MySQL in the last 2 years … Copyright © 2022,
Oracle and/or its affiliates Even more features...

20 Invisible column MySQL in the last 2 years … MySQL in the last 2 years … • Invisible Columns (since 8.0.23) o Hidden to queries, but can be accessed explicitly by naming the column names explicitly mysql> CREATE TABLE t1 (col1 INT, col2 INT INVISIBLE); mysql> INSERT INTO t1 (col1, col2) VALUES(1, 2), (3, 4); mysql> SELECT * FROM t1; +------+ | col1| +------+ | 1 | | 3 | +------+ mysql> SELECT col1, col2 FROM t1; +------+------+ | col1 | col2 | +------+------+ | 1 | 2 | | 3 | 4 | +------+------+

21 Invisible column & Primary Key – Generated Invisible Primary Keys (GIPK) MySQL in the last 2 years … MySQL in the last 2 years … • The MySQL server can now automatically adds a generated invisible primary key (GIPK) to an InnoDB table that is created without an explicit primary key (since 8.0.30) • GIPK mode is controlled by the sql_generate_invisible_primary_key server system variable • GIPK mode, a primary key is added to a table by the server, the column and key name is always my_row_id • Good if you planned to use MySQL Replication (ReplicaSet) or MySQL innoDB Cluster

22 Indexing & Primary Key problem MySQL in the last 2 years … MySQL in the last 2 years … • Indexes can now be built simultaneously instead of serially (since 8.0.27) o innodb_ddl_threads / innod_ddl_buffer_size / innodb_parallel_read_threads o Possibility to build multiple indexes for a table in the same alter statement in parallel • Primary Key (PK) problem o PK are required for good performance and are mandated for MySQL InnoDB Cluster o Reality is that lots of applications/users don’t create PKs o …and they are not allowed to create one • Solutions o You can force usage of PK with sql_require_primary_key=on (since 8.0.13) o You can use invisible columns and add a primary key • How to finding tables without PKs: SELECT tables.table_schema, tables.table_name, tables.engine FROM information_schema.tables LEFT JOIN (SELECT table_schema, table_name FROM information_schema.statistics GROUP BY table_schema, table_name, index_name HAVING SUM(CASE WHEN non_unique = 0 AND nullable != 'YES' then 1 else 0 end ) = count(*) ) puks ON tables.table_schema = puks.table_schema AND tables.table_name = puks.table_name WHERE puks.table_name IS null AND tables.table_type = 'BASE TABLE' AND Engine='InnoDB';

23 • Supports dump and load of instances, schemas and tables o Parallel loading of tables or table chunks o Progress state tracking o Resume and reset capability o Can add invisible columns with primary keys to tables o Splits larger tables in smaller chunks (reads 2GB/s+) o Loads chunks in parallel (writes 200MB/s+) • Support for native storage in OCI Object Storage • Recommended tool to migrate data to MySQL Database Services • Commands o util.dumpInstance() dump an entire database instance, including users o util.dumpSchemas() dump a set of schemas o util.dumpTables() dump a set of schemas o util.loadDump() load a dump into a target database https://dev.mysql.com/blog-archive/mysql-shell-dump-load-part-2-benchmarks/ MySQL 8.0 Shell: Load & Dump utilities MySQL in the last 2 years … MySQL in the last 2 years …

28 • Our wording has changed since 8.0.26 (still ongoing) • We kept the long task of removing offensive words in our code (commands, tables, documentation...) • Master/Slave → Source/Replica, Whitelist/Blacklist → Allowlists/Blocklist • Don‘t get confused about „depreciations“ warnings, MySQL Replication is still supported Replication: Master/Slave is now Source/Replica MySQL in the last 2 years … MySQL in the last 2 years …

29 New authentication methods since 8.0.27 MySQL in the last 2 years … MySQL in the last 2 years … • MySQL Enterprise Edition extend Community Authentication and provides ready to use external authentication modules to easily integrate existing security o Supports Linux PAM, Windows Active Directory, native LDAP… • MySQL 8.0 now support o Kerberos  Authentication using Kerberos requires a KDC server  Applications and MySQL servers are able to mutually authenticate users and MySQL services o FIDO (Fast IDentity Online)  Enables authentication to MySQL Server using devices such as smart cards, security keys, and biometric readers  Because authentication can occur other than by providing a password, FIDO enables password less authentication  Device authentication is often used in conjunction with password authentication

30 Multifactor Authentication (MFA) since 8.0.27 MySQL in the last 2 years … MySQL in the last 2 years … • New system variable – authentication_policy o Controls how many authentication factors can be used and types of authentication permitted for each factor • Specify MFA using CREATE USER and ALTER USER o Add/Modify/Drop authentication methods for new/existing accounts o New authentication factors stored in mysql.user table in USER_ATTRIBUTES column • Accounts can now have up to three authentication values o Client programs have now --password1, --password2, and --password3 options
