Event Sourcing
Explore event sourcing as a method for data synchronization in distributed systems. Understand how append-only event logs and snapshots help maintain system state and handle failures. Learn about challenges like eventual consistency and how applications can address them to ensure reliable data updates.
Synchronizing data using event sourcing
Event sourcing is another approach for data synchronization. It writes any update operations to an append-only event log. The interested applications consume events from this log and store the associated data in their preferred datastore. The current state of the system can be derived simply by consuming all the events from the beginning of the log.
However, applications typically save periodical snapshots (also known as checkpoints) of the state to avoid having to re-consume the whole log in case of ...
