Dimensions summary
quasarDB Community Edition is free software. You pay nothing for the license itself. Pricing here reflects only the AWS EC2 instance you choose to run it on, billed hourly. Each dimension maps to a specific instance type from the t3, c5, c6a, c6i, m5, m6a, m6i, r6a, and r6i families. These families differ in CPU, memory, and size, from small t3.nano options to large metal and 48xlarge instances. You select the instance that fits your workload; hourly cost scales with the instance size and family you pick.
Top-of-mind questions for buyers
quasarDB Community Edition is free software, so the license adds no charge. Each hourly rate reflects only the AWS EC2 instance you run it on. You pay for one running instance per hour, based on the instance type you select from the listed families.
The software license is free, so no license charge applies whether the instance runs or not. Hourly charges here reflect the running EC2 instance. A stopped instance stops accruing instance-hour charges, though attached AWS storage may still incur separate storage fees.
The families differ in CPU-to-memory balance and size. The c-families favor compute-heavy work, m-families balance compute and memory, r-families favor memory-heavy work, and t3 suits small or variable workloads. Sizes range from nano up to metal and 48xlarge, so cost scales with the size you choose.

Amazon Machine Image (AMI)
An AMI is a virtual image that provides the information required to launch an instance. Amazon EC2 (Elastic Compute Cloud) instances are virtual servers on which you can run your applications and workloads, offering varying combinations of CPU, memory, storage, and networking resources. You can launch as many instances from as many different AMIs as you need.

Usage instructions
-
QuasarDB runs as a systemd service, you can inspect its status as follows:
systemctl status qdbd.service
-
An exported of QuasarDB metrics to Amazon Cloudwatch has been preinstalled and configured as a systemd service. You can inspect its status as follows:
systemctl status qdb-cloudwatch.timer systemctl status qdb-cloudwatch.service
In order for the exporter to work, it requires the relevant IAM permissions assigned to this EC2's instance role.
-
To connect to your QuasarDB instance, you can use qdbsh:
qdbsh qdb://127.0.0.1:2836
-
For security purposes, QuasarDB only listens to localhost by default.
-
You can configure and customize your QuasarDB installation by editing the configuration file at /etc/qdb/qdbd.conf.

What do you like best about the product?
QuasarDB is a clear innovation. QuasarDB enables you to store massive amount of data without sacrificing on query speed.
The level of performances that one can leverage is clearly at least one order of magnitude over a lot of competitors. From
the large selection of platforms and languages to high-performance compression features, it really simplifies
the management of large scale databases.
A must-have if performances on your whole stack is a required.

High performance timeseries database that is great with numbers
Reviewed on Mar 16, 2019
Review provided by G2
What do you like best about the product?
The performance of numerical calculations is superb -- when offloading calculations / aggregates to the database, it is able to achieve stellar performance.
What do you dislike about the product?
It takes some time to learn how to use it. The UI is very unforgiving sometimes, although it does seem to get better with every release.
What problems is the product solving and how is that benefiting you?
We moved from InfluxDB, and especially exploring our dataset has been much easier: the speed of the engine make it easy to interactively test and iterate on your queries.
Recommendations to others considering the product:
Make sure your data is mostly numerical, this is where you will be seeing the most benefits of using QuasarDB.
