:rocket: This description was created by Ellipsis for commit 5e2a59276706d3d3f00abdabb684d17ddd615d1e

Summary:

Enhances Weaviate export and import functionalities with support for multiple connection types, batch processing, and integration of OpenAI API key, with import functionality needing completion.

Key points:

• Added support for local and cloud connections in ExportWeaviate and ImportWeaviate.
• Integrated OpenAI API key handling in Weaviate connections.
• Implemented batch processing for exporting data to Parquet files in ExportWeaviate.
• Prepared structure for importing data from Parquet files in ImportWeaviate, but actual data upsert code is commented out.
• Environment variables are used for connection details, and progress is visualized using tqdm.

@emekaokoli19 did you test the newest version of the code with a weaviate instance?

@dhruv-anand-aintech I am sorry for the late reply, I was out for a few days but I am back now. Yes the code was tested with a weaviate instance and it works

@emekaokoli19 you need to make sure that it works for any import command. eg:

import_vdf \
    --max_num_rows 1000 \
    --hf_dataset aintech/vdf_prefix-cache \
    weaviate

Here it asks me for index name, which it should be using the name from the VDF_META.json file (see other DBs' implementation).

It also fails because openai_api_key is not set. This is not a required API key for importing datasets. You need to make sure the code works without it being set (using .get("openai_api_key", "") syntax.

Let's have a pair programming session to finish off this task. Please message me on discord to set a time
