Chapter 1. Introduction

Tungsten Replicator™ is an open source replication engine supporting a variety of different extractor and applier modules. Data can be extracted from MySQL, Oracle and Amazon RDS, and applied to a variety of transactional stores, NoSQL stores such as and datawarehouse stores. For a full list of supported sources and targets, see Table 1.1, “Supported Extractors” and Table 1.2, “Supported Appliers” below

During replication, Tungsten Replication assigns data a unique global transaction ID, and enables flexible statement and/or row-based replication of data. This enables data to be exchanged between different databases and different database versions. During replication, information can be filtered and modified, and deployment can be between on-premise or cloud-based databases. For performance, Tungsten Replicator™ provides support for parallel replication, and advanced topologies such as fan-in, star and multi-master, and can be used efficiently in cross-site deployments.

Tungsten Replicator™ is the core foundation for the Continuent Tungsten clustering solution for HA, DR and geographically distributed solutions.
