Function: distinctJoinKeys()
distinctJoinKeys(
rows,reference,threshold,options?):Set<unknown>
Defined in: core/src/plugins/query/join.ts:250
The distinct join keys of the outer rows, or null when there are too many to be worth sending.
null means "do not prefilter", not "no keys" — an empty SET is a real answer meaning the inner side cannot match anything.
Parameters
rows
readonly UnknownRecord[]
reference
threshold
number = DEFAULT_SEMI_JOIN_KEY_THRESHOLD
options?
storageShape?
boolean
Returns
Set<unknown>
