Percona Blog Poll Results: What Database Engine Are You Using to Store Time Series Data?

TIme Series DataIn this blog post, we talk about the results of Percona’s time series database poll “What Database Engine Are You Using to Store Time Series Data?”

Time series data is some of the most actionable data available when it comes to analyzing trends and making predictions. Simply put, time series data is data that is indexed not just by value, but by time as well – allowing you to view value changes over time as they occur. Obvious uses include the stock market, web traffic, user behavior, etc.

With the increasing number of smart devices in the Internet of Things (IoT), being able to track data over time is more and more important. With time series data, you can measure and make predictions on things like energy consumption, pH values, water consumption, data from environment-aware machines like smart cars, etc. The sensors used in IoT devices and systems generate huge amounts of time-series data.

A couple of months back, we ran a poll on what time series databases were being used by the community. We wanted to quickly report on the results from that poll.

First the results:

Note: There is a poll embedded within this post, please visit the site to participate in this post’s poll.

Here are some thoughts:

  • The fact that this blog started as a place exclusively for MySQL information probably explains why we skewed high with MySQL respondents – still that doesn’t mean it doesn’t reflect reality.
  • Elastic seems the most common after that, possibly to tie in with MySQL use.
  • InfluxDB as next popular. This suggests that Paul Dix’s chosen business model is “AOK” so to speak. It is unclear if people use the open source version, or outgrow it and switch to the commercial stuff.
  • We lumped together “general purpose NoSQL engine”, but in some cases examples like Cassandra are targeted at time series. Notice that KairosDB, which is built on top of Cassandra itself, is not as popular in our survey.
  • Prometheus is the canonical “not a time series database”, but still used as one. I have a feeling alongside Graphite, this is monitoring related.
  • ClickHouse time series is a new time series database and it is surprising that it gets such high rankings. It was also relatively unknown outside of its home country Russia, but now we are seeing uses at places like CloudFlare and more.

Thanks for participating in the poll. We’re still running a poll on operating systems, so don’t forget to register your responses. We’ll report on that poll soon, with a new one on the way shortly.


Percona Poll: What Database Technologies Are You Using?

Database Technologies

Database TechnologiesTake Percona’s poll on what database technologies you use in your environment.

Different databases get designed for different scenarios. Using one database technology for every situation doesn’t make sense, and can lead to non-optimal solutions for common issues. Big data and IoT applications, high availability, secure backups, security, cloud vs. on-premises deployment: each have a set of requirements that might need a special technology. Relational, document-based, key-value, graphical, column family – there are many options for many problems. More and more, database environments combine more than one solution to address the various needs of an enterprise or application (known as polyglot persistence).

Please take a few seconds and answer the following poll on database technologies. Which are you using? Help the community learn what technologies critical database environments employ. Please select from one to six technologies as they apply to your environment.

If you’re using other solutions or have specific issues, feel free to comment below. We’ll post a follow-up blog with the results!
