- 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
