| <div class="block">Defines a protocol to delete data in bulk based on a scan. The scan can be range scan or with |
| conditions(filters) etc.This can be used to delete rows, column family(s), column qualifier(s) |
| or version(s) of columns.When delete type is FAMILY or COLUMN, which all family(s) or column(s) |
| getting deleted will be determined by the Scan. Scan need to select all the families/qualifiers |
| which need to be deleted.When delete type is VERSION, Which column(s) and version(s) to be |
| deleted will be determined by the Scan. Scan need to select all the qualifiers and its versions |
| which needs to be deleted.When a timestamp is passed only one version at that timestamp will be |
| deleted(even if Scan fetches many versions). When timestamp passed as null, all the versions |
| which the Scan selects will get deleted. |
| |
| <br> Example: <pre><code> |
| Scan scan = new Scan(); |
| // set scan properties(rowkey range, filters, timerange etc). |
| HTable ht = ...; |
| long noOfDeletedRows = 0L; |
| Batch.Call<BulkDeleteService, BulkDeleteResponse> callable = |

| |
| public BulkDeleteResponse call(BulkDeleteService service) throws IOException { |
| Builder builder = BulkDeleteRequest.newBuilder(); |
| builder.setScan(ProtobufUtil.toScan(scan)); |
| builder.setDeleteType(DeleteType.VERSION); |
| builder.setRowBatchSize(rowBatchSize); |
| // Set optional timestamp if needed |
| builder.setTimestamp(timeStamp); |
| service.delete(controller, builder.build(), rpcCallback); |
| return rpcCallback.get(); |
| } |
| }; |
| Map<byte[], BulkDeleteResponse> result = ht.coprocessorService(BulkDeleteService.class, |
