Hi Matthias, Thanks. But yes, I am comparing map with that.map … the comment is probably for the previous variable name.
I can use String, Int, Enum, Long type keys in the Key that I send in the Query getKvState … but the moment I introduce a TreeMap, even though it contains a simple one entry String, String, it doesn’t work … Thanks, Sandeep > On 23-Mar-2021, at 7:00 PM, Matthias Pohl <matth...@ververica.com> wrote: > > Hi Sandeep, > the equals method does not compare the this.map with that.map but > that.dimensions. ...at least in your commented out code.
