Semen Boikov commented on IGNITE-7308:
--------------------------------------
I recall that this is updated in discovery thread since 'registeredCaches'
(which is stored in ClusterCachesInfo) is also updated in discovery thread. It
is not possible just move caches.init to exchange, since we need
'registeredCaches' state at the moment node was started/activated. I think
correct fix can be save 'registeredCaches' somewhere (e.g. in ExchangeActions)
and update CacheAffinitySharedManager.caches using this saved state.
