----------------------------------
https://github.com/apache/iotdb/pull/11124
> Fix incorrect output of UDF with multiple inputs
> ------------------------------------------------
>
> Key: IOTDB-6149
> URL: https://issues.apache.org/jira/browse/IOTDB-6149
> Project: Apache IoTDB
> Issue Type: Bug
> Reporter: liaolanyu
> Assignee: liaolanyu
> Priority: Major
> Attachments: udf.jar
>
>
> How to reproduce:
> # Create a function with UDF that uses SlidingTimeWinodw AccessStrategy and
> takes multiple expressions as input.
> # Run a query using this function with multiple inputs like: select func(s1,
> s2) from root.sg
> # See if the ouput is correct.
> You can use the attached jar as the udf lib.
> Inserting data into two series is enough to reproduce this issue.
> You can register the UDF and run the SQL as follows:
> CREATE FUNCTION best_fit_retrieval AS
> 'org.apache.iotdb.udf.cisdi.tendency.CisdiUDTFBestFitRetrievalWithText';
> select
> best_fit_retrieval(s1,'cycleTime'='10','preValue'='0.41335068807341324','preTime'='0','afterValue'='null',
>
> 'afterTime'='0','startTime'='1','endTime'='10','isCalcFitValue'='true','isCollectorNull'='false','interpolationType'='Linear')
> from root.test.unitTest;
