Size of each chunk that is uploaded when using B2's large file APIs, in bytes. Minimum value is 5MB; default is 9MB.
Note: there seems to be a bug in the current version of the backblaze-b2 package when the request body upload is > 10 MB, because of a downstream dependency on axios@0.17; once backblaze-b2 updates its dependency on axios, this might be fixed.
Backblaze recommends retrying all uploads at least two times (up to five) in case of errors, with an incrementing delay. We're retrying all uploads 3 times by default.

Generated using TypeDoc
Manages the upload of objects to Backblaze B2.
This supports using Buffers and strings with the "simple APIs". It supports streams too, using either the "simple APIs" if the stream is less than
chunkSize, or the large file APIs otherwise. The selection happens automatically.
