-----------------------------------
h2. 测试环境
IOTDB：私有云 16核32G 1T的硬盘，默认配置，根据日志看到写入内存分配=2993055334
benchmark：周测配置aligned_seq_config.properties、unseq_config.properties
h2. 测试结果
|| ||aligned_seq_config.properties||unseq_config.properties||

> Project: Apache IoTDB
> Issue Type: Improvement
> Reporter: Jialin Qiao
> Assignee: yanze chen
> Priority: Major
> Labels: pull-request-available
>
> Currently, we have a parameter called storage_group_report_threshold, which
> means when a storage group report its memory usage, it should accumulate a
> memory change of this number.
> If this parameter is too small, may report frequently, which may decrease the
> insertion performance.
> If this parameter is too large, may report not in time, which may cause OOM.
>
> We need to change this parameter according to the memory allocated for
> writing.
>
> (1) remove storage_group_report_threshold
> (2) Add a new parameter write_memory_vriation_report_proportion
>
> To rel/0.13 and master
