|Constructor and Description|
|Modifier and Type||Method and Description|
Returns a flux of ids for the documents that exist.
First checks if the given IDs exist and if so fetches their contents.
@Stability.Volatile public static Mono<Map<String,GetResult>> getIfExists(Collection collection, Collection<String> ids)
Please take into consideration when using this API that it only makes sense to use it if of the many ids provided only a small subset comes back. (So let's say you give it 1000 IDs but you only expect 50 to be there or so). Otherwise if all are most of them are there, just use a bulk get with the reactive API directly - you won't see much benefit in this case.
collection- the collection to perform the fetch on.
ids- the document IDs to fetch.
@Stability.Volatile public static Flux<String> exists(Collection collection, Collection<String> ids)
Note that you usually only want to use this API if you really need to bulk check exists on many documents
at once, for all other use cases we recommend trying the regular, supported APIs first
collection- the collection to perform the exists checks on.
ids- the document IDs to check.
