Class DanglingIndicesState

All Implemented Interfaces:

public class DanglingIndicesState extends Object implements ClusterStateListener
The dangling indices state is responsible for finding new dangling indices (indices that have their state written on disk, but don't exists in the metadata of the cluster), and importing them into the cluster.
  • Field Details


      public static final Setting<Boolean> AUTO_IMPORT_DANGLING_INDICES_SETTING
      Controls whether dangling indices should be automatically detected and imported into the cluster state upon discovery. This setting is deprecated - use the _dangling API instead. If disabled, dangling indices will not be automatically detected.

    • getDanglingIndices

      public Map<Index,IndexMetadata> getDanglingIndices()
      Either return the current set of dangling indices, if auto-import is enabled, otherwise scan for dangling indices right away.

    • findNewDanglingIndices

      public Map<Index,IndexMetadata> findNewDanglingIndices(Map<Index,IndexMetadata> existingDanglingIndices, Metadata metadata)
      Finds new dangling indices by iterating over the indices and trying to find indices that have state on disk, but are not part of the provided metadata, or not detected as dangled already.
