Really great write up on labels and cardinality. These are just a few points I noticed but they are only suggestions :) |

| [Structured metadata](https://grafana.com/docs/loki/<LOKI_VERSION>/get-started/labels/structured-metadata/) is a feature in Loki and Cloud Logs that allows customers to store metadata that is too high cardinality for log lines, without needing to embed that information in log lines themselves. | ||
| It is a great home for metadata which is not easily embeddable in a log line, but is too high cardinality to be used effectively as a label. |

Should it mention bloom filters here as well? The whole point of putting high cardinality fields into structured metadata is that you can filter them relatively efficiently using blooms.

Good point. What do you suggest for wording?
