Powerful Time-Series Database For Monitoring Solution. “ Askjitendrakumar.com
A time-series database is designed for time-series or timestamp data. Time-series data refers to events or measurements that are recorded, monitored, or gathered over time.
It could include data collected from the motion-tracking sensors. JVM measurements from Java applications, market trade information, API responses, network data, process uptime, etc.
Time-series databases can be completely personalized with timestamped information that is efficiently indexed and written so that it is possible to insert time-series data. It is possible to query these time-series data faster than performing it in a relational or a NoSQL database.
In recent times it has received lots of attention. It’s not surprising. It is an excellent tool for both businesses as well as IT operation monitoring. It’s a good thing that there are a lot of choices and the majority are open source:
InfluxDB
InfluxDB is among the most widely used time-series databases in DevOps that was written using Go. InfluxDB was created from scratch to be highly scalable storage and data ingestion system.
It’s very effective at taking data, storing, visualizing, querying, and responding to time-series data streams, including events, metrics, and events in real-time.
It supports down sampling and retention policies for data to keep high-value and high precision data in memory and more minor value data off to disk.
It is built upon cloud-native technology to provide the ability to scale across different deployment models such as cloud on-premises and hybrid environments.
InfluxDB is an open-source solution and enterprise-ready. It utilizes InfluxQL that is like a structure query language for interfacing with data. The most recent version includes agents, dashboards and tasks, and queries in an instrument kit.
It’s an all-in-one solution to create dashboards, visualize, and alert.
Features:
- Performance for time-series information that has high through-the-day ingest and real-time queries
- InfluxQL is a data-based language that can interact which an SQL is similar to a query language
- The TICK core component is the (Telegraf, InfluxDB, Chronograf along with Kapacitor) stack.
- Support for plugins for protocols like collected, Graphite, and OpenTSDB for data ingestion
- Can process thousands of data points in 1 second
- Retention policies that automatically remove the data that is no longer needed
Since it’s an open-source project, it’s possible to download it and install it on your web server. But, they also offer InfluxDB Cloud on AWS, Azure as well as GCP.
Prometheus
Prometheus is an open-source monitor tool designed to gain insights from the metrics data and issue the necessary alerts. It comes with a local disk time-series database that stores data in a customized data format stored on a disk.
The Prometheus data model has multi-dimensional, based on time series. It keeps all the data in a stream of values that have been timestamped. It’s highly efficient when working with entirely numeric time series. The ability to collect micro services data and query it is among the advantages of Prometheus.
It is tightly integrated closely with Grafana to provide visualization.
Features:
- It has a multi-dimensional model that utilizes key-value and metrics name pairs (labels)
- PromQL to query time series data to create alerts, tables, as well as Adhoc graphs
- Uses HTTP pull mode to collect time-series data
- Uses an intermediary gateway to push time series
Prometheus offers numerous exporters to transfer files to Windows, Linux, Java, Database, APIs, Websites, Server Hardware, PHP, Messaging, and more.

TimescaleDB
TimescaleDB is an open-source relational database that allows SQL flexibility for time-series information. This database is built upon PostgreSQL.
It has two options. The initial choice is the community version available for free, and you can install it on your server. Its second alternative will be TimescaleDB Cloud, where you receive a fully managed and hosted infrastructure on the cloud to meet your deployment needs.
It is a great tool to assist with DevOps monitoring and understanding metrics for applications monitoring data via IoT devices, analyzing financial data and more. It can be used to measure the logs of your devices, Kubernetes activities, Prometheus metrics, and even custom metrics.
For owners of products, You can use it to study the performance of a product throughout time-this assists in making decisions that are strategic to grow the product.
Features:
- Perform queries 10 to 100 times quicker than PostgreSQL, MongoDB
- It can scale up to petabytes horizontally and write millions of data points every second
- Very like PostgreSQL, which makes it simple for administrators and developers to manage
- Combines time-series and relational database functions to build robust applications.
- In-built algorithms and performance feature to cut down on cost.
Graphite
Graphite can be described as a complete tool for storing and effectively displaying real-time time-series data. Graphite can do two things to store time-series information and render graphs upon demand.
However, it does not collect data on your behalf; for that, you’ll need tools like collectd, Ganglia, Sensu, Telegraf, etc.
It is composed of three parts, namely Carbon, Whisper, and graphite-web. Carbon takes in the time-series data, combines it, and saves it onto the disk. Whisper is a time-series database that holds the data. It is the front-end used for making dashboards and for visualizing the data.
Features:
- The format of metrics in which the data is presented is simple.
- Complete API for rendering data, making dashboards, charts, and graphs, and dashboards
- Offers a wide range of statistics library and transformative rendering capabilities
- Chains multiple render functions to build a query for the target.
QuestDB
QuestDB is a column-oriented relational database that can perform real-time analytics of historical data. It uses SQL as well as some extensions to build a relational model for data from time series.
QuestDB was developed entirely from scratch and did not have dependencies that could hinder its performance.
QuestDB has support for relational and time-series joins. IT helps in integrating the data. The most convenient method to start using QuestDB is to set it up in the Docker container.
Features:
- Interactive console for importing data by dragging and dropping and then querying it
- Cloud-native support is available by cloud-native (AWS, Azure, GCP) or on-premises. embedded
- Integrates enterprise systems by incorporating features such as active directory high availability, security for the enterprise, clustering
- Offers real-time insight by using predictive and operational analytics
