DVInMemoryVectorAdapter class

The reference adapter: exact cosine search in memory.

For development and tests. Deliberately not a vector store to deploy — the specification leaves those to pgvector and the search services, since a hand-rolled index would be the slowest and least-tested part of the framework.

Methods

dropIndex(String index) → Future<void>

override

nearest(String index, List<double> vector, {required int k, DVVectorFilter? filter}) → Future<List<DVVectorMatch>>

override

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

readMeta(String key) → Future<String?>

Small durable values the index keeps about itself: which generation is active, which records a backfill has done, which job carried which record.

override

removeRecord(String index, String recordId) → Future<void>

override

toString() → String

A string representation of this object.

inherited

upsert(String index, List<DVVectorEntry> entries) → Future<void>

Stores a record's chunks, replacing any it had.

override

writeMeta(String key, String? value) → Future<void>

override

Operators

operator ==(Object other) → bool

The equality operator.
