-- Add a table that keeps track of a list of users who should, upon their next
|
|
-- sync request, receive presence for all currently online users that they are
|
|
-- "interested" in.
|
|
|
|
-- The motivation for a DB table over an in-memory list is so that this list
|
|
-- can be added to and retrieved from by any worker. Specifically, we don't
|
|
-- want to duplicate work across multiple sync workers.
|

CREATE TABLE IF NOT EXISTS users_to_send_full_presence_to(
|
|
-- The user ID to send full presence to.
|
|
user_id TEXT PRIMARY KEY,
|
|
-- A presence stream ID token - the current presence stream token when the row was last upserted.
|
|
-- If a user calls /sync and this token is part of the update they're to receive, we also include
|
|
-- full user presence in the response.
|
|
-- This allows multiple devices for a user to receive full presence whenever they next call /sync.
