In that scenario, the system would need to deal with the data propagation latency directly, for example, by use of timeouts or client-originated update tracking mechanisms. We started seeing increased response latencies and leader servers running at dangerously high utilization. The query rate in this test is set to 1K requests/second.

While there is plenty of well-documented benefits to using a connection pooler, there are some arguments to be made against using one: Introducing a middleware in the communication inevitably introduces some latency. A middleware becomes a single point of failure. They are well worth the added configuration and maintenance effort.

So where in a CI/CD pipeline do we put performance testing? The easy answer is: right after a change is deployed to an integration or testing environment. Typically, performance testing should happen at the same time as integration and acceptance testing. Network latency will affect performance testing.

Low-latency Queries To avoid downloading all of the fact data from s3 in a spark executor and then dropping it, we analyzed our query patterns and figured out that there is a way to only access the data that we are interested in. Another learning is that we should have invested early into a robust testing framework.
