Provides the hlld package that implements a client library for the
HyperLogLog daemon (HLLD). HyperLogLogs provide
an extremely efficient method of cardinality estimation. The client library
supports pipelining for extremely high throughput.
The full documentation is available on Godoc.
Below is a simple example of usage
// 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")
}
