libSQL embedded replica API is much more ergonomic now with read-your-write support. Embedded replicas in libSQL provide local reads and delegate writes to a remote server. Until recently, you had to explicitly call a sync() method to get changes. But now that @lucio_d_franco added support for read-your-writes (implicit sync on write), you can get fast local reads and transparent remote writes automatically. If you run this program multiple times, you will retain a local copy of the database, but sync up with other concurrent writers automatically while still serving reads locally. You can still call the sync() method manually, but that becomes a data freshness thing, not a correctness thing. We're planning on supporting local writes too at some point, but as @glcst pointed out recently, most people seem to just need read-your-writes even when talking about local writes. Curious to see how far we ca go with just this approach!
