| <div class="block">Helper to Restore/Clone a Snapshot |
| |
| <p>The helper assumes that a table is already created, and by calling restore() |
| the content present in the snapshot will be restored as the new content of the table. |
| |
| <p>Clone from Snapshot: If the target table is empty, the restore operation |
| is just a "clone operation", where the only operations are: |
| <ul> |
| <li>for each region in the snapshot create a new region |
| (note that the region will have a different name, since the encoding contains the table name) |
| <li>for each file in the region create a new HFileLink to point to the original file. |
| <li>restore the logs, if any |
| </ul> |
| |
| <p>Restore from Snapshot: |
| <ul> |
| <li>for each region in the table verify which are available in the snapshot and which are not |
| <ul> |
| <li>if the region is not present in the snapshot, remove it. |
| <li>if the region is present in the snapshot |
| <ul> |
| <li>for each file in the table region verify which are available in the snapshot |
| <ul> |
| <li>if the hfile is not present in the snapshot, remove it |
| <li>if the hfile is present, keep it (nothing to do) |
| </ul> |
| <li>for each file in the snapshot region but not in the table |
| <ul> |
| <li>create a new HFileLink that point to the original file |
| </ul> |
| </ul> |
| </ul> |
| <li>for each region in the snapshot not present in the current table state |
| <ul> |
| <li>create a new region and for each file in the region create a new HFileLink |
| (This is the same as the clone operation) |
| </ul> |
| <li>restore the logs, if any |
