Greetings!
The issue you're encountering is related to the concurrent execution of copy activities in your Azure Data Factory pipeline. When you attempt to copy a large file multiple times in a short period, the first few copies succeed, but subsequent attempts fail because the file is still in use.
To resolve this issue, you can follow these steps:
- Modify the Pipeline Configuration: Adjust the concurrency settings of your pipeline to ensure that the copy activities do not execute simultaneously on the same file. This can be done by limiting the number of concurrent runs or adding a delay between each copy attempt.
- Use Dependency Conditions: Implement dependency conditions in your pipeline to ensure that the next copy activity starts only after the previous one has completed successfully.
- Retry Mechanism: Configure a retry mechanism for the copy activities to handle transient failures due to file access conflicts.
For detailed guidance on configuring these settings, refer to the Azure Data Factory documentation on pipeline concurrency and activity dependencies.
