and have to be recompiled again.  in
the middle of high concurrency, that's an expensive (and potentially
blocking) operation.

the current time-out interval is (@timeout) is set to 120000 (2 minutes i
think).

anyone know reason that i should not do this?

thanks!
