Hi, What is the recommended / most performant way to keep track of read status of message conversations in a multimodel database such as ArangoDB?
To give an example: There are 4 users logged in in the system: A, B, C and D Users A, C and D are starting a chat session and start sending messages to eachother. At one point, user C has to leave for a meeting, but users A and D are still sending messages. Later on, user C logs in again in the system and has to be informed if and how many messages he missed from users A and/or D. Obviously this is a simplified example as in reality there are multiple chat sessions going on between multiple people all the time, while people can enter or leave at any time. Of course there are several ways to implement this, but what interests me is the most performant way to do this. Should I just create several collections (chats, messages, users) and store id's of related documents, similar to how this is / can be done in a relational db? E.g. each chat message is stored in the "messages" collection and includes the id of the chat session it belongs to (from "chats" collection) as well as the userid of the sender Or would it be more performant to create edges between those collections (instead of storing id's inside each document), possibly in combination with edge attributes? Or should I use a real graph to get the best performance? The most difficult part for me is - in terms of performance - how to keep track of which message is read by which user and to retrieve the (number of) unread messages since the last "mark as read" action for each user.
