It optimizes for memory usage over CPU usage. It implements all the HyperLogLog optimizations introduced in the HyperLogLog++ paper (http://goo.gl/Z5Sqgu). Some notable features include:\n\n* marshaling so you can serialize to your datastore\n* extra space savings by only using 5 bits per register when possible\n* built-in non-streaming murmur3 implementation for fast hashing of input data\n\n## Usage\n\n    h := hllpp.New()\n\n    h.Add([]byte(\"barclay\"))\n    h.Add([]byte(\"reginald\"))\n    h.Add([]byte(\"barclay\"))\n    h.Add([]byte(\"broccoli\"))\n\n    fmt.Println(h.Count())\n    // Output: 3\n\nSee the godocs for documentation and more examples.\n\n### SEO\n\nThis package is a go or golang implementation of HyperLogLog or HyperLogLog++. It doesn't show up when you search for golang hyperloglog, so I am repeating the words golang hyperloglog in the README. golang hyperloglog.\n","funding_links":[],"categories":[],"sub_categories":[],"project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fretailnext%2Fhllpp","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fretailnext%2Fhllpp","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fretailnext%2Fhllpp/lists"}
