LiteFS multiple databases

@benbjohnson

We can add the ability to track consistency across multiple databases. We’d just need to update the cookie set by the proxy to list multiple databases’ TXID.

@benbjohnson Are you planning to implement it? Could you explain the trade-offs involved? How significant is the lag behind the primary?

[benbjohnson]

Yes, I can implement it since there’s interest. All the replication goes through a single stream right now so two databases in a cluster should have basically the same lag as one another. The main tradeoff was added complexity.
