Database gateway

In this section, we will go through real real-world examples featuring database gateway. We will first start by reviewing the deployment architecture, followed by the configuration and testing for both of ShardingSphere's clients – Proxy and JDBC.

The deployment architecture

In this case, the underlying database adopts PostgreSQL, deployed with the read/write splitting architecture of one host and two secondaries. The upper database layer adopts a hybrid deployment solution of ShardingSphere-Proxy and ShardingSphere-JDBC. Based on the distributed governing capabilities provided by Cluster mode, you can easily modify cluster metadata online and synchronize the data to proxy and JDBC. Proxy can use the ShardingSphere built-in DistSQL to achieve traffic control operations (including circuit breaker) and disable the secondary database.

Figure 12.18 illustrates the typical deployment architecture, including both proxy and JDBC, and primary and...
