An append-log of Events for your application.
- Event History is durably persisted by the Temporal service, enabling seamless recovery of your application state from crashes or failures.
- It also serves as an audit log for debugging.
Event History limits The Temporal Cluster stores the complete Event History for the entire lifecycle of a Workflow Execution. There is a hard limit of 50,000 Events in a Workflow Execution Event History, as well as a hard limit of 50 MB in terms of size. The Temporal Cluster logs a warning at every 10,000 Events. When the Event History reaches 50,000 Events or the size limit of 50 MB, the Workflow Execution is forcefully terminated.
