Support for transactions: InnoDB is a storage engine that supports transactions, using row-level locking and multi-version concurrency control (MVCC) to achieve high concurrency transaction processing.
Foreign key constraints: InnoDB supports foreign key constraints to ensure data integrity and consistency, allowing for data relationships and operations at the table level.
Support row-level locking: InnoDB supports row-level locking to ensure data consistency and integrity during concurrent access, avoiding data competition and conflicts.
InnoDB supports various transaction isolation levels, including read uncommitted, read committed, repeatable read, and serializable, with the default isolation level being repeatable read.
Support for automatic recovery: InnoDB supports crash recovery and transaction log rollback, allowing for automatic recovery and repair in the event of database abnormal closure or crash.
Support data compression: InnoDB supports data compression, which can reduce storage space and improve performance by using compression algorithms.
Support for hot backup and recovery: InnoDB allows for backup and recovery operations to be carried out while the database is running, without the need to shut down the database service.
