# go-hlld

Provides the `hlld` package that implements a client library for the

[HyperLogLog daemon](https://github.com/armon/hlld) (HLLD). HyperLogLogs provide

an extremely efficient method of cardinality estimation. The client library

supports pipelining for extremely high throughput.

Documentation

=============

The full documentation is available on [Godoc](http://godoc.org/github.com/armon/go-hlld).

Example

=======

Below is a simple example of usage

```go

// Create a client

client, err := hlld.Dial("hlld-server:1234")

if err != nil {

    panic("could not dial")

}

// Create a new set, custom precision

createCommand, err := hlld.NewCreateCommand("foo")

if err != nil {

    panic("failed to make command")

}

// Start the command

future, err := client.Execute(createCommand)

if err != nil {

    panic("failed to make command")

}

// Wait for the command to finish

if err := future.Error(); err != nil {

    panic("command failed")

}

// Check the result

ok, err := createCommand.Result()

if !ok || err != nil {

    panic("failed to make set")

}

```
