pg-atomic-ledger
pg-atomic-ledger is an open-source PostgreSQL extension and schema framework providing cryptographically sealed double-entry transaction tables, row-level pessimistic balance locking, and Kafka audit logs stream synchronization.
Architecture & Core Features
Pessimistic Balance Locking - Row-ordered locks eliminating deadlock collisions during parallel collections
Immutable Double-Entry Ledger - Strictly balanced credit/debit validation enforced at the engine triggers level
Kafka Audit Stream Dispatcher - Automated hooks push mutations immediately into streaming log channels
What stood in the way?
Maintaining strict concurrency balance locks without causing circular database deadlock wait states.
How Emicraft engineered it
Designed lock-ordered transactional workflows in PL/pgSQL sorting account keys before acquiring row locks.
