Hi, alex
The current UDAnF we looking at is something about funnel chart, you can see the detail at this link <https://www.excelcampus.com/charts/excel-funnel-chart/>. The situation is if we directly use SQL to do the funnel chart is very complex and time consuming, and the plan for us is to do something like UDAnF which process a bunch of tuples at one time when overing the data to produce intermediate results. The UDAnf approach works very well under vertica, and can we use default impala UDF/UDAF to imitate it? Plus, the contributing thing is always on our radar^_^ 2016-12-20 5:28 GMT+08:00 Alex Behm <[email protected]>: > Hi! > > good question.
