class VectorDBConnector extends AnnotatorModel[VectorDBConnector] with HasBatchedAnnotate[VectorDBConnector]
Connector for storing and retrieving embeddings from vector databases.
This annotator takes embeddings from previous annotators (like BertEmbeddings, SentenceEmbeddings, OpenAIEmbeddings, etc.) and stores them in a vector database for similarity search and retrieval. Currently supports Pinecone with more providers planned.
Supported Providers
- pinecone: Pinecone vector database (default)
Example

batchAnnotate(batchedAnnotations: Seq[Array[Annotation]]): Seq[Seq[Annotation]]
Required by HasBatchedAnnotate trait - but we override batchProcess instead since we need Row-level access for idColumn and metadataColumns.
Required by HasBatchedAnnotate trait - but we override batchProcess instead since we need Row-level access for idColumn and metadataColumns.
- batchedAnnotations
Annotations in batches that correspond to inputAnnotationCols generated by previous annotators if any
- returns
any number of annotations processed for every batch of input annotations. Not necessary one to one relationship IMPORTANT: !MUST! return sequences of equal lengths !! IMPORTANT: !MUST! return sentences that belong to the same original row !! (challenging)

batchProcess(rows: Iterator[_]): Iterator[Row]
Override batchProcess to get direct access to Row data.
Override batchProcess to get direct access to Row data.
This is necessary because we need access to additional columns (idColumn, metadataColumns) beyond just the annotations. The standard batchAnnotate only receives annotations.
