+         multipart_chunksize
+            Specifies partition size in bytes of each part of a multipart
+            upload made by the Boto3 client. To calculate the maximum size of a
+            Boto3 client multipart upload, multiply the multipart_chunk value
+            by the maximum number of parts the API allows. For AWS S3 this
+            limit is 10000. Values can be provided either in bytes or as
+            human-readable values (e.g., "150M" to represent 150 mebibytes).
+
+         multipart_threshold
+            Files larger than this threshold will be partitioned into parts,
+            uploaded separately by the Boto3 client, and then combined into a
+            single object. Otherwise, files smaller than this threshold will be
+            uploaded by the Boto3 client in a single stream.
