Target customers: users of ApsaraDB RDS for MySQL 5.6, 5.7, and 8.0. Features released: major updates of the AliSQL kernel version 20191015 include: 1. AliSQL 8.0 provides transparent data encryption (TDE) to encrypt and decrypt data files in real time. Data files are encrypted before they are written to disks and decrypted before they are read to the memory. 2. AliSQL 8.0 supports ResultSet responses from DML statements. 3. AliSQL 5.7 and 8.0 allow you to collect performance data and save the data as local formatted text files. File polling is used to retain the latest 5-second interval data. 4. AliSQL 5.7 and 8.0 can convert the engine from MEMORY to InnoDB when the global variable rds_force_memory_to_innodb is set to ON. 5. AliSQL 5.6 and 5.7 provide the log rotation feature to uniquely rename the CSV files and create new files for slow logs. You can execute the SHOW VARIABLES LIKE '%rotate_log_table%'; statement to check whether slow log rotation is enabled. 6. AliSQL 5.6 uses the SM4 algorithm to implement TDE.
