MariaDB Alerts
The webinar is started with showing the workstation where a three node MariaDB Cluster and a Stash backup configuration were running. Next, Speaker talked about a values.yaml file which was responsible for deploying different group of MariaDB alerts. Different database related alerts like MySQLInstanceDown, MySQLServiceDown were deployed and fired by manually shutting down the MariaDB servers running on cluster.
Afterwards, Speaker talked about the galera replication latency alert which was triggered by running a script that created a load on MariaDB Clutser. The alert status was initially updated to PENDING and after a minute the alert was FIRING.
Later, KubeDB Custom Resource alerts were deployed to illustrate alerts that cause under different failure scenarios of KubeDB CRs. To give an idea, A OpsReq was created with expected failing configuration which activated the Custom Resource Alerts.
In conclusion of first part, MariaDB Stash alerts were deployed and tested by creating a backup session with bad secret data. The alert fired succesfully upon the failure of backup session.
MariaDB Multi-Tenancy
In the second part of the webinar speaker discussed about multi tenancy support for Mariadb, where several databases schemas were creted using kubeDB’s upcoming feature Schema Manager. Creating database, altering them, initializing with script and restoring snapshot using Schemas were demonstrated. User management and security concerns regarding multi tenancy implementation were also discussed in a brief.
