Specifically, we will dive into the architecture that powers search capabilities for studio applications at Netflix. We must quickly surface the most stand-out highlights from the titles available on our service in the form of images and videos in the member experience. First, we must provide the content that will bring them joy.

If we were to select the most important MySQL setting, if we were given a freshly installed MySQL or Percona Server for MySQL and could only tune a single MySQL variable, which one would it be? MySQL comes pre-configured to be conservative instead of making the most of the resources available in the server. Why is that?

Some opinions claim that “Benchmarks are meaningless”, “benchmarks are irrelevant” or “benchmarks are nothing like your real applications” However for others “Benchmarks matter,” as they “account for the processing architecture and speed, memory, storage subsystems and the database engine.”

In this post I'll look at the Linux kernel page table isolation (KPTI) patches that workaround Meltdown: what overheads to expect, and ways to tune them. I then analyzed performance during the benchmark ([active benchmarking]), and used other benchmarks to confirm findings. Much of my testing was on Linux 4.14.11

Distributing accounts across the infrastructure is an architectural decision, as a given account often has similar usage patterns, languages, and sizes for their Lambda functions. A cold start occurs when there’s no instance of the requested Lambda function available. After each execution, AWS Lambda puts the instance to sleep.

Rather than listing the concepts, function calls, etc, available in Citus, which frankly is a bit boring, I’m going to explore scaling out a database system starting with a single host. And now, execute the benchmark: -- execute the following on the coordinator node pgbench -c 20 -j 3 -T 60 -P 3 pgbench The results are not pretty.

Since “peak performance” for the processor is two (512-bit SIMD) FMA instructions per cycle, any instructions that are not FMA instructions subtract directly from the available peak performance. of the “adjusted peak performance”, there is no longer a significant upside to performance tuning.

Many of these systems support I/O ordering with a stable media cache and subsequently combine and/or split I/O requests across available subsystem resources to complete the storing to physical media. For specific information on I/O tuning and balancing, you will find more details in the following document.
