When configuring using 'FileSource', how do I add a file with new data to reflect it?

[sungreong]

I want to configure the feature store with an existing file and reflect it in the feature store when a new file is added.

I'm looking at several examples, but I can't find any of these examples.

I have a few questions regarding this.

1. When a new file is added, how do I add a new file while retaining the data of the existing file?

2. If question 1 is impossible, how can we add new data to the online store for new files?

Thank you for making a good library, and I look forward to a good answer.

Hey @sungreong, this is a good question - the real answer is that this use case isn't really supported, since the file offline store is meant just for dev environments/getting started with Feast. For production, we generally recommend using one of the other supported offline stores, which support your use case.
