AddedRowsScanTask

All Superinterfaces:

ChangelogScanTask, ContentScanTask<DataFile>, PartitionScanTask, ScanTask, java.io.Serializable
```
public interface AddedRowsScanTask
extends ChangelogScanTask, ContentScanTask<DataFile>
```
A scan task for inserts generated by adding a data file to the table.
Note that added data files may have matching delete files. This may happen if a matching position delete file is committed in the same snapshot or if changes for multiple snapshots are squashed together.
Suppose snapshot S1 adds data files F1, F2, F3 and a position delete file, D1, that marks particular records in F1 as deleted. A scan for changes generated by S1 should include the following tasks:
- AddedRowsScanTask(file=F1, deletes=[D1], snapshot=S1)
- AddedRowsScanTask(file=F2, deletes=[], snapshot=S1)
- AddedRowsScanTask(file=F3, deletes=[], snapshot=S1)
Readers consuming these tasks should produce added records with metadata like change ordinal and commit snapshot ID.
