Summary:
- Puts events on a queue in memory and ensures they are sent in the order they were generated.
- Makes the caller (Sharing.ts) wait until changed records have been fetched from the DB, but allows it to continue after while remaining work happens asynchronously.
- Gathers all new webhook events into an array so they can be backed up to the queue on redis in a single command (in a future diff).
- Uses changes in isReady to determine event type, no more 'existed before'
The structure of the code has changed a lot, so I think the scope of the diff needs to stop here. Lots of work is still deferred in TODOs.
Test Plan: Updated existing test. Actually dropped testing of retry on failures and slowness because it no longer made sense to keep that as part of the current test, so a new test for that will be added in a future diff.
