I'd like to revive this thread highlighting another advantage of using the DataSketches library which I came across recently. Besides being well maintained, the library provides binary representation compatibility across implementations, which makes it interoperable with external systems. An example usage might be a Spark pipeline generating intermediate data sketches before writing into Pinot. Pinot can serve queries with complex filters and eventually merge/intersect these sketches to produce estimates. This can already be achieved in Pinot for cardinality estimation using ThetaSketch functions 👍 . I think a quantile implementation such as KLL and a Frequent Items sketch from this library would be great additions to complete the picture. I'd be happy to give it a hand if we can get a consensus on including them. @mayankshriv please let me know what you think. -- This is an automated message from the Apache Git Service.
