I'm seeing conflicting info on this. If I make 1 request to bulk insert 10 documents, how many write operations does that count for?
These two SO posts suggest 1, but I'm wondering if they are outdated.
How do calculate IO operations in Cloudant account for Bluemix pricing? (throughput - lookups, reads, writes, queries) How do Bulk operations in Cloudant account for Bluemix pricing? (throughput - lookups, writes, queries)
The information you refer to is correct. A bulk write will (currently) be counted as a single write, and not be split apart into its constituent documents when it comes to billing.
However: note that Cloudant has always recommended that you don’t rely on this behaviour, as it might change somewhere down the line.
