This document discusses the HandlerSocket plugin for MySQL. It provides a Java client for HandlerSocket that allows high-performance operations on MySQL databases. Code examples are given showing how to open a connection, execute commands, and retrieve results. Performance test results are also presented showing HandlerSocket outperforming standard JDBC access in terms of query response times. System monitoring outputs are displayed relating to disk I/O, context switching, and CPU usage.

HandlerSocket hs = new HandlerSocket();
try{
(Java)
System.out.println("open connection.");
hs.open(host, port);
System.out.println("open index.");
hs.command().openIndex(id, db, table, index, fieldList);
System.out.println("operations.");
for(int i = 0 ; i <= size ; i++){
if(i != 0 && i % loop == 0){
System.out.println("tcommand size : " + hs.getCommandSize() + "byte");
List<HandlerSocketResult> results = hs.execute();
System.out.println("tresult size : " + hs.getCurrentResponseSize() + "byte");
if(verbose){
System.out.println("result.");
for(HandlerSocketResult result : results){
System.out.println("t" + result.toString());
}
}

}
}finally{
System.out.println("close connection.");
