Hi Alyson,

Thanks for the link! It looks like the video covers using timestamps to implement replicated mvcc correctly from primary to other replicas.

The interesting next step is how you go from there to multi-document across different primaries. Or is this limited to documents in a single shard?

In 4.0, transactions will just be across replica-sets. The following release will have transactions across the entire sharded cluster (across multiple primaries).
