Hi again!
I am currently trying to make use of the filtering by query predicate example
which was discussed in another thread here ("Build UDF project"), see below:
*connect feed UserFeed to dataset EmpDataset WHERE
testlib#wordDetector(fname) = TRUE;*
start feed UserFeed;
. using the wordDetector UDF found here:
https://github.com/idleft/asterix-udf-template/blob/master/src/main/java/org/apache/asterix/external/library/WordInListFunction.java
However, the output type of this UDF, as defined in library_descriptor.xml is
"ABOOLEAN". Will it still store the entire record (InputRecordType) in the
EmpDataset, or only the boolean value? And, if I would like to use the records
which pass the filtering in wordDetector as input to another UDF, would I need
to change the output type of the UDF? If so, the check
"testlib#wordDetector(fname) = TRUE;*" will not work anymore, due to the output
being an entire record instead of only a boolean.
I appreciate your help!
Best regards,
Sandra
