What is Laravel advanced database indexing strategy for high-performance applications?

Advanced indexing strategy optimizes query performance by selecting appropriate single, composite, and covering indexes based on query patterns.

In high-performance Laravel applications, indexing is not just about adding indexes but designing them based on query patterns. Composite indexes improve multi-column filtering, while covering indexes allow queries to be satisfied entirely from the index without hitting the table. However, over-indexing slows writes. Laravel migrations allow precise control over index creation, but real optimization depends on analyzing query execution plans using database tools.
