Class MetaDataIndexUpgradeService

  • public class MetaDataIndexUpgradeService
    extends java.lang.Object
    This service is responsible for upgrading legacy index metadata to the current version

    Every time an existing index is introduced into cluster this service should be used to upgrade the existing index metadata to the latest version of the cluster. It typically occurs during cluster upgrade, when dangling indices are imported into the cluster or indices are restored from a repository.

        public IndexMetaData upgradeIndexMetaData​(IndexMetaData indexMetaData,
                                                  Version minimumIndexCompatibilityVersion)
        Checks that the index can be upgraded to the current version of the master node.

        If the index does not need upgrade it returns the index metadata unchanged, otherwise it returns a modified index metadata. If index cannot be updated the method throws an exception.
