Package: data.sketches Title: Probabilistic Streaming Data Sketches Version: 0.1.0 Authors@R: c( person("Pedro", "Baltazar", email = "pedrobtz@gmail.com", role = c("aut", "cre", "cph")), person("The Apache Software Foundation", role = "ctb", comment = "Author of bundled Apache DataSketches C++ code"), person("Stephan", "Brumme", role = "ctb", comment = "Author of bundled xxhash64.h code"), person("Austin", "Appleby", role = "ctb", comment = "Author of bundled public-domain MurmurHash3 code"), person(c("Sean", "Eron"), "Anderson", role = "ctb", comment = "Author of bundled public-domain bit-hack code used in ceiling_power_of_2.hpp") ) Description: Provides an interface to the 'Apache DataSketches' () 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.
