Introduction
In this article, we will see how developers can break down information silos for their teams and business by replicating data across multiple systems. First, we will review why developers will replicate data and considerations for the cloud. Second, we will prepare for war with the replicators. Then we will examine the architecture of Postgres and MySQL and how their commit logs enable us to make exact copies of the data. Finally, we will connect Debezium to Postgres for a complete data replication solution.
Introduction to Data Replication
Data replication is the process of moving data between different database systems for various business use cases. In a typical SaaS (Software As A Service) application, data is stored in an operational database such as MySQL, PostgreSQL, Oracle, etc. There are other database systems such as data warehouses and search systems built for specialized use cases. Moving data between these systems is known as data replication.
