遇上的严重问题
Mysqlsession 无法释放(现在HBT有此问题),
解决: Mysqlsession.unbindMycatSession();
印象中会出现心跳检测会从mycatsession取Mysqlsession造成null异常,再次判断一次是否已经unbind?
数据投进队列后,由于多线程poll,造成提早返回EOF给客户端
解决:只使用一个队列处理
使用MyCommand实现,socket在某次正常返回数据时候后,关闭了,没有异常
原因还没查明,使用BackendIOTaskWithResultSet实现没有此问题

如何合拼多线程接收的数据源,
使用队列合拼带有标记数据源字段的row?
投进队列中执行的拷贝,使用的介质:
byte[] ByteBuffer MappedBytebuffer
假设一个row只有128bytes却占用了8192bytes的ByteBuffer,
byte[]是否造成GC压力?
批处理:进入队列的单元是row,是否可以多个row?
无锁队列?环形队列?使用MappedByteBuffer构建环形队列?
直到使用MySQLCommand.onBackendResponse的时候再替换Task?lazy new object
从currMycatSession.getMySQLSession的时候是否绑定MySQLSession MycatSession与MySQLSession的关系
