Specific sink behaviour based on tuple key

[Alexis Gendronneau]

Hi all,

I am looking to customize a sink behaviour based on tuple key.

My goal is to have each sink partition to write to a specific output.

My job will be something like :

input -> keyBy() -> outputSink

This output should be something like './base/path/keyValue/....'.

But I was not able to find where key value is stored, could you help me to go the right way :)

Hi,

The Key is not available directly to a user function? You would have to use within that function the same code that you use for your KeySelector.

Best,

Aljoscha
