Writes could timeout and when adding new measurement names to the index if the sort took a long time. The names slice was never actually used (except a test) so keeping it in index wastes memory and sort it wastes CPU and increases lock contention. The sorting was happening while the shard held a write-lock. Fixes #3869 |

InfluxDB 
An Open-Source, Distributed, Time Series Database
InfluxDB v0.9.0 is now out. Going forward, the 0.9.x series of releases will not make breaking API changes or breaking changes to the underlying data storage. However, 0.9.0 clustering should be considered an alpha release.
InfluxDB is an open source distributed time series database with no external dependencies. It's useful for recording metrics, events, and performing analytics.
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.
- 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.
Getting Started
The following directions apply only to the 0.9.0 release or building from the source on master.
Building
You don't need to build the project to use it - you can use any of our pre-built packages to install InfluxDB. That's the recommended way to get it running. However, if you want to contribute to the core of InfluxDB, you'll need to build. For those adventurous enough, you can follow along on our docs.
Starting InfluxDB
service influxdb startif you have installed InfluxDB using an official Debian or RPM package.$GOPATH/bin/influxdif you have built InfluxDB from source.
Creating your first database
curl -G 'http://localhost:8086/query' --data-urlencode "q=CREATE DATABASE mydb"
Insert some data
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'
Query for the data
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"
Analyze the data
curl -G http://localhost:8086/query?pretty=true --data-urlencode "db=mydb" \
--data-urlencode "q=SELECT mean(load) FROM cpu WHERE region='uswest'"
Helpful Links
- Understand the design goals and motivations of the project.
- Follow the getting started guide to find out how to install InfluxDB, start writing more data, and issue more queries - in just a few minutes.
- See the HTTP API documentation to start writing a library for your favorite language.
