  • Method Details

    • isInSync

      public boolean isInSync()
      Returns true if the shard copy is in-sync and contains the latest data. Returns false if the shard copy is stale or if the shard copy being examined is for a replica shard allocation.
    • getAllocationId

      @Nullable public java.lang.String getAllocationId()
      Gets the allocation id for the shard copy, if it exists.
    • hasMatchingSyncId

      public boolean hasMatchingSyncId()
      Returns true if the shard copy has a matching sync id with the primary shard. Returns false if the shard copy does not have a matching sync id with the primary shard, or this explanation pertains to the allocation of a primary shard, in which case matching sync ids are irrelevant.
    • getMatchingBytes

      public long getMatchingBytes()
      Gets the number of matching bytes the shard copy has with the primary shard. Returns Long.MAX_VALUE if hasMatchingSyncId() returns true. Returns -1 if not applicable (this value only applies to assigning replica shards).
    • getStoreException

      @Nullable public java.lang.Exception getStoreException()
      Gets the store exception when trying to read the store, if there was an error. If there was no error, returns null.
