3.7.50. DupCache Previous topic Parent topic Child topic Next topic

This optional parameter defines if duplicate cache is implemented locally within the process, shared between processes with mmapped memory or if a Gossip cluster will provide a global shared cache for detecting duplicate requests. Defaults to ‘local’.
For more about Gossip, see Section 3.129. <GossipRedis> and the configuration sample goodies/farmsize.cfg.
Possible values are:
  • local: Local to each process. The duplicate cache is not shared
  • shared: Shared between processes on the same server. Requires Cache-FastMmap
  • global: Shared between processes using the Gossip framework
