MySQL Storage Engines: Overview, Differences, and Interview Guidance

MySQL’s pluggable storage‑engine architecture lets each table use a specific engine, with InnoDB (the default in MySQL 8.x) offering row‑level locking, ACID transactions, foreign‑key support, crash recovery, MVCC and a buffer pool, while MyISAM provides only table‑level locking, no transactions, and is suited mainly for read‑intensive workloads lacking recovery requirements.
