Description: Provides an interface to the 'Apache DataSketches'
    (<https://datasketches.apache.org/>) library of streaming algorithms for
    approximate analytics on data too large to hold or process exactly.
    Sketches are compact, mergeable summaries built in a single pass over a
    stream that answer queries such as approximate distinct counts, quantiles
    and ranks, frequent items and point-frequency estimates, weighted sampling,
    and set membership with mathematically proven error bounds. Implements
    Karnin-Lang-Liberty (KLL), Relative Error
    Quantiles (REQ), t-Digest, HyperLogLog (HLL), Compressed Probabilistic
    Counting (CPC), Theta, Frequent Items, Count-Min, Array of Doubles,
    Variance Optimal (VarOpt), Exact and Bounded Probabilistic
    Proportional-to-Size (EBPPS), and Bloom filter sketches, with native
    serialization for interoperability with other 'Apache DataSketches'
    implementations.
