Processing a call usually entails determining which S3 API requests that need to be enqueued, but does **not** entail making any of the S3 API data transferring requests needed to perform the transfer. The threads controlled by ``max_request_concurrency`` is responsible for that. :param multipart_chunksize: The size of each transfer if a request becomes a multipart transfer. :param max_request_queue_size: The maximum amount of S3 API requests that can be queued at a time. :param max_submission_queue_size: The maximum amount of TransferManager method calls that can be queued at a time. :param max_io_queue_size: The maximum amount of read parts that can be queued to be written to disk per download. The default size for each elementin this queue is 8 KB. :param io_chunksize: The max size of each chunk in the io queue. Currently, this is size used when reading from the downloaded stream as well. :param num_download_attempts: The number of download attempts that will be tried upon errors with downloading an object in S3. Note that these retries account for errors that occur when streaming down the data from s3 (i.e. socket errors and read timeouts that occur after receiving an OK response from s3). Other retryable exceptions such as throttling errors and 5xx errors are already retried by botocore (this default is 5). The ``num_download_attempts`` does not take into account the number of exceptions retried by botocore. :param max_in_memory_upload_chunks: The number of chunks that can be stored in memory at a time for all ongoing upload requests. This pertains to chunks of data that need to be stored in memory during an upload if the data is sourced from a file-like object. The total maximum memory footprint due to a in-memory upload chunks is roughly equal to: max_in_memory_upload_chunks * multipart_chunksize + max_submission_concurrency * multipart_chunksize ``max_submission_concurrency`` has an affect on this value because for each thread pulling data off of a file-like object, they may be waiting with a single read chunk to be submitted for upload because the ``max_in_memory_upload_chunks`` value has been reached by the threads making the upload request. :param max_in_memory_download_chunks: The number of chunks that can be buffered in memory and **not** in the io queue at a time for all ongoing download requests. This pertains specifically to file-like objects that cannot be seeked. The total maximum memory footprint due to a in-memory download chunks is roughly equal to: max_in_memory_download_chunks * multipart_chunksize :param max_bandwidth: The maximum bandwidth that will be consumed in uploading and downloading file content. The value is in terms of bytes per second.
