[shubhammahure]

Description

Using LLM, generate meta data for empty fields within an engine.
Should not overwrite fields that contain data
Generate meta data for empty fields

User should have some way to select what info is being sent to LLM for generation. Ex: give option for engine schema, sample rows, typing in additional details etc. User should always know what is being sent so data is not being leaked unknowingly.

How to Test

You can test in run pixel(Notebook cell) call
just replace your engineid and model id and provide options listed below(engine wise)
GenerateEngineMetadata(engine=["engineid"], model=["modelid"], metaKeys=[["description","tag"]], storagePath=["storagepath"], filePath=['filepath'], options=[{"includeSchema":true,"includeVectorFileNames":false,"includeVectorChunks":true,"includeStorageFileNames":true,"includeModelSmssInfo":true, "includeFunctionSmssInfo":2, "includeStorageFileContent":true }]);

Example for StorageEngine
GenerateEngineMetadata(engine=["ed23348f-842c-417d-...."], model=["4801422a-5c62-421e-a00c-05c6...."], metaKeys=[["description","tag"]], storagePath=["/abcd3"], filePath=['/shubh'], options=[{"includeStorageFileNames":true,"includeStorageFileContent":true }]);
