Haven't a clue what they're talking about but at least we've got an explanation.Betfair wrote:We had multiple failovers of the Exchange Bet Stream on Saturday, which caused a full snapshot to be sent out to our other downstream applications. One of these applications ran out of memory when trying to process the snapshot, causing long garbage collection, and leading to bet placement failures. To mitigate such problems, we are currently in the process of aggressively reducing & tuning memory usage across both the Bet Stream and our downstream applications.

The api usually delivers deltas, changes since the last update. If you request a full snapshot when loading a new market, or they start streaming snapshots as it seems here, it's a hell of a lot bigger and it all goes bang.Derek27 wrote: ↑Wed Mar 08, 2023 12:46 amHaven't a clue what they're talking about but at least we've got an explanation.Betfair wrote:We had multiple failovers of the Exchange Bet Stream on Saturday, which caused a full snapshot to be sent out to our other downstream applications.

As an aside what I think is quite interesting is how it's worth leaving at least half an hour either side of a planned outage if you want to bet into typical markets. Looking at incomming network traffic around the last planned outage it's definately the case that people wind down early and then take a while to wind up again. The scale is Mb per 10mins.
