vdf-io 0.0.8

This library uses a universal format for vector datasets to easily export and import data from all vector databases.

This library uses a universal format for vector datasets to easily export and import data from all vector databases.

See the Contributing section to add support for your favorite vector database.

Universal Vector Dataset Format (VDF) specification

1. VDF_META.json: It is a json file with the following schema:

interface Index {
  namespace: string;
  total_vector_count: number;
  exported_vector_count: number;
  dimensions: number;
  model_name: string;
  vector_columns: string[];
  data_path: string;
  metric: 'Euclid' | 'Cosine' | 'Dot';
}

interface VDFMeta {
  version: string;
  file_structure: string[];
  author: string;
  exported_from: 'pinecone' | 'qdrant'; // others when they are added
  indexes: {
    [key: string]: Index[];
  };
  exported_at: string;
}

2. Parquet files/folders for metadata and vectors.

Contributing

Adding a new vector database

If you wish to add an import/export implementation for a new vector database, you must also implement the other side of the import/export for the same database. Please fork the repo and send a PR for both the import and export scripts.

Changing the VDF specification

If you wish to change the VDF specification, please open an issue to discuss the change before sending a PR.

Efficiency improvements

If you wish to improve the efficiency of the import/export scripts, please fork the repo and send a PR.

Questions

If you have any questions, please open an issue on the repo or message Dhruv Anand on LinkedIn
