Query tuning Insights

What is Query tuning?

Query tuning is the process of optimizing database queries to improve their performance. This typically involves analyzing query execution plans, identifying bottlenecks (e.g., full table scans, inefficient joins), and modifying the query or the database schema (e.g., adding indexes) to reduce resource consumption and execution time. Common techniques include rewriting queries, adding appropriate indexes, updating database statistics, and partitioning tables.
