After the upgrade of replicas to MariaDB 10.2 on RDS, Once replication is stopped manually through “call mysql.rds_stop_replication;” or replication failed due to some error.

Happy New Year. Here’s to 2018 being a great year in the open source database world. What is in store for us? Probably: MySQL 8.0 and MariaDB Server 10.3 as generally available. What will we see in the rest of the space? Clouds? All I know is that we move fast, and it’s going to be fun to see what unfolds.
The biggest news this week may not necessarily be database related; it focused on CPU security vulnerabilities and the potential slowdowns of your servers once the updates are applied. Please do read Meltdown and Spectre: CPU Security Vulnerabilities. Peter Zaitsev himself, got quoted in …
[Read more]Update: I included the results for when PCID is disabled, for comparison, as a worse case scenario.
After learning about Meltdown and Spectre, I waited patiently to get a fix from my OS vendor.

As it will be highly dependent on the hardware and workload, I decided of doing some test myself for the …
