Salmon

Salmon, an easy framework which support distributed db system.

Self-developed and controllable distributed database framework

• Simplify dao layer development, more controllable and flexible than mybatis
• Support regular transactions, cross-database transactions based on two-phase protocol commit and retry mechanism
• Support multiple strategies for sub-database sub-table
• Support mainstream databases such as jdbc and oracle
• Seamless connection with spring

Inquire

@Autowired
@Mapper(file = "mapper1", database = DataBase.JDBC)
public Salmon salmon;

//Inquire
Map map = (Map) salmon.select("query2").execute("101a7cb6-0aff-11ec-b26b-88e9fe840b9a");

//Inquire
Map map = (Map) salmon.select("query").execute(Collections.singletonMap("id", "101a7cb6-0aff-11ec-b26b-88e9fe840b9a"));

Insert

// insert
Map param3 = Maps.newConcurrentMap();
param3.put("id", UUID.randomUUID().toString());
param3.put("namespace", "test");
param3.put("path", "spring.port");
param3.put("value", "9093");
salmon.insert("insert").execute(param);

Affairs

//Open the transaction

salmon.startTrans();
Map param = Maps.newConcurrentMap();
param.put("id", UUID.randomUUID().toString());
param.put("namespace", "test");
param.put("path", "spring.port");
param.put("value", "9091");
salmon.insertTrans("insert").execute(param);

Map param2 = Maps.newConcurrentMap();
param2.put("id", UUID.randomUUID().toString());
param2.put("namespace", "test");
param2.put("path", "spring.port");
param2.put("value", "9092");
salmon.insertTrans("insert").execute(param2);

salmon.commitTrans();
