Hi there, With 10+ years of experience working with large-scale MySQL/MariaDB systems, I’ve optimized databases with hundreds of millions of rows — delivering measurable improvements in query speed and overall performance. Even with indexes already in place, I can dig deeper to uncover inefficiencies: analyzing your query execution plans, identifying index misuse or redundancy, and restructuring queries or schema where necessary. I also look at partitioning strategies, covering indexes, and caching mechanisms to ensure SELECT queries run at peak speed. For one recent client, I reduced average SELECT execution time from 3.2 seconds to under 200ms on a 65M-row dataset without altering application logic — purely through indexing strategy refinement and query optimization. I can review your current setup, run a performance audit, and apply optimizations tailored to your workload so you see immediate, tangible improvements. Let’s make your 43M-row database run like it’s tiny.
