    • addIndexWriterMemoryInBytes

      public void addIndexWriterMemoryInBytes(long indexWriterMemoryInBytes)

    • addVersionMapMemoryInBytes

      public void addVersionMapMemoryInBytes(long versionMapMemoryInBytes)

    • addBitsetMemoryInBytes

      public void addBitsetMemoryInBytes(long bitsetMemoryInBytes)

    • addFiles

      public void addFiles(Map<String,SegmentsStats.FileStats> newFiles)

    • add

      public void add(SegmentsStats mergeStats)

    • getCount

      public long getCount()
      The number of segments.

    • getIndexWriterMemoryInBytes

      public long getIndexWriterMemoryInBytes()
      Estimation of the memory usage by index writer

    • getIndexWriterMemory

      public ByteSizeValue getIndexWriterMemory()

    • getVersionMapMemoryInBytes

      public long getVersionMapMemoryInBytes()
      Estimation of the memory usage by version map

    • getVersionMapMemory

      public ByteSizeValue getVersionMapMemory()

    • getBitsetMemoryInBytes

      public long getBitsetMemoryInBytes()
      Estimation of how much the cached bit sets are taking. (which nested and p/c rely on)

    • getBitsetMemory

      public ByteSizeValue getBitsetMemory()

    • getFiles

      public Map<String,SegmentsStats.FileStats> getFiles()
      Returns a mapping of file extension to statistics about files of that type. Note: This should only be used by tests.

    • getMaxUnsafeAutoIdTimestamp

      public long getMaxUnsafeAutoIdTimestamp()
      Returns the max timestamp that is used to de-optimize documents with auto-generated IDs in the engine. This is used to ensure we don't add duplicate documents when we assume an append only case based on auto-generated IDs

      public void writeTo(StreamOutput out) throws IOException
      Description copied from interface: Writeable
      Write this into the StreamOutput.
