Andrei Prigorshnev ad05924bdf DEV: Do one query per month when exporting chat messages (#22746) ... We did some testing and saw that making one query per month is cheaper than querying all chat messages at ones. Note that even though the export job will be performing one query per month, the exported messages will be streamed into a single CSV file, so nothing changes from the user's point of view.		2023-07-27 21:56:32 +04:00
