# Downsample data stored in InfluxDB

Learn about different methods for querying and downsampling time series data stored in InfluxDB.

### [Downsample data with client libraries](/influxdb3/cloud-serverless/process-data/downsample/client-libraries/)

Use InfluxDB client libraries to query and downsample time series data stored in InfluxDB and write the downsampled data back to InfluxDB.

### [Use Quix Streams to downsample data](/influxdb3/cloud-serverless/process-data/downsample/quix/)

Use [Quix Streams](https://github.com/quixio/quix-streams) to query time series data stored in InfluxDB and written to Kafka at regular intervals, continuously downsample it, and then write the downsampled data back to InfluxDB.
