1. TONIGHT Solomon Chang proudly presents: MySQL Clustering Welcome to the UUASC LA Chapter

2. NDB Cluster High Availability* Shared-Nothing Architecture Redundancy

3. Server Requirements Any machine that can run MySQL

4. Server Requirements Any machine that can run MySQL Non-Microsoft Operating System

5. Server Requirements Any machine that can run MySQL Non-Microsoft Operating System A buttload of RAM

7. Types of Nodes Data Nodes  ndbd Management Nodes  ndb_mgmd API Nodes  mysqld  ndb_mgm

9. Bits and Pieces Partition (AKA Fragment)  A portion of a table Replica  A copy of a Partition Node Group  A collection of individual data nodes

15. Security of Nodes

16. Authentication: None

17. Security of Nodes Authentication: None Encryption: None

18. Security of Nodes Authentication: None Encryption: None Management and Data Nodes are very trusting as to who or what connects to them

21. Transports Gigabit Ethernet  Bare recommended minimum SCI  Scalable Coherent Interconnect Infiniband

22. Performance Primary Key are hashes

23. Performance Primary Key are hashes  Hashed values determine which rows are distributed to which data nodes

24. Performance Primary Key are hashes  Hashed values determine which rows are distributed to which data nodes Pushdown

25. Performance Primary Key are hashes  Hashed values determine which rows are distributed to which data nodes Pushdown  Spreading query work across multiple data nodes  set engine_condition_pushdown = 1

26. Data Node Setup In /etc/my.cnf: [MYSQLD] ndbcluster ndb-connectstring=10.0.0.152 [MYSQL_CLUSTER] ndb-connectstring=10.0.0.152

27. Management Node Setup config.ini sections  [ndbd]  [ndb_mgmd]  [mysqld]

28. Management Node Setup config.ini sections  [ndbd]  [ndb_mgmd]  [mysqld] Sections can be blank

29. Management Node Setup config.ini sections  [ndbd]  [ndb_mgmd]  [mysqld] Sections can be blank There can be multiple instances of a section

30. SQL Node Setup Just like the Data Node Setup In /etc/my.cnf: [MYSQLD] ndbcluster ndb-connectstring=10.0.0.152 [MYSQL_CLUSTER] ndb-connectstring=10.0.0.152

31. SQL Node Setup The Management Node already knows this is a SQL node from its config.ini file

32. Enough Talking It's showtime

33. Cluster Replication Cluster replication is exactly the same as regular MySQL replication, with the exception of the Binary Log Injection Thread.

35. Backup and Restoration Why would a fault-tolerant, completely redundant system would ever need to have a backup for restoring data?

36. Disk-Based NDB Cluster

37. HA Caveat SQL Nodes
