| Looking at the DNS/FQDN based GUID resolver. | |
| * Heavy on DNS resulution - latencies | |
| https://396d9ae0da7e5557b894b606231fa3ea.guid.podcastindex.org/ resolves to https://feeds.buzzsprout.com/1538779.rss | |
| If flipped around, the following pattern might be used; | |
| https://guid.podcastindex.org/396d9ae0da7e5557b894b606231fa3ea | |
| * could produce same result but would not require new DNS resolution | |
| * does not "pollute" the DNS space | |
| * allows for "prefetch" (pre-resolution in browsers) | |
| A counter part URN service would be set up to provide resolution the other way, which could overlap (Many-to-one) | |
| https://urn.podcastindex.org/urn/com/buzzsprout/feeds/1538779 or | |
| https://urn.podcastindex.org/urn:com:buzzsprout:feeds:1538779 | |
| Which could overlap with an equivalent, a copied feed on another hosting servce but that resolves to the same GUID .. | |

| Caching | |
| Redis - all-in-one, easy to update cache, persisted-to-disk in-memory. | |
| Varnish - cache to disk as disk storage is cheap and memory is expensive. |
