Infinispan 11.0.0.CR1

Dear Infinispan community,

we’ve just released 11.0.0.CR1 which comes loaded with quite a few features and improvements.

Cross-Site Replication Improvements

The cross-site replication feature received two major improvements:

  • Support for multiple site masters

    The new algorithm is able to take advantage of multiple site masters, distributing load between them. If your environment is capable, increase the number of site masters in RELAY2 configuration:

    <relay.RELAY2 site="LON" max_site_masters="1000"/>
  • Conflict detection and resolution for Asynchronous Cross-Site Replication

    Taking advantage of vector clocks, in asynchronous mode, Infinispan is able to detect conflicts. A conflict happens when 2 or more sites update the same key at the same time. Conflicts are resolved based on the site’s names. Updates from the site lexicographically lower, take priority, in case of conflicts. As an example, if you have 3 sites, LON, NYC and SFO, conflicts between LON and NYC discards updates from NYC and keeps the updates from LON. You can choose the priority by prepending a number to the site name. For example, if you want updates from NYC to take priority, you can set the site name to “1-NYC”.

In a future update, Infinispan will allow you to set a custom conflict resolution algorithm.
