Developers were told to use ORMs and prepared statements to avoid SQL injections for a long time now. By doing so, they effectively separate instructions (the semantics of the SQL query) from the data. Modern languages and frameworks often also abstract away the need to write raw queries, offering high-level interfaces around our database models. Unfortunately, that's not enough to thwart away SQL injections once and for all, as these APIs can still present subtle bugs or nuances in their design

Database sharding is a powerful technique employed to manage large databases more effectively. It involves partitioning a large database into smaller, more manageable parts, known as shards. The term "shard" signifies a small fragment of a whole, aptly describing this method of breaking down a large database into smaller, more manageable pieces. Sharding is often applied to databases for several reasons, including improving query performance , facilitating data organization , and enhancing scala

Before Percona Server for MongoDB 4.4 (PSMDB), the best practice to create an index was doing it in a rolling manner. Many folks used to create directly on Primary, resulting in the first index being created successfully on Primary and then replicated to Secondary nodes. Starting from PSMDB 4.4, there was a new parameter commitQuorum introduced in the createIndex command.

Scalability testing is an approach to non-functional software testing that checks how well applications and infrastructure perform under increased or decreased workload conditions. The organization can optimize infrastructure costs and create the best user experience by determining server-side robustness and client-side degradation. It makes it easier to fix defects and ensure software applications' flawless functioning.
