Data → Get Data by Offset
AI-generatedOverview
This node operation retrieves data rows from a specified task in Octoparse starting from a given offset position. It is useful for paginating through large datasets extracted by Octoparse tasks, allowing users to fetch data in manageable chunks. For example, a user can fetch 100 rows starting from row 0, then fetch the next 100 rows starting from row 100, and so on.
Use Case Examples
- Fetch 100 rows of data starting from offset 0 for a specific task in a task group.
- Retrieve data in batches by specifying different offset values to paginate through the dataset.
Properties
| Name | Meaning |
|---|---|
| Task Group | Select the task group to find the task in. |
| Task | Select the specific task from which to retrieve data. |
| Offset | Starting position of data retrieval, indicating from which row to begin fetching data. |
| Size | Number of rows to retrieve, with a range from 1 to 1000. |
Output
JSON
data- The retrieved data rows from the specified task starting at the given offset.
Dependencies
- Octoparse API key credential for authentication.
Troubleshooting
- Common issues include invalid task group or task IDs, which result in empty or error responses. Verify that the selected task group and task exist and are accessible.
- Offset and size parameters must be within valid ranges; offset must be zero or positive, and size must be between 1 and 1000.
- API rate limits or authentication errors may occur if the API key is invalid or expired. Ensure the API key credential is correctly configured and valid.
