  "Description": "Provides an interface to the 'Apache DataSketches'\n(<https://datasketches.apache.org/>) library of streaming\nalgorithms for approximate analytics on data too large to hold\nor process exactly. Sketches are compact, mergeable summaries\nbuilt in a single pass over a stream that answer queries such\nas approximate distinct counts, quantiles and ranks, frequent\nitems and point-frequency estimates, weighted sampling, and set\nmembership with mathematically proven error bounds. Implements\nKarnin-Lang-Liberty (KLL), Relative Error Quantiles (REQ),\nt-Digest, HyperLogLog (HLL), Compressed Probabilistic Counting\n(CPC), Theta, Frequent Items, Count-Min, Array of Doubles,\nVariance Optimal (VarOpt), Exact and Bounded Probabilistic\nProportional-to-Size (EBPPS), and Bloom filter sketches, with\nnative serialization for interoperability with other 'Apache\nDataSketches' implementations.",
