[MySQL Overview] Principle level: MySQL

Seven test points of Mysql:
1. Transaction: acid + transaction isolation level + redo undo OK
2. Index (speed up retrieval efficiency) OK
3. Slow query + SQL optimization: efficient single-table query + efficient multi-table query, optimize sql Statement
4. Master-slave replication (read-write separation + cold and hot separation, both require master-slave replication): master-slave replication is implemented based on binlog
5. mysql log system
6, mysql architecture and innodb architecture
7, mysql data type
8 , Distributed database CAP principle, Base principle, theoretical things, just remember
9. Other
important is the first 5, the most important is the first 3.
