The configuration option
``[compute]resource_provider_association_refresh`` can now
be set to zero to disable refresh entirely. This follows on from `bug
1767309`_ allowing more aggressive reduction in the amount of traffic to
the placement service.
The cache can be cleared manually at any time by sending SIGHUP to the
compute process. This will cause the cache to be repopulated the next time
the data is accessed.
