InfluxDB Cluster - An Open-Source Distributed Time Series Database, Open Source Alternative to InfluxDB Enterprise

An Open-Source, Distributed, Time Series Database

InfluxDB Cluster is an open source time series database with no external dependencies. It's useful for recording metrics, events, and performing analytics.

InfluxDB Cluster is inspired by InfluxDB Enterprise, InfluxDB v1.8.10 and InfluxDB v0.11.1, aiming to replace InfluxDB Enterprise.

InfluxDB Cluster is easy to maintain, and can be updated in real time with upstream InfluxDB 1.x.

Features

  • Built-in HTTP API so you don't have to write any server side code to get up and running.
  • Data can be tagged, allowing very flexible querying.
  • SQL-like query language.
  • Clustering is supported out of the box, so that you can scale horizontally to handle your data. Clustering is currently in production state.
  • Simple to install and manage, and fast to get data in and out.
  • It aims to answer queries in real-time. That means every data point is indexed as it comes in and is immediately available in queries that should return in < 100ms.

Clustering

Note: The clustering of InfluxDB Cluster is exactly the same as that of InfluxDB Enterprise.

Installation

We recommend installing InfluxDB Cluster using one of the pre-built releases.

Complete the following steps to install an InfluxDB Cluster in your own environment:

  1. Install InfluxDB Cluster meta nodes
  2. Install InfluxDB Cluster data nodes

Note: The installation of InfluxDB Cluster is exactly the same as that of InfluxDB Enterprise.

Docker Quickstart

Download docker-compose.yml, then start 3 meta nodes and 2 data nodes by docker-compose:

docker-compose up -d
docker exec -it influxdb-meta-01 bash
influxd-ctl add-meta influxdb-meta-01:8091
influxd-ctl add-meta influxdb-meta-02:8091
influxd-ctl add-meta influxdb-meta-03:8091
influxd-ctl add-data influxdb-data-01:8088
influxd-ctl add-data influxdb-data-02:8088
influxd-ctl show

Stop and remove them when they are no longer in use:

docker-compose down -v

Getting Started

Create your first database

curl -XPOST "http://influxdb-data-01:8086/query" --data-urlencode "q=CREATE DATABASE mydb"

Insert some data

curl -XPOST "http://influxdb-data-01:8086/write?db=mydb" \
-d 'cpu,host=server01,region=uswest load=42 1434055562000000000'

curl -XPOST "http://influxdb-data-02:8086/write?db=mydb&consistency=all" \
-d 'cpu,host=server02,region=uswest load=78 1434055562000000000'

curl -XPOST "http://influxdb-data-02:8086/write?db=mydb&consistency=quorum" \
-d 'cpu,host=server03,region=useast load=15.4 1434055562000000000'

Note: consistency=[any,one,quorum,all] sets the write consistency for the point. consistency is one if you do not specify consistency. See the Insert some data / Write consistency for detailed descriptions of each consistency option.

Query for the data

curl -G "http://influxdb-data-02:8086/query?pretty=true" --data-urlencode "db=mydb" \
--data-urlencode "q=SELECT * FROM cpu WHERE host='server01' AND time < now() - 1d"

Analyze the data

curl -G "http://influxdb-data-02:8086/query?pretty=true" --data-urlencode "db=mydb" \
--data-urlencode "q=SELECT mean(load) FROM cpu WHERE region='uswest'"
