  • 5. How to build Handler Socket Plug-in

  • 7. mysql> install plugin handlersocket soname handlersocket.so;
  • 8. Handler Socket configuration parameter
  • 9. • handlersocket_port (default = 9998)• handlersocket_port_wr (default = 9999)• handlersocket_threads (default = 16, min = 1, max = 3000)• handlersocket_threads_wr (default = 1, min = 1, max = 3000)• handlersocket_sndbuf (default = 0, min = 0, max = 1677216)• handlersocket_rcvbuf (default = 0, min = 0, max = 1677216)• handlersocket_readsize (default = 0, min = 0, max = 1677216)• handlersocket_wrlock_timeout (default = 12, min = 0, max = 3600)• handlersocket_timeout (default = 300, min = 30, max = 3600)• open_files_limit = 65535• innodb_buffer_pool_size =8G
  • 10. Handler Socket java client program
  • 11. Dependent Packageshs4j-0.1.jarlog4j-1.2.8.jarslf4j-api-1.5.6.jarslf4j-log4j12-1.3.0.jar
  • 12. Java Key methods(1)• public HSClientImpl(InetSocketAddress inetSocketAddress, int poolSize)• public IndexSession openIndexSession(String dbname, String tableName,String indexName, String[] columns)• public IndexSession openIndexSession(int indexId, String dbname, String tableName, String indexName, String[] columns)
  • 13. Java Key methods(2)• public boolean insert(String[] values)• public int delete(String[] keys)• public int delete(String[] keys, FindOperator operator)• public int delete(String[] keys, FindOperator operator, int limit,int offset)• public int update(String[] keys, String[] values, FindOperator operator)
  • 14. Java Key methods(3)• public int update(String[] keys, String[] values, FindOperator operator,int limit, int offset)• public ResultSet find(String[] keys)• public ResultSet find(String[] keys, FindOperator operator, int limit,int offset)• public ModifyStatement createStatement()
  • 15. Create the MYSQL tablescreate table mt_data( guid varchar(18) not null, orgid int(9) not null, tabid int(9) not null, name varchar(128) not null, IsDeleted char(1) not null, createtime datetime not null, modifytime datetime not null, .... primary key(guid,orgid)) ENGINE=InnoDB CHARSET=utf8;
  • 16. Java example code fragment• HSClient hsClient = new HSClientImpl(new InetSocketAddress("10.224.56.188", 9999), connectionPoolSize);• final String[] columns = { "guid", "orgid", "tabid", "name","IsDeleted", "createtime", "modifytime", "value0","value1", "value2", "value3", "value4", "value5", "value6","value7", "value8", "value9", "value10", "value11","value12", "value13", "value14", "value15" };IndexSession session = hsClient.openIndexSession("meetingdb","mt_data", "PRIMARY", columns);• Bind values final String[] values3 = new String[9]; values3[0] = guid; values3[1] = "1"; ……• session.insert(values)• hsClient.shutdown();
  • 17. Best Practice for java client
  • 18. • HSClient is thread-safe, so you must use it as SINGLETON object in your application.• Open index is an expensive operation, so reuse an opened index id as much as possible.• IndexSession is thread-safe,so please reuse an opened IndexSession as much as possible.• Use IndexSession rather than HSClient• Use ModifyStatement to insert/update data
  • 19. ModifyStatement example codeModifyStatement stmt = this.session.createStatement();stmt.setInt(1, 0);stmt.setString(2, "dennis");stmt.setInt(4, 27);stmt.setString(5, "2010-11-28 13:24:00");stmt.update(keys, FindOperator.EQ);
