  getFullFileDispatcherThreadpoolSize

  public int getFullFileDispatcherThreadpoolSize()

  Returns the size of the thread pool used internally to handle batches of full file uploads. The default value is 5.

  Returns:

  The configured size of the dispatcher thread pool.

  setFullFileDispatcherThreadpoolSize

  public GPUdbFileHandler.Options setFullFileDispatcherThreadpoolSize(int fullFileDispatcherThreadpoolSize) throws GPUdbException

  Sets the size of the thread pool used internally to handle batches of full file uploads. The default value is 5.

  Parameters:

  fullFileDispatcherThreadpoolSize - The number of threads that the file dispatcher pool should use.

  Returns:

  The current GPUdbFileHandler.Options instance.

  Throws:

  GPUdbException - If the given thread pool size is invalid in the current execution environment.

  getFileSizeToSplit

  public long getFileSizeToSplit()

  Gets the value of the file split size—files smaller than this size will be uploaded in batches up to this size, and files greater than this size will be uploaded in parts up to this size.

  Returns:

  The file split size in bytes.

  • setFileSizeToSplit(long)

  getMaxUploadBytesInFlight

  public long getMaxUploadBytesInFlight()

  Gets the ceiling on full-file upload payloads held in memory at once, across batches submitted to the dispatcher but not yet collected.

  Returns:

  the maximum in-flight upload size in bytes.

  See Also:

  • setMaxUploadBytesInFlight(long)

  setMaxUploadBytesInFlight

  public void setMaxUploadBytesInFlight(long maxUploadBytesInFlight) throws GPUdbException

  Sets the ceiling on full-file upload payloads held in memory at once.

  Lower it further than the default where memory is tight: an upload then waits for outstanding batches to finish more often, trading throughput for a smaller peak. Raise it to enable more thoughput where memory is plentiful.

  Parameters:

  maxUploadBytesInFlight - The ceiling in bytes; must be positive.

  Throws:

  GPUdbException

  setFileSizeToSplit

  public void setFileSizeToSplit(long fileSizeToSplit) throws GPUdbException

  Throws:

  GPUdbException
