What is InfluxDB?
InfluxDB is a time-series database designed to handle high-volume and high-velocity data, making it an ideal solution for monitoring and logging applications. It is optimized for fast, high-availability storage and retrieval of large amounts of time-stamped data.
Main Features
InfluxDB offers several key features that make it a popular choice for monitoring and logging:
- High-performance data ingestion and querying
- Support for high-availability and clustering
- Flexible data retention and downsampling
- Native support for SQL and InfluxQL query languages

Retention and Encryption
InfluxDB provides several features for data retention and encryption.
Data Retention
InfluxDB allows you to configure data retention policies to control how long data is stored. You can set retention policies based on time, size, or a combination of both.
Configuring Retention Policies
Retention policies can be configured using the InfluxDB configuration file or through the InfluxDB API.
influxd config > influxdb.conf
Edit the configuration file to set the retention policy:
retention-policy =
