Understanding Linux IOWait

Percona

I have seen many Linux Performance engineers looking at the “IOWait” portion of CPU usage as something to indicate whenever the system is I/O-bound. In this blog post, I will explain why this approach is unreliable and what better indicators you can use. Let’s start by running a little experiment – generating heavy I/O usage on the system: sysbench --threads=8 --time=0 --max-requests=0 fileio --file-num=1 --file-total-size=10G --file-io-mode=sync --file-extra-flags=direct

Proof of Concept: Horizontal Write Scaling for MySQL With Kubernetes Operator

Percona

Historically MySQL is great in horizontal READ scale. The scaling, in that case, is offered by the different number of Replica nodes, no matter if using standard asynchronous replication or synchronous replication. However, those solutions do not offer the same level of scaling for writes operation. Why? Because the solutions still rely on writing in one single node that works as Primary.

MySQL replies with success or error based on supplied credentials, and the time required for the verification is almost the same in either case. Hence, an attacker can launch a brute force attack against a MySQL user account at a rapid rate and can try many different passwords.
