After tuning our store for Pushy’s needs, it has been on autopilot since, appropriately scaling and serving our requests with very low latency. This delicate balance led to us doing a deep evaluation of many instance types and performance tuning options. We run this asynchronously to avoid any event loop blocking due to these calls.

Challenges At Netflix, temporal data is continuously generated and utilized, whether from user interactions like video-play events, asset impressions, or complex micro-service network activities. We sometimes raise this limit for backfilling historical data, but it is tuned back down for regular write operations.

Next, we’ll look at how to set up servers and clients (that’s the hard part unless you’re using a content delivery network (CDN)). Using just a few (but still more than one), however, could nicely balance congestion growth with better performance, especially on high-speed networks. This is true, but only to a relatively limited extent.
