Emond Papegaaij created ISPN-8411: ------------------------------------- Summary: Add support for efficient removeAll Key: ISPN-8411 URL: https://issues.jboss.org/browse/ISPN-8411 Project: Infinispan Issue Type: Feature Request Components: Core Affects Versions: 9.1.1.Final, 8.2.8.Final Environment: WildFly 10.1.0, WildFly 11.0.0.CR1, WildFly master, Hibernate 2LC Reporter: Emond Papegaaij 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. -- This message was sent by Atlassian JIRA (v7.5.0#75005)
