------------------------------
Summary: Optimize 'delete from' query when deleting multiple
timeseries data
Key: IOTDB-852
URL: https://issues.apache.org/jira/browse/IOTDB-852
Project: Apache IoTDB
Issue Type: Improvement
Components: Core/Engine
Reporter: Wei Shao
Assignee: Wei Shao
When deleting data from multiple timeseries, a successful deletion will leave a
record in mods file for each timeseries.
Suppose we executing "delete from root.sg1.d1.*" and d1 contains N
measurements, we would write at most N lines of records in each mods file,
which may cause performance issue if N is very large.
