Greetings,
Currently, it seems that the user can delete all data and timeseries: delete timeseries root.*; But this sql cann't delete all related storage groups. In addition, such an approach would be more time-consuming than simply deleting specified storage groups. So I believe it's better for `delete storage group FullPath` command to support wildcard, which can be regarded as `delete storage group <prefixPath>` For example, all sgs and data can be deleted by one sql efficiently: delete storage group root.*; This sql is useful for some users in many scenarios, such as system cleanup during continuous testing. I have implemented this feature and created a PR[1], you can take a review if you are interested in it. [1] https://github.com/apache/iotdb/pull/1881 Best:) -------- Xinyu Tan
