If we had an ID for each streaming session then distributed tracing could easily reconstruct session failure by providing service topology, retry and error tags, and latency measurements for all service calls. Using simple lookup indices in Cassandra gives us the ability to maintain acceptable read latencies while doing heavy writes.

A Cassandra database cluster had switched to Ubuntu and noticed write latency increased by over 30%. top(1) showed that only the Cassandra database was consuming CPU. In 2019 myself and others tested kvm-clock and found it was only about 20% slower than tsc. These can be invisible to top(8).

Distributed tracing describes the act of following a transaction through all participating applications (tiers) and sub-systems, such as databases. In 2019, the OpenCensus and OpenTracing projects merged into what we now know as OpenTelemetry. Distributed computing didn’t start with the rise of microservices.

Similarly for this guide MySQL can be swapped for a mySQL based databases such as MariaDB.

As is exactly the same with PostgreSQL for system choice a 2 socket system is optimal for MySQL OLTP performance.

Estimated Input Latency tells us if we are hitting that threshold, and ideally, it should be below 50ms. Designed for the modern web, it responds to actual congestion, rather than packet loss like TCP does, it is significantly faster , with higher throughput and lower latency — and the algorithm works differently.
