Re: Move Row, RowInputFormat to core package

There is no good reason why only Scala developers should have access to this class. If we also want to read CSV files into Row objects, Row must be in core. Am 28/11/16 um 14:37 schrieb Anton Solovev: What do you think about moving "Row" not into core module, but into Scala module? -Ori

Syinchwun, Can you maybe share more technical details such as design docs/papers about this approach, or is it confidential? It sounds interesting but the details make a difference (i.e. partial boundaries - bookkeeping). Paris > On 28 Nov 2016, at 13:01, liuxinchun wrote: > > Dear Aljoscha

Re: Move Row, RowInputFormat to core package

2016-11-28 Thread Aljoscha Krettek
If we move it to core, we have to untangle it from Scala, as Timo said. The reason is that we would like to remove Scala from any user facing API maven packages and if we had it in core everyone would have to suffix maven packages with the Scala version. On Fri, 25 Nov 2016 at 16:47 Anton Solovev

Re: Window's Checkpoint problem

2016-11-28 Thread Aljoscha Krettek
Hi, this is indeed a bug (though I would see it more as a feature since I think using the Checkpointed interface there can indeed be problematic, as Till pointed out). The problem is that the Scala Wrapper functions have to implement all kinds of interfaces so that they can forward to the wrapped f

Hi 时某人, I think you've found an inconsistency in Flink's windowing API (but it's the same in the Java API). Handling operator state in the context of windows is a little bit delicate because you could have multiple windows in flight, though. I've pulled Aljoscha in this thread who is more familiar
