> [sync] Do not store pipe infomation after drop
> ----------------------------------------------
>
> Key: IOTDB-4628
> URL: https://issues.apache.org/jira/browse/IOTDB-4628
> Project: Apache IoTDB
> Issue Type: Improvement
> Reporter: yanze chen
> Assignee: yanze chen
> Priority: Major
>
> In old version, pipe infomation will be stored even if pipe has been dropped.
> There are two advantages to not storing pipe infomation after drop can.
> # Support rollback logic in procedure better. If failed to create pipe, drop
> directlt.
> # Other modules(e.g.Trigger) do the same thing. Doing so can keep the
> semantics consistent in IoTDB.
