When a user requests for feed then there will be two parallel threads involved in fetching the user feeds to optimize for latency. FUN FACT : In this talk , Dikang Gu, a software engineer at Instagram core infra team has mentioned about how they use Cassandra to serve critical usecases, high scalability requirements, and some pain points.

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.

It’s been clear for a while that software designed explicitly for the data center environment will increasingly want/need to make different design trade-offs to e.g. general-purpose systems software that you might install on your own machines. The desire for CPU efficiency and lower latencies is easy to understand. Enter Google!

A site reliability engineer, or SRE, is a role that that encompasses aspects of both software engineering and operations/infrastructure. The term site reliability engineering first came into existence at Google in 2003 when a site reliability team was created. At that time, the team was made up of software engineers.

Two failure modes we focus on are a service becoming slower (increase in response latency) or a service failing outright (returning errors). The criticality score is combined with a safety score and experiment weight (failure experiments, then latency, than failure inducing latency) to produce the final prioritization score.

And, FMA instructions often have lower latency than a multiply followed by an add instruction. On the Xbox 360 CPU the latency and throughput of FMA was the same as for fmul or fadd so using an FMA instead of an fmul followed by a dependent fadd would halve the latency. Emulating FMA.
