# 问题
- 我们在生产环境进行删除(按时间删除,横向删除测点)后,生成了mods文件,但一直不执行tsfile的合并,造成删除后数据文件大小不降反增,请问如何解决?
# 尝试方法
执行 merge、full merge命令
等待自动执行合并tsfile操作(至今未执行)
# 运行情况

**设备数量:** 100万
**物理量数量:** 1000万
**文件大小:** 30+GB
**版本:** 0.13.4
**上线时间:** 2024年9月初上线,稳定运行3月+
Contributor guide
Research direction
Start with the DELETE TIMESERIES operation and the merge and full merge commands described in the report. Reproduce the mods and tsfile behavior at a smaller scale, then inspect why automatic merging is not triggered; done means the cause is identified and deletion reliably reaches the expected merge behavior.
