Instance Constructors

  1. new BatchedBufferDecompressor(maxBatchMemorySize: Long, stream: Stream)

    maxBatchMemorySize

    The upper limit in bytes of output memory usage at which a batch should be decompressed. A single table that requires output memory above this limit is allowed but will be decompressed individually.

    stream

    CUDA stream to use

Abstract Value Members

  1. abstract val codecId: Byte

    The codec ID corresponding to this decompressor

  2. abstract def decompressAsync(inputBuffers: Array[BaseDeviceMemoryBuffer], bufferMetas: Array[BufferMeta], stream: Stream): Array[DeviceMemoryBuffer]

    Decompress a batch of compressed buffers

    Decompress a batch of compressed buffers

    inputBuffers

    buffers that contain the compressed input

    bufferMetas

    corresponding metadata for each compressed input buffer

    stream

    CUDA stream to use

    returns

    buffers that contain the uncompressed output

    This must be called after all buffers to be decompressed have been added to retrieve the decompression results.

    This must be called after all buffers to be decompressed have been added to retrieve the decompression results. Note that the decompression may still be occurring asynchronously using the CUDA stream specified when the decompressor was instantiated.

    returns

    decompressed tables
