CacheFill

Enum CacheFill 

Source
pub enum CacheFill {
    CacheEager,
    CacheLazy,
}
Expand description

A blob’s Remote story: how a device gets the bytes once the blob is Remote. A cache-mechanism setting — it describes a blob only while Remote — that applies to ANY blob regardless of Provenance. Orthogonal to provenance; a blob declares both.

Both classes are declared per blob and are global (every device reads the same class from the blob’s BlobRef); the difference is what a device does with the blob on pull. The distinction has to be a declared property and not a per-device choice: device B, deciding during its own pull whether to fetch a blob, can only read the blob’s declared class — it cannot see what device A chose locally.

Variants§

§

CacheEager

Fetched into the cache on pull, right away, on every device — part of “having the store” (e.g. cover art, so the grid renders from local bytes without a fetch). The cache copy is evictable + re-fetchable, not pinned.

§

CacheLazy

Not fetched on pull: a pulling device skips it and fetches it into the cache on first read — e.g. audio, which is big and streams on demand.
