Maximum size of bulk create (or update) for Cloudant?

Question

When using bulk operation with Cloudant. Is there a "hard" limit (size of all documents / number of documents)?

Also: is there a best practice setting? (size of all documents / number of documents per request)?

Answer 1

I understand there is a 65Mb limit in the size of individual documents in Cloudant. Having said that, I would try to avoid getting anywhere near that size of document.

A rule of thumb would be if the size of your documents is over a few tens of kilobytes, you might be better creating more documents and retrieving them using a view.

In terms of bulk operations, I tend to use batches of 500 documents. Bulk operations are a much more efficient way of transferring data between your client software and Cloudant and a 500 document batch size (as long as your document size is reasonable) is a good rule of thumb.

Answer 2

There is no such number that says, how many documents we can update in bulk, but There is a size limit of 1 MB for whole bulk document request object of 1 MB for whole request. if requested data is more than 1 MB then request will be rejected.

As I tested myself with JsonObject with 12 fields, it took around 2K documents to cover 1MB size. But still it can be vary if you small & large content.
