How to achieve deduplication and compression of data in Prometheus?
Implementing data deduplication and compression in Prometheus is usually achieved by configuring Prometheus’s storage policies. Here are some steps to implement data deduplication and compression:
- Configure storage policies: In the configuration file of Prometheus, you can establish storage policies to control the retention time and compression method of data. The retention time and size of data can be controlled by configuring storage.tsdb.retention.time and storage.tsdb.retention.size.
- Enable data compression: Prometheus supports compressing data to reduce storage space usage. Data compression can be enabled by configuring storage.tsdb.block-compression.
- Enable data deduplication: Prometheus by default will deduplicate data to reduce storage space usage. The way data deduplication is done can be controlled by configuring storage.tsdb.min-block-duration and storage.tsdb.max-block-duration.
- Restart Prometheus: After making changes to the configuration file, it is necessary to restart Prometheus for the changes to take effect.
By following the above steps, data deduplication and compression can be achieved in Prometheus, reducing the storage space occupied by data.
