conversations.db initially was used to keep an index of email conversations (e.g. the threaded views typically found in most email readers nowadays). But today it also helps for most use-cases where we need to keep track of messages across mailboxes (e.g. if you have two copies of an email in two mailboxes, you'll see that reflected in conversations.db). It confusingly is still named conversations.db for historic reasons. But for any recent (v3) Cyrus IMAP installation, including Xapian and JMAP, it's a very critical piece in the puzzle.
