    • ES816HnswBinaryQuantizedVectorsFormat

      public ES816HnswBinaryQuantizedVectorsFormat()
      Constructs a format using default graph construction parameters
    • ES816HnswBinaryQuantizedVectorsFormat

      public ES816HnswBinaryQuantizedVectorsFormat(int maxConn, int beamWidth)
      Constructs a format using the given graph construction parameters.
      Parameters:
      maxConn - the maximum number of connections to a node in the HNSW graph
      beamWidth - the size of the queue maintained during graph construction.

      public ES816HnswBinaryQuantizedVectorsFormat(int maxConn, int beamWidth, int numMergeWorkers, ExecutorService mergeExec)
      Constructs a format using the given graph construction parameters and scalar quantization.
      Parameters:
      maxConn - the maximum number of connections to a node in the HNSW graph
      beamWidth - the size of the queue maintained during graph construction.
      numMergeWorkers - number of workers (threads) that will be used when doing merge. If larger than 1, a non-null ExecutorService must be passed as mergeExec
      mergeExec - the ExecutorService that will be used by ALL vector writers that are generated by this format to do the merge
