This article reveals eight powerful, lesser‑known MySQL 8.0 features—including window functions, descending indexes, generated columns, invisible indexes, optimizer hints, resource groups, LATERAL JOIN, and multi‑valued JSON indexes—showing how they dramatically improve query performance and simplify complex SQL tasks.
This article explains MySQL 8.0's new indexing features—including function indexes via virtual columns, Index Skip Scan for non‑leftmost predicates, descending indexes to avoid filesort, and invisible indexes for optimizer control—providing examples and usage guidelines.
This article explains MySQL 8.0's invisible index feature, outlines practical scenarios for its use, provides step‑by‑step SQL examples to create, hide, and test indexes, and shows how to enable the optimizer to consider invisible indexes for better performance and safer schema changes.
MySQL 8.0 introduces invisible indexes, allowing you to hide indexes from the optimizer while keeping them maintained, which serves as an index recycle bin for safe testing and removal, and the article explains their purpose, usage, and limitations with practical SQL examples.
