- ODATA entries are not served to clients if they are older than the max metadata age.
RATIONALE / BACKGROUND
Currently, NuGet does not respect the proxy repository configuration 'Max metadata age': ODATA never expires. This isn't normally a problem because NuGet metadata is regularly overwritten by fresh ODATA as feeds are proxied.
However, 'orphan metadata' can occur - if Nexus caches ODATA for a remote artifact, never downloads the content, then that remote artifact disappears, Nexus will forever serve ODATA but 404 on the component itself.
Please ensure that any date fields you create or use have the exact meaning you require, rather than overloading an existing one (c.f. the somewhat ambiguous Asset.lastUpdated).
