@concile/transactor

The single-writer, optimistic-concurrency transaction engine at the heart of Concile's write path.

This package runs each mutation as a serializable transaction over the append-only document log: it executes the function against a snapshot, validates its recorded read set against commits that landed concurrently, and either applies the staged writes atomically or replays the function on conflict. Every commit emits a delta that the sync tier fans out to invalidate subscriptions, which is what makes writes reactive. Group commit batches concurrent transactions through the single writer for throughput, and a sharded variant partitions the write path across multiple writers while preserving cross-shard read consistency.

This is an internal package of the Concile engine. Most applications should install concile instead.
