资讯评论 - BeetlSQL 3.23.11 发布，SQL 查询性能提高 40%~300% - OSCHINA

性能优化:SQL查询后结果映射到Java Entity，性能至少提供40%，有些场景提高300%
更好的支持动态表，向操作普通POJO一样操作动态表,比使用Map更方便
代码生成支持指定父类
SQ防火墙的性能部分优化

性能优化结果:

查询	优化前（ops/ms)	优化后(ops/ms)	mybatis
beetlsqlExecuteJdbc	222	318	/
beetlsqlExecuteTemplate	198	268	44
beetlsqlFile	191	266	41
beetlsqlGetAll	5	13	4
beetlsqlLambdaQuery	150	196	9
beetlsqlPageQuery	128	159	17
beetlsqlSelectById	186	259	43

性能优化办法:

优化了Java反射调用，使用生成字节码直接调用，参考BeanASMPerfTest.java, myasm 性能非常接近手写的代码（直接调用）,远远高于反射调用，也高于使用其他字节码增强工具reflectAsm

 * BeanASMPerfTest.direct(直接调用)         thrpt    3  3597282.120 ± 2031070.301  ops/ms
 * BeanASMPerfTest.myasm (字节码调用)       thrpt    3  1889599.007 ± 1013919.850  ops/ms
 * BeanASMPerfTest.propertySet(反射调用)    thrpt    3     3462.095 ±    2748.584  ops/ms
 * BeanASMPerfTest.reflectAsm(字节码工具)   thrpt    3    18580.151 ±   13286.590  ops/ms

动态表支持：方便的通过BeetlSQL访问动态表

		SQLManager sqlManager = getSQLManager();
		int max = 5;
		//创建5个表
		for(int i=0;i<max;i++){
			String dml="create table my_table"+i+"(id int NOT NULL"
				+ ",name varchar(20)"
				+ ",PRIMARY KEY (`id`)"
				+ ") ";
			sqlManager.executeUpdate(new SQLReady(dml));
		}

        // 配置加载类，使用默认的BassEntity，也可以使用任何类作为父类,比如MyOfficeEntity
		DynamicEntityLoader<BaseEntity> dynamicEntityLoader = new DynamicEntityLoader(sqlManager);

		for(int i=0;i<max;i++){
            //Class<? extends MyOfficeEntity> c = dynamicEntityLoader.getDynamicEntity("my_table"+i,MyOfficeEntity.class);
			Class<? extends BaseEntity> c = dynamicEntityLoader.getDynamicEntity("my_table"+i);
			long  count = sqlManager.allCount(c);
			System.out.println(count);
		}


		for(int i=0;i<max;i++){
			Class<? extends BaseEntity> c = dynamicEntityLoader.getDynamicEntity("my_table"+i);
			BaseEntity obj = c.newInstance();
			obj.setValue("id",1);
			obj.setValue("name","hello");
			sqlManager.insert(obj);
		}
