BandanaPersister Underlying distributed cache should not expire

XMLWordPrintable

      CAC went down on 24/10, and we suspect it was because of the bandanaPersister cache being invalidate, causing all requests to issue multiple cache gets all at the same time, drowning out the threadpool and stalling all http requests.

      The BandanaPersister cache is a Near Cache, but the underlying distributed cache expires values if not access for an hour. Since the near cache is guarding these values, they will basically always expire after an hour. Depending on the traffic at that time, this may create the above situation.

      The fix is to remove the expire-after-access-secs property from that particular cache.

            NOTE: when merging this up to the 5.7 branch, care should be taken as the settings file has changes quite a bit since 5.6.x
