You’re building with Spring Boot — but is your app truly optimized, or merely functional?
Master the 9 Pillars Every Engineer Must Know
Understanding Reference Equality, Value Equality, hashCode(), Lombok, and Records
For any serious Java developer — especially one working with Spring Boot — understanding Maven is non negotiable. Maven is more than just a build tool; it’s ...

Programming paradigms are different styles or approaches to solving problems using code. They define how you structure and write programs.
💡 Whether you’re just starting with databases or you’re optimizing complex analytics pipelines, knowing the right SQL terms — and the lingo used by pros — ca...
A materialized view is a database object that stores the result of a query physically on disk, unlike regular views which execute the query every time they’r...
Partitioning is the process of dividing a large table or index into smaller, more manageable subsets (partitions) , while still treating them as a single tab...
When your application performs repetitive database operations — like inserting logs, validating data, or executing complex calculations — stored procedures a...
Joining multiple tables in a single query is common in relational databases, but excessive joins — especially on large datasets — can lead to:
Searching through large volumes of text using LIKE ‘%keyword%’ might get the job done on small tables — but it becomes a performance bottleneck as data grows...
When milliseconds matter, traditional disk based tables might not be fast enough. That’s where memory optimized tables come into play. Designed for ultra low...
Temporary tables are special tables that exist temporarily during a session or transaction. They are perfect for breaking down complex queries into manageabl...
Common Table Expressions (CTEs) are temporary result sets defined within the execution scope of a single SQL statement. CTEs are written using the WITH claus...
Not all databases are used the same way. Knowing whether your workload is transactional (OLTP) or analytical (OLAP) is essential for optimizing performance, ...
