Thanks yeah ! (tuple sketch and not theta as you said!). I have another question please I looked at the tuple sketch I looked at: https://datasketches.apache.org/api/java/snapshot/apidocs/org/apache/datasketches/tuple/aninteger/IntegerSummary.Mode.html and I see possible values of mode are: Sum, Min, Max, AlwaysOne so I don't see there is 'Variance'. So is tuple sketch not supporting variance out of the box? I looked at druid and I see it does support variance sketch https://druid.apache.org/docs/latest/development/extensions-core/datasketches-tuple.html#variance-values-for-each-column does this means the following: Tuple sketches do not support variance out of the box, but as druid supports it on top of the tuple sketches it's probably going to be possible for me to add similar implementation on top of DataSketches TupleSketches ?
