GetAsync(IEnumerable

This method retrieves a batch of records from the vector store. It does not guarantee that the collection exists and returns null if the record is not found.

  The unique IDs associated with the records to retrieve.

  Optional options for retrieving the records.

• cancellationToken

  The cancellation token.

Return Value

IAsyncEnumerable<Dictionary<string, object?> object representing the result set of found records.

Microsoft.Extensions.VectorData.VectorStoreCollection

Exceptions

VectorStoreException: The command fails to execute for any reason other than the absence of a record.

Unlike OracleCollection, OracleDynamicColloection uses Object as TKey, and Dictionary<string, object?> as TRecord. Please make sure to use the correct parameter types: IEnumerable<Object> for keys.
