Synchronise your data between MySQL and MongoDB

The document discusses synchronizing data between MySQL and MongoDB using Tungsten Replicator. Tungsten Replicator allows data to be replicated from a MySQL database to MongoDB in near real-time. The document provides examples of data being inserted and updated in MySQL, and then appearing in MongoDB through the replication process. It also discusses security features and how to install Tungsten Replicator for basic master-slave replication between MySQL and MongoDB databases.

What is MongoDB • • • • • • • ©Continuent 2013 Tuesday, October 15, 13 A non-relational database A document-oriented database Schema-free Open source High performance Scalable Developer-friendly (sort of) 10 10
What is MongoDB good for? • • • Storing large amount of unrelated data • IT IS NOT a drop-in replacement for a relational database ©Continuent 2013 Tuesday, October 15, 13 Data that can't be constrained in a schema Complement to relational data 11 11

MySQL to MongoDB basics ©Continuent 2013 Tuesday, October 15, 13 22 22
Replication from MySQL to MongoDB • • • • • • • ©Continuent 2013 Tuesday, October 15, 13 Requires ROW-based-replication Replication happens by table There is no consolidation into "documents" DDL commands are ignored Statement commands are ignored Column names become document attributes enum and set columns are converted to strings 23 23
First example of replication # MySQL create schema oneschema; use oneschema ; create table myfirst( num int not null primary key, dt datetime, ts timestamp, going enum('yes', 'no')); # MongoDB > show dbs local 0.078125GB test 0.203125GB tungsten_mysql2mongodb 0.203125GB # NOTICE: no "oneschema" ©Continuent 2013 Tuesday, October 15, 13 24 24
