Hello @kejang, did you manage to resolve this issue? I seem to be having the same problem and don't know how to rectify it.

@LSparkzwz you might want to consider the [frequent items sketch](https://github.com/apache/datasketches-python/blob/main/jupyter/FrequentItemsSketch.ipynb) for approximate top-k queries on streams.

@geonove I have assigned you.
