Hi Devs, I want to use UDF to process the Tweets that I got from the feed, and I met following two questions. Hope you guys can help me or point me to the right documentation.
1. How to install UDF on instance running from Eclipse+AsterixHyracksIntegrationUtil? Website only mentioned how to install with Managix. I am wondering if there is a way for me to install it on instance running in Eclipse, which is easier for debugging. 2. Implementation of UDF I found several UDFs in asterixdb/asterix-external-data/src/test/java/org/apache/asterix/external/library, like SumFunction, ParseTweetFunction. I assume if I want to implement new UDF, it needs to implement IExternalScalarFunction interface and to be put under the same directory? I also found 'aggregate' and 'unnest' type which is not implemented yet. Just out of curiosity, what is the difference between them? Thanks in advance! :) Best, Xikui
