> 问题描述：
> DEVICE_NUMBER=50
> SENSOR_NUMBER=200000, 共1000w个序列。
> CLIENT_NUMBER=10
> 写入顺序数据，90%写入，10% last 查询。
> MAX_HEAP_SIZE="20G"
> MAX_DIRECT_MEMORY_SIZE="6G"
> 其余参数默认，OOM
> !image-2022-04-24-17-31-36-557.png!
> jprofiler监控（bm的写入和查询已经kill掉）：
> !image-2022-04-24-17-31-59-799.png!
> 昊男帮忙定位，执行只有写入，没有查询。无OOM。
> 猜测last 查询在这种场景下没有控制内存
> iotdb配置文件，bm配置文件见附件。
> 机器信息：8C32G * 2
> 192.168.130.1 iotdb
