Summary: Optimize value filter query
Key: IOTDB-849
URL: https://issues.apache.org/jira/browse/IOTDB-849
Project: Apache IoTDB
Issue Type: Improvement
Components: Core/Engine
Reporter: Yuan Tian
Assignee: Yuan Tian
Now, while doing query with value filter, we won't use the time filter
condition in filter to unpack the chunk to pages. For exmaple:
select s1 from root.sg1.d1 where time > 0 and time < 10 and s1 > 0 and s1 < 9;
We will get an AndFilter as valueFilter whose left node is 'time > 0 and time <
10' and right node is 's1 > 0 and s1 < 9'. While unpacking chunk, we only use
timeFilter(which is null in this case) to filter the page. However, timeFilter
is null in this case, so we need to unpack all the page data in this chunk
whatever it is really satisfied.
