Carl Sverre @carlsverre of SQLSync is speaking at Sync Conf 2025 on partial replication.
He takes a slightly contrarian view: no CRDTs, but instead block-level replication. Hear all about it on Nov 12.

Irakli & Chris (independent researchers) will show us reactive UIs via declarative Datalog rules and sync through commodity blob stores like S3. Irakli and Chris' research perspective should make a nice constrast to the commercial focus for the rest of the conf.

We don't have a particular hotel that we're partnering with for the conf, however last time I (Johanna) was in SF I stayed at maps.app.goo.gl/TrpF5bSN8Zgs… and I really enjoyed the atmosphere. It's walking distance to the venue too.
