Handle async-xsite in parallel ------------------------------ Key: ISPN-10657 URL: https://issues.jboss.org/browse/ISPN-10657 Project: Infinispan Issue Type: Enhancement Components: Cross-Site Replication Affects Versions: 10.0.0.CR2 Reporter: Pedro Ruivo Assignee: Pedro Ruivo Priority: Major Fix For: 10.0.0.CR3, 9.4.17.Final Asynchronous cross-site replication relies on the ordering of the write operation to ensure data consistency. This ordering is provided by JGroups; it only delivers the next request after the first one is completed. This order contains updates for multiple caches and keys. What is proposed here is to handle different keys/cache updates in parallel. It should improve the response time, however, there is no free lunch. The following is expected: * An increase of CPU utilization: it may spawn new threads to handle different keys update in parallel * An increase in memory: it chains the updates (queue)
