Replay: Flush based on buffer size

[bruno-garcia]

Problem Statement

The server won't accept replays larger than 10 MB

Solution Brainstorm

Make sure to flush after time interval or certain size. In case we have more than 10 MB we need to discard the event and emit client report.

This issue has gone three weeks without activity. In another week, I will close it.

But! If you comment or otherwise update it, I will reset the clock, and if you label it Status: Backlog or Status: In Progress, I will leave it alone ... forever!

I wrote #8315 which stops replay when the event buffer exceeds 20MB. I think this is the safe approach here...?
