Sam b839493fea PERF: Limit new messages in suggested for PMs

Sam 0aed2533ac Revert unread optimisation, has too many edge cases 2017-05-26 09:04:13 -04:00
Sam 29fac1ac18 PERF: improve performance of unread queries
Figuring out what unread topics a user has is a very expensive
operation over time.

Users can easily accumulate 10s of thousands of tracking state rows
(1 for every topic they ever visit)

When figuring out what a user has that is unread we need to join
the tracking state records to the topic table. This can very quickly
lead to cases where you need to scan through the entire topic table.

This commit optimises it so we always keep track of the "first" date
a user has unread topics. Then we can easily filter out all earlier
topics from the join.

We use pg functions, instead of nested queries here to assist the
planner.

Sam Saffron bc75010b20 FEATURE: suggested messages for messages
FEATURE: clicking envelope takes you to inbox

Suggested messages works somewhat like suggested topics.

- New show up first (in either group inbox or inbox)
- Then unread (in either group inbox or inbox)
- Finally "related" which are messages with same participants as the current pm.

Sam 03ea0bfe22 FEATURE: allow users to archive messages
Messages are now in 3 buckets

- Inbox for all new messages
- Sent for all sent messages
- Archive for all messages you are done with

You can select messages from your Inbox or Sent and move them to your Archive,
you can move messages out of your Archive similarly

Similar concept applied to group messages, except that archiving and unarchiving
will apply to all group members
