Operation History vs. ActionTrail
DataWorks also integrates with ActionTrail for account-level audit logging. The two tools serve different audiences:
| Operation History | ActionTrail | |
|---|---|---|
| Purpose | Development-side audit — trace who changed a node, committed code, or downloaded data | Compliance-level audit — track all Alibaba Cloud account activity |
| Target audience | Data engineers, workspace admins | Security and compliance teams |
| Retention | Not specified in product documentation | Last 90 days |
| Scope | Current workspace | Entire Alibaba Cloud account |
If other engines are integrated with ActionTrail, all operation records of those engines within your Alibaba Cloud account are also queryable.
