Less "mark" in MySQL benchmarking
13 hours ago, smalldatum

My goal for the year is more time learning math and less time running MySQL benchmarks. I haven't done serious benchmarks for more than 12 months. It was a great experience but I want to learn new things. MySQL 8.0.14 has been released with fixes for a serious bug I found via the insert benchmark. I won't confirm whether it has been fixed. I hope someone else does.My tests and methodology are described in posts for sysbench, linkbench and the insert benchmark.  I hope the upstream distros (MySQL...

Richard Yen: The Curious Case of Split WAL Files
15 hours ago, postgresql

Introduction I’ve come across this scenario maybe twice in the past eight years of using Streaming Replication in Postgres: replication on a standby refuses to proceed because a WAL file has already been removed from the primary server, so it executes Plan B by attempting to fetch the relevant WAL file using restore_command (assuming that archiving is set up and working properly), but upon replay of that fetched file, we hear another croak: “No such file or directory.” Huh? The file is there? ls...

How do you secure and monitor all those containers?   To address these challenges, you can use a service mesh: software that helps you orchestrate, secure, and collect telemetry ...
