stream目录磁盘空间占用高 #28741

Something isn't working

麻烦截图一下该目录下的明细: |
收到。 |
本身由于你的流计算比较多,任务也多,所以计算量比较大,在中间状态中可能会有这么大的空间占用。 |
最近升级版本 我把流计算删掉了 删了好像也没有释放空间 意思是用DELETE_MARK释放空间吗 |
请按照这个操作来清理流。 这个流文件的删除是流自己控制的。 请在最新版本再观察 |

版本3.3.3
一共24条流计算,SQL都差不多,如下
create stream hr_stream24 into s_t_1669_compressor_current_2 subtable(concat('new_', tname)) as select _wstart, _wend, (avg(
value) * 220 * 600) energy from d_1669_compressor_current_2 partition by tbname tname interval(10m);
才运行了4个月不到,vnode下stream目录已经生成100G的文件,是否正常,如何优化
