So you have a batching mechanism for creating TrailDB files, right? Then you're able to query historical metrics by processing these TrailDB files.

- erichocean 10y agoCorrect. We mostly use hdr_histogram right now for the post-processing, since stable latency is what we care about. We also do some hdr_histogram processing for our dashboard in parallel to storing traces in TrailDB, and then we retain the individual traces to do longer term processing or when we're tracking down issues in production.
