An earlier change [1] allowed [compute]resource_provider_association_refresh to be set to zero to disable the resource tracker's periodic refresh of its local copy of provider traits and aggregates. To allow for out-of-band changes to placement (e.g. via the CLI) to be picked up by the resource tracker in this configuration (or a configuration where the timer is set to a high value) this change clears the provider tree cache when SIGHUP is sent to the compute service. The next periodic will repopulate it afresh from placement. [1] Iec33e656491848b26686fbf6fb5db4a4c94b9ea8 Change-Id: I65a7ee565ca5b3ec6c33a2fd9e39d461f7d90ed2

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.
