Description

like this issue https://github.com/mosaicml/streaming/issues/832
Lance can perform random reads very well, and the primary key can bring good shuffle ability. However, streaming can provide a better shuffle algorithm for training.
So I bring up the possibility of this combination again here and want to discuss the ideas of the community here.

Research direction

Start by reading the linked MosaicML Streaming issue and this issue's discussion to understand the proposed Lance and streaming combination. The work is not yet scoped to files or tests; done would require an agreed integration design for random reads, primary-key-based access, and training-data shuffling.
