WalkKeys serially walked each TSM file and invoked fn for each key. Caller needed to handle duplicate calls to fn with the same key because the same key could exist in multiple TSM files. The serial execution was also slower. Since the series keys are already sorted, we can iterate over all files in parallel and skip duplicates using a sorted merge. This fixes the duplicate invocation issue as well as speeds up walking all keys. This can significant improve startup performance when many TSM files exists that may not have been fully compacted. This also has benefits for deletes (measurements/series) since duplicates are removed saving extra allocations and work. This may also allow for the optimize compaction to be removed provided startup times are fast enough. |

InfluxDB 
An Open-Source Time Series Database
InfluxDB is an open source 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.
- 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.
Installation
We recommend installing InfluxDB using one of the pre-built packages. Then start InfluxDB using:
service influxdb startif you have installed InfluxDB using an official Debian or RPM package.systemctl start influxdbif you have installed InfluxDB using an official Debian or RPM package, and are running a distro withsystemd. For example, Ubuntu 15 or later.$GOPATH/bin/influxdif you have built InfluxDB from source.
Getting Started
Create your first database
curl -XPOST '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'"
