For Pubsub services based on SQL or NoSQL databases, it should not be too hard to implement as ordering is most of time a part of API.
Note however, that some NoSQL databases only support a single index in the query, DynamoDB is such an example. You can apply post-filtering of course (kinda map-reduce, where filtering is "reduce"), but it may become inefficient depending on the query subset. That's just a thing to consider if you want to go too broad in your specification. _______________________________________________ Standards mailing list Info: https://mail.jabber.org/mailman/listinfo/standards Unsubscribe: standards-unsubscr...@xmpp.org _______________________________________________
