Hi @Devin12355, do you see your listener being called with TransferState.COMPLETED? Any additional details you could provide would help narrow this issue down.

hi @mattcreaser
aws-android-sdk-s3 version:2.81.0

During the transfer process, I saw that files larger than 5M were sliced into multiple segments for uploading, and the database is as follows:
https://raw.githubusercontent.com/Devin12355/pic-cache/main/aws4.jpeg

​ after finish upload file with TransferUtility.upload I have receive the TransferState.COMPLETED message from this callback TransferListener.onStateChanged,I saw that "_id" is "1" has already delete but main_uoload_id is "1" not delete ,the database as follows:
https://raw.githubusercontent.com/Devin12355/pic-cache/main/aws3.jpeg

database may keep growing larger if the database is not cleaned, I'm not sure if there is a corresponding interface to clean it.

//java/com/amazonaws/mobileconnectors/s3/transferutility/TransferDBBase.java
 public int delete(Uri uri, String selection, String[] selectionArgs) {
      final int uriType = uriMatcher.match(uri);
      int rowsDeleted = 0;
      ensureDatabaseOpen();
      switch (uriType) {
          case TRANSFERS:
              rowsDeleted = database.delete(TransferTable.TABLE_TRANSFER, selection,selectionArgs);
              break;
          case TRANSFER_ID:
              final String id = uri.getLastPathSegment();
              if (TextUtils.isEmpty(selection)) {
                   rowsDeleted = database.delete(TransferTable.TABLE_TRANSFER, TransferTable.COLUMN_ID + "=" + id, null);
              } else {
                  rowsDeleted = database.delete(TransferTable.TABLE_TRANSFER, TransferTable.COLUMN_ID + "="+ id + " and " + selection, selectionArgs);
              }
              //add by devin 2025-10-09
              //database.delete(TransferTable.TABLE_TRANSFER,TransferTable.COLUMN_MAIN_UPLOAD_ID + "=" + id, null);
              break;
          default:
                throw new IllegalArgumentException("Unknown URI: " + uri);
      }
     return rowsDeleted;
 }

is it possible to delete the same "main_uoload_id" when deleting the database field TRANSFER_ID from the source code ?
