What are some effective MySQL indexing strategies?
Effective MySQL indexing strategies include using primary keys, unique indexes, and composite indexes to optimize query performance.
Can you explain how composite indexes work?
Composite indexes are indexes on multiple columns. They help speed up queries that filter on those columns together.
When should I avoid using indexes?
Avoid using indexes on columns with low cardinality or on frequently updated columns, as they can slow down write operations.
How do I analyze the performance of my indexes?
You can use the EXPLAIN
statement in MySQL to analyze how your queries utilize indexes and identify potential improvements.
