What You Need To Know About InfluxDB

InfluxDB is a Time series Database

A Time series Database (TSDB) is a kind of database that stores values that evolve during time.Typically, a temperature will evolved each minute. A Time series Database will store a key "temperature", and then associate an array of timestamp and value that will be filled each minute.This kind of database is designed to store the metrics and The Influx database is probably most world-famous database of this kind.

When to use InfluxDB?

InfluxDB is the best if you want to store, query & analyzes metrics data, like IoT sensorss, monitoring records, or applications metrics.

When not to use InfluxDB?

If you want to store data which are not metrics, like (user information, message, and PDF documents) then InfluxDB is not a good choice to do.

What makes InfluxDB so great?
 

InfluxDB is a great product for the mentioned reasons :

• It handles the telemetry data like monitoring, applications metrics, or IoT sensors
• The data are automatically compressed into the managed disk occupation efficiently
• Retention policies can be applied to delete automatically old data after a given amount of time
• The Flux language is super powerful and permits to analyze of depth stored data
• InfluxDB WEB UI gives the ability to create beautiful dashboards in minutes

Differences between InfluxDB and relational/SQL databases:

A Time series Database is totally different from a relational database (like MySQL or PostgreSQL) as it doesn't create relationships between data. Time series Databases will not be able to do this kind of job.

Differences between InfluxDB and NoSQL databases :

A NoSQL DB (ex: MongoDB or OpenSearch) stores the data like documents. It is an association of multiple data, like a user name, birthday, and its email.

NoSQL databases are competitors of SQL relational databases and, as such, are not designed to store metrics data like InfluxDB does.
