Is the order a bulk request guaranteed? I am making Nest calls from C# by using the BulkDescriptor to perform both inserts, updates, and deletes against a 2 node cluster. I wrote a simple application testing whether or not order is preserved and after hours of running, I had no notifications that it is not ordered. I tried looking through the BulkProcessor class in source code and it seems that it has a concurrent value of 1 by default, where 0 is stated as single thread. Please let me know if I can rely on the operations happening in a specific order. Thank you. ---

You can rely on the fact that operations on the same document (same \_index, \_type and \_id) will be in order. However you can't assume anything for documents that have different indices/types/ids. ---
