Yet RRD databases are awfully big but often compress to single digit percentages. We use them to store one time graph data, so they do not ever get updated after the report job finishes. I'm looking for an alternative and it better not be a huge json array of arrays plus a header dictionary. It also should be an on disk something, not Influx or Prometheus.
- simonmales 5y agoI only know RRD from Munin graphs, and now have a toy idea to used it directly to render a SVG. If disk space is an issue, do you or have you considered decompressing on the fly ?
- chrismorgan 5y agoOr use a file system that supports transparent compression (e.g. btrfs).
- SuperQue 5y agoYou can use the Prometheus TSDB package, it's easy to import and use. Plus it's designed around mmap, so the kernel deals with the caching. You don't have to use a whole Prometheus server to make something like this work.
