There can be some ambiguity around the maximum csv export size. There's a configuration limit of 10mb which can be increased with limitations.

Adding information on these can help with the if and how much questions:

• < max-old-space-size
• csv is buffered in memory on the main thread, large reports and/or several parallel reports can bring the server down
• response stored in an elasticsearch document, capped by yml http response length, max document size, limited by a blocking http request
