What is time series data?
Why shouldn't I just use a relational database?
What is time series data?
Time series data is a series of data points each associated with a specific time. Examples include:
- Server performance metrics
- Financial averages over time
- Sensor data, such as temperature, barometric pressure, wind speeds, etc.
Why shouldn't I just use a relational database?
Relational databases can be used to store and analyze time series data, but depending on the precision of your data, a query can involve potentially millions of rows. InfluxDB is purpose-built to store and query data by time, providing out-of-the-box functionality that optionally downsamples data after a specific age and a query engine optimized for time-based data.
