I have feature vectors with 2048 elements, also my feature may change overtime e.g. new features are added. I use Faiss as a search engine but I am not quite sure how to save these vectors. Right now I am syncing local folder with AWS s3. I do not think it is optimal because I have to sync files each time I search for similarity which takes a while.

Maybe I should use a vector database (like https://github.com/a-mma/AquilaDB or some other) or is there a more optimized method to sync my local and s3 storage?
