Github user aljoscha commented on the pull request: https://github.com/apache/flink/pull/1429#issuecomment-163680178 This looks good. :+1: Can you also integrate the support for Scala, i.e. extract it from #1237 My only concern is that it introduces yet another instance where TypeInformation is shipped to the cluster. I think we should tackle the problem at some point. Maybe generate the code on the client and ship the code as a string. Then use Janino to just compile it to a final class. --- If your project is set up for it, you can reply to this email and have your reply appear on GitHub as well.

[FLINK-3097] [table] Add support for custom functions in Table API
As described in FLINK-3097, this PR implements the possibility of adding
custom row functions for the Table API.
In the tests you can find some examples how custom functions can look like:
```
table.select("TRIM(f0)")
table.select("SYSTEM_TIME()")
table.select("SUBSTRING(SUBSTRING(f0, 2, 5), 0, 1)")
table.select("SUBSTRING(f0, 1), SUBSTRING(f0, 2, 5)")
```
The Scala Table API is not supported yet, since I'm still waiting for #1237.
You can merge this pull request into a Git repository by running:
$ git pull https://github.com/twalthr/flink TableApiCustomFunctions
Alternatively you can review and apply these changes as the patch at:
