Reporting Using MySQL Multi-Source Replication
How can we do real time reporting using MySQL when data is spread across different MySQL instances?
We can achieve this using Multi-Source replication.
Multi-Source replication is used for consolidating data from different MySQL instances.
There are two major use cases for Multi-Source replication:
(1) Backup at a single place for data spread across different MySQL instances. (2) Real Time Reporting - the capability to do complex joins across tables which were otherwise present in different Instances - say a join across Orders & Invoices Tables.
This session would present different ways of achieving Multi-Source replication in MySQL 5.5, the pros & cons of each approach, solutions to failure scenarios i.e. what if a MySQL instance we were replicating from fails, how would failover take place.
This session would also talk about the Relay Log & its power to make failover very easy.
