Patch Releases

Latest News / Releases  

Hazelcast IMDG 4.1.1

New Features

  • Node Aware Partition Grouping: Added the support of partition grouping mechanism in the Hazelcast discovery plugin for Kubernetes. You can create partition groups according to the name of the node which is provided by this plugin and on which the containers/pods run. See the NODE_AWARE section of the IMDG Reference Manual for more information.

Enhancements

  • Introduced a configuration property to ignore errors during
    enabling the XXE protection. This protection works with JAXP 1.5 (Java 7 Update 40)
    and newer. When an older JAXP implementation is added to
    the classpath, e.g., Xerces and Xalan, an exception is thrown.
    The newly introduced property, namely "hazelcast.ignoreXxeProtectionFailures",
    allows you to ignore those exceptions.
    See the System Properties appendix of the IMDG Reference Manual for more information.
  • Updated the Hazelcast Kubernetes plugin dependency to 2.2.1.
  • Separated the hazelcast-sql Maven module into hazelcast-sql-core and hazelcast-sql.
  • Implemented the IMap.entrySet() method for the partition ID set.
