Radim Vansa commented on ISPN-8411:
-----------------------------------

Uh, seems I got it wrong: the BulkOperationCleanupAction seems to call {{RegionAccessStrategy.removeAll()}}, not {{evictAll()}} - that explains the behaviour you're seeing.

It should be possible to replace this with the clear() call for non-transactional caches, I've implemented the fix here and it seems to pass the testsuite: https://github.com/rvansa/hibernate-orm/tree/HHH-12036

> Infinispan currently does not seem to implement an efficient way to clear an entire cache cluster-wide. This forces Hibernate to remove all entries one by one when a cache region needs to be cleared, for example when a buld CriteriaUpdate or CriteriaDelete is used.
> The behavior we are observing is:
> # All nodes in the cluster are queried for the keyset in a region
> # A lock seems to be in place for this region for the duration of the commit
> # The initiating node constructs a message with {{InvalidateCommands}} for all keys
> # This large message (230MB for 200k entries) is sent to all nodes in the cluster
> For large caches this can take very long. We had to increase the remote-timeout to 60 seconds to prevent timeouts. During this time, the entire cluster is locked an busy processing the cache invalidations. As you can understand, this is not a workable solution for us. On some places we can prevent the cache clear by updating the records one by one, but in other places this is not an option.
