Consider Introducing PSMDB for MongoDB Management

[hackerwins]

What would you like to be added:

Currently, Yorkie server operates with MongoDB as its primary database, and api.yorkie.dev cluster runs MongoDB on K8s using bitnami/mongodb-sharded chart. This chart simplifies the installation of MongoDB Sharded Clusters, but the management tasks such as data backups, restorations, and vertical & horizontal scaling require manual configurations.

At the recent Daangn Tech meetup, PSMDB (Percona Server for MongoDB) was presented as a potential solution that offers built-in capabilities for creating Sharded Clusters along with features for vertical and horizontal scaling, as well as backup and restoration.

I propose that we evaluate PSMDB for potential adoption to streamline our database operations. The evaluation should focus on:

• Database updates
• Vertical & horizontal scaling
• Backup & restoration: S3 backup storage, backup scheduling, and management of backup lists

PSMDB Installation:

• https://docs.percona.com/percona-operator-for-mongodb/minikube.html
• https://docs.percona.com/percona-operator-for-mongodb/eks.html

Why is this needed:

Adopting PSMDB could significantly enhance our operational efficiency and reduce the complexity involved in managing our MongoDB deployment. This transition will help us maintain a more robust and scalable environment for Yorkie server.
