|How long the digest worker thread keeps working on flushing the contents of in-memory buffers at shutdown
How long the digest worker thread should keep working on flushing the contents of in-memory buffers when LogScale is told to shut down using "sigterm" (normal shutdown). Default to 300 seconds as millis. If too low, then the next startup will need to start further back in time on the ingest queue.
Optional: Allow the LogScale JVM to exit if it detects more time is spent
on GC than on actual computations. See
