This allows tracking of histograms in a composable way such that accurate error can be reasoned about. + +## License + +[Apache 2.0](LICENSE) + + + +## Usage Example + +```go +package main + +import ( + "fmt" + + "github.com/openhistogram/circonusllhist" +) + +func main() { + //Create a new histogram + h := circonusllhist.New() + + //Insert value 123, three times + if err := h.RecordValues(123, 3); err != nil { + panic(err) + } + + //Insert 1x10^1 + if err := h.RecordIntScale(1, 1); err != nil { + panic(err) + } + + //Print the count of samples stored in the histogram + fmt.Printf("%d\n", h.Count()) + + //Print the sum of all samples + fmt.Printf("%f\n", h.ApproxSum()) +} +``` + +### Usage Without Lookup Tables + +By default, bi-level sparse lookup tables are used in this OpenHistogram implementation to improve insertion time by about 20%. However, the size of these tables ranges from a minimum of ~0.5KiB to a maximum of ~130KiB. While usage nearing the theoretical maximum is unlikely, as the lookup tables are kept as sparse tables, normal usage will be above the minimum. For applications where insertion time is not the most important factor and memory efficiency is, especially when datasets contain large numbers of individual histograms, opting out of the lookup tables is an appropriate choice. Generate new histograms without lookup tables like: + +```go +package main + +import "github.com/openhistogram/circonusllhist" + +func main() { + //Create a new histogram without lookup tables + h := circonusllhist.New(circonusllhist.NoLookup()) + // ... +} +``` + +#### Notes on Serialization + +When intentionally working without lookup tables, care must be taken to correctly serialize and deserialize the histogram data. The following example creates a histogram without lookup tables, serializes and deserializes it manually while never allocating any excess memory: + +```go +package main + +import ( + "bytes" + "fmt" + + "github.com/openhistogram/circonusllhist" +) + +func main() { + // create a new histogram without lookup tables + h := circonusllhist.New(circonusllhist.NoLookup()) + if err := h.RecordValue(1.2); err != nil { + panic(err) + } + + // serialize the histogram + var buf bytes.Buffer + if err := h.Serialize(&buf); err != nil { + panic(err) + } + + // deserialize into a new histogram + h2, err := circonusllhist.DeserializeWithOptions(&buf, circonusllhist.NoLookup()) + if err != nil { + panic(err) + } + + // the two histograms are equal + fmt.Println(h.Equals(h2)) +} +``` + +While the example above works cleanly when manual (de)serialization is required, a different approach is needed when implicitly (de)serializing histograms into a JSON format. The following example creates a histogram without lookup tables, serializes and deserializes it implicitly using Go's JSON library, ensuring no excess memory allocations occur: + +```go +package main + +import ( + "encoding/json" + "fmt" + + "github.com/openhistogram/circonusllhist" +) + +func main() { + // create a new histogram without lookup tables + h := circonusllhist.New(circonusllhist.NoLookup()) + if err := h.RecordValue(1.2); err != nil { + panic(err) + } + + // serialize the histogram + data, err := json.Marshal(h) + if err != nil { + panic(err) + } + + // deserialize into a new histogram + var wrapper2 circonusllhist.HistogramWithoutLookups + if err := json.Unmarshal(data, &wrapper2); err != nil { + panic(err) + } + h2 := wrapper2.Histogram() + + // the two histograms are equal + fmt.Println(h.Equals(h2)) +} +``` + +Once the `circonusllhist.HistogramWithoutLookups` wrapper has been used as a deserialization target, the underlying histogram may be extracted with the `Histogram()` method. It is also possible to extract the histogram while allocating memory for lookup tables if necessary with the `HistogramWithLookups()` method. diff --git a/vendor/github.com/openhistogram/circonusllhist/circonusllhist.go b/vendor/github.com/openhistogram/circonusllhist/circonusllhist.go new file mode 100644 index 00000000000..0f630792281 --- /dev/null +++ b/vendor/github.com/openhistogram/circonusllhist/circonusllhist.go @@ -0,0 +1,1150 @@ +// Copyright 2016, Circonus, Inc.
