View Source Carve.Batch (Carve v0.6.0)
Batched cache warm-up for views that define cache_many.
warm/3 resolves the cached value for a set of entities of one view in a
single __cache_many__/1 call, instead of one __cache__/1 call per
entity. Views without cache_many fall back to the per-entity path,
preserving the existing cache behavior exactly.
Summary
Functions
Whether the view module declares cache_many.
Returns a map of entity id => cached value for every entity in items,
warming the request cache along the way.
Functions
Whether the view module declares cache_many.
Returns a map of entity id => cached value for every entity in items,
warming the request cache along the way.
For a view with cache_many, entities already present in the request
cache are excluded from the batch call; ids missing from the returned
map are cached as nil. Batching also works when caching is disabled
(cache_key is nil): the batch still runs once and the results are
returned directly.
