ShardingSphere-JDBC 81 Apache ShardingSphere document, v5.2.0 Usage Import Maven Dependency ThreadLocal to manage sharding key values for mandatory routing. A sharding value can be added by programming to the HintManager that takes effect only within the current thread. Apache ShardingSphere can marks for mandatory routing. A primary database routing mark can be added to HintManager through programming, and this value is valid only in the current thread. Apache ShardingSphere can also route the

In addition to the programming method, Apache ShardingSphere also plans to cite Hint through special notation in SQL, so that using decorator merger. Parse Engine Compared to other programming languages, SQL is relatively simple, but it is still a complete set of programming language, so there is no essential difference between configuration method, which is suitable for the scenarios requiring dynamic configuration through programming.
