Subhobrata Dey commented on FLINK-2678: --------------------------------------- Hello Till, I was checking the implementation of PrimitiveArrayTypeInfo.java ( which is the TypeInformation implementation of 1-d array ) The tasks mention about multidimensional arrays. By multidimensional do you intend to restrict the solution to a particular dimension like 2-d or 3-d? or do you have some elegant solution to make the dimension dynamic? Kindly let me know because I plan to implement the solution. > DataSet API does not support multi-dimensional arrays as keys > ------------------------------------------------------------- > > Key: FLINK-2678 > URL: https://issues.apache.org/jira/browse/FLINK-2678 > Project: Flink > Issue Type: Wish > Components: DataSet API > Reporter: Till Rohrmann > Assignee: Subhobrata Dey > Priority: Minor > > The DataSet API does not support grouping/sorting on field which are > multi-dimensional arrays.
