bigqueue's Introduction

bigqueue Build Status Go Report Card MIT license GoDoc codecov golangci

bigqueue provides embedded, fast and persistent queue written in pure Go using memory mapped (mmap) files.

Installation

go get github.com/grandecola/bigqueue

Requirements

  • Only works for linux and darwin OS
  • Only works on Little Endian architecture

Usage

Create or open a bigqueue:

bq, err := bigqueue.NewBigQueue("path/to/queue")
defer bq.Close()

Bigqueue persists the data of the queue in multiple Arenas. Each Arena is a file on disk that is mapped into memory (RAM) using mmap syscall. Default size of each Arena is set to 128MB. It is possible to create a bigqueue with custom Arena size:

bq, err := bigqueue.NewBigQueue("path/to/queue", bigqueue.SetArenaSize(4*1024))
defer bq.Close()

Bigqueue also allows setting up the maximum possible memory that it can use. By default, the maximum memory is set to [3 x Arena Size].

bq, err := bigqueue.NewBigQueue("path/to/queue", bigqueue.SetArenaSize(4*1024), bigqueue.SetMaxInMemArenas(10))
defer bq.Close()

In this case, bigqueue will never allocate more memory than 4KB*10=40KB. This memory is above and beyond the memory used in buffers for copying data.

Write to bigqueue:

err := bq.Enqueue([]byte("elem"))   // size = 1

Read from bigqueue:

elem, err := bq.Peek()        // size = 1
err := bq.Dequeue()           // size = 0

Check whether bigqueue has non zero elements:

isEmpty := bq.IsEmpty()

Benchmarks

Benchmarks are run on a Lenovo P52s laptop (4x2 core, i7, 15.4GB RAM) ubuntu 18.10 AMI, 64 bit machine.

Note: Before running benchmarks ulimit and vm.max_map_count parameters should be adjusted using below commands:

ulimit -n 50000
echo 262144 > /proc/sys/vm/max_map_count
