kdbai Import data to KDB.AIThis Python script is used to re-embed a vector dataset. It takes a directory of vector dataset in the VDF format and re-embeds it using a new model. The script also allows you to specify the name of the column containing text to be embedded.

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.
Steps to add a new vector database (ABC):
- Add your database name in src/vdf_io/names.py in the DBNames enum class.
- Create new files
src/vdf_io/export_vdf/export_abc.pyandsrc/vdf_io/import_vdf/import_abc.pyfor the new DB.
Export:
- In your export file, define a class ExportABC which inherits from ExportVDF.
- Specify a DB_NAME_SLUG for the class
- The class should implement:
- make_parser() function to add database specific arguments to the export_vdf CLI
- export_vdb() function to prompt user for info not provided in the CLI. It should then call the get_data() function.
- get_data() function to download points (in a batched manner) with all the metadata from the specified index of the vector database. This data should be stored in a series of parquet files/folders. The metadata should be stored in a json file with the schema above.
- Use the script to export data from an example index of the vector database and verify that the data is exported correctly.
Import:
- In your import file, define a class ImportABC which inherits from ImportVDF.
- Specify a DB_NAME_SLUG for the class
- The class should implement:
- make_parser() function to add database specific arguments to the import_vdf CLI, such as the url of the database, any authentication tokens, etc.
- import_vdb() function to prompt user for info not provided in the CLI. It should then call the upsert_data() function.
- upsert_data() function to upload points from a vdf dataset (in a batched manner) with all the metadata to the specified index of the vector database. All metadata about the dataset should be read from the VDF_META.json file in the vdf folder.
- Use the script to import data from the example vdf dataset exported in the previous step and verify that the data is imported correctly.
If you wish to change the VDF specification, please open an issue to discuss the change before sending a PR.
If you wish to improve the efficiency of the import/export scripts, please fork the repo and send a PR.
Running the scripts in the repo will send anonymous usage data to AI Northstar Tech to help improve the library.
You can opt out this by setting the environment variable DISABLE_TELEMETRY_VECTORIO to 1.
If you have any questions, please open an issue on the repo or message Dhruv Anand on LinkedIn
