Incremental Reprocessing One of the biggest pain points with PowerSync was that even a small change to your sync config required re-replicating everything from scratch, and clients had to re-sync all their data.

With storage version 4, most Sync Streams deploys reprocess only the streams you’ve added or changed. Clients only re-download data for those affected streams. Some changes still require a full reprocess, but routine config updates become much lighter.

Available for MongoDB sources using Sync Streams. Support for Postgres and other source databases is planned.
