> SliceQueryFilter has some very useful new features like ability to specify a composite column prefix to group by and specify a limit of groups to return.
> This is very useful if for example I have a wide row with columns prefixed by timestamp and I want to retrieve the latest columns, but I don't know the column names. Say I have a row
> {{row -> (t1, c1), (t1, c2)... (t1, cn) ... (t0,c1) ... etc}}
> Query slice range (t1,) group by prefix (1) limit (1)
> As a more general question, is the Thrift interface going to be kept up-to-date with the feature changes or will it be left behind (a mistake IMO) ?
