Welcome to the hs2client wiki!

Hs2Client is simple

1- Simple to use:

To use Hs2client, you only have to create a Hs2SessionFactoryImpl with a Hs2Conf, then you can open a session, no matter read only one or read/write one, to access mysql by using access methods that Hs2Session provides, e.g:

	val sessionFactory = new Hs2SessionFactoryImpl(Hs2Conf("host",connectionEncoding="GBK"))
	/*
	* open a readOnly session for read
	*/
	val session = sessionFactory.openSession(OpenIndexSpec("test", "dw", Array("id", "value")), true)
	try{
		println("result: "+session.get(Eq(),Array("13")).mkString(","))
	}
	finally{
		session.close
	}

2- Simple to extend:

You can extend hs2client by providing different parts of it, no matter Hs2SessionFactory, or Hs2Session, or even wrap Hs2client in a easier way.
