public class StoreStats extends Object implements Writeable, org.elasticsearch.common.xcontent.ToXContentFragment
  • Field Details

    • UNKNOWN_RESERVED_BYTES

      public static final long UNKNOWN_RESERVED_BYTES
      Sentinel value for cases where the shard does not yet know its reserved size so we must fall back to an estimate, for instance prior to receiving the list of files in a peer recovery.

      Throws:
      IOException
    • StoreStats

      public StoreStats(long sizeInBytes, long totalDataSetSizeInBytes, long reservedSize)
      Parameters:
      sizeInBytes - the size of the store in bytes
      totalDataSetSizeInBytes - the size of the total data set in bytes, can differ from sizeInBytes for shards using shared cache storage
      reservedSize - a prediction of how much larger the store is expected to grow, or UNKNOWN_RESERVED_BYTES.

    • totalDataSetSize

      public ByteSizeValue totalDataSetSize()
    • getTotalDataSetSize

      public ByteSizeValue getTotalDataSetSize()
    • totalDataSetSizeInBytes

      public long totalDataSetSizeInBytes()
    • getReservedSize

      public ByteSizeValue getReservedSize()
      A prediction of how much larger this store will eventually grow. For instance, if we are currently doing a peer recovery or restoring a snapshot into this store then we can account for the rest of the recovery using this field. A value of -1B indicates that the reserved size is unknown.
