I'm finding it increasingly challenging to integrate new features into my application because the current database schema is rigid and complex. Modifying it to accommodate new data structures is provi

Consider increasing RAM, CPU cores, or using faster storage (e.g., SSDs) if hardware is the limiting factor.

Track CPU, memory, and disk I/O during the workload execution to identify resource bottlenecks.

Consider creating indexes that cover multiple columns used together in query predicates.

Use database performance monitoring tools or query execution plans to find columns that would benefit from indexing.

Use `EXPLAIN` or `EXPLAIN ANALYZE` to identify bottlenecks in the query execution and optimize accordingly.

Refactor queries to use more efficient join strategies, avoid `SELECT *`, and utilize window functions where appropriate.

Create indexes on columns frequently used in WHERE clauses, JOIN conditions, and ORDER BY clauses.

Ensure efficient connection management to reduce overhead for frequent query executions.

Adjust parameters like `work_mem` (PostgreSQL) or `sort_buffer_size` (MySQL) to allow for larger sorts and hash joins in memory.

Increase shared_buffers (PostgreSQL) or innodb_buffer_pool_size (MySQL) to cache more data in memory.
