uses a sketch to aggregate the data?4) if it is the case then is it guaranteed
that the merged sketches are immutable? otherwise wrapping the union with locks
is not enough.
I hope my questions make more sense now.
Thanks,Eshcar

My name is Eshcar Hillel from Oath research. I'm currently working with Lee
Rhodes on committing a new concurrent implementation of the theta sketch to the
sketches-core library.I was wondering whether this implementation can help
boost the union operation that is applied to multiple
