  • 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); 		}

    BeetlSQL 自主研发自 2015 年，目标是提供开发高效，维护高效，运行高效的数据访问框架，它适用范围广，定制性强，写起数据库访问代码特别顺滑，不亚于 MyBatis。你不想写 SQL 也好，或者想更好地写 SQL 也好，BeetlSQL 都能满足这要求，目前支持的数据库如下

  • 传统数据库：MySQL (包括支持 MySQL 协议的各种数据库), MariaDB ,Oralce ,Postgres (包括支持 Postgres 协议的各种数据库), DB2 , SQL Server ，H2 , SQLite , Derby ，神通，达梦，华为高斯，人大金仓，PolarDB，GBase8s，GreatSQL 等
  • 大数据：HBase，ClickHouse，Cassandar，Hive,GreenPlum
  • 物联网时序数据库：Machbase，TD-Engine，IotDB
  • SQL 查询引擎：Drill,Presto，Druid
  • 内存数据库：ignite，CouchBase
