# chronus

chronus是基于influxdb1.7.x版本开发的分布式时序数据库，兼容官方的influxql。

## Features

- 完全兼容influxdb的influxql协议

- 高可用

- 水平线性扩展

- 最终一致性

- MPP架构：大规模并行处理

- 不依赖第三方服务

## Architecture



- meta server：负责元数据的存储和管理

- data server：负责数据的存储和管理，并向meta server获取元数据。所有涉及到元数据的修改，都会请求到meta server，由meta server执行修改，并同步给集群内所有的data server

## compile

- export GO111MODULE=on

- 需要梯子：export 

GOPROXY=https://goproxy.io

- mkdir -p workspace/src/github.com/angopher && export GOPATH=$PWD/workspace

- cd workspace/src/github.com/angopher

- git clone https://github.com/angopher/chronus.git && cd chronus

- 编译influxd： cd cmd/influxd && go build && cd -

- 编译metad：cd cmd/metad && go build

## run

配置启动meta server

- 生成默认配置文件：./metad config > metad.conf

- ./metad -config metad.conf

配置启动data server

- 生成默认配置文件 ./influxd config > influxd.conf

- ./influxd -config influxd.conf

## Getting Started

创建第一个数据库

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

写入数据

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

- curl -XPOST "http://localhost:8086/write?db=mydb" -d 'cpu,host=server02,region=uswest load=78 1434055562000000000'

- curl -XPOST "http://localhost:8086/write?db=mydb"  -d 'cpu,host=server03,region=useast load=15.4 1434055562000000000'

查询

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

分析

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