    • 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 ImmutableOpenMap<String,SegmentsStats.FileStats> getFiles()

    • 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
