| * Mob file compaction chore in a generational batch mode test. |
| * 1. Enables batch mode for regular MOB compaction, |
| * Sets batch size to 7 regions. Enables generational mode. |
| * 2. Disables periodic MOB compactions, sets minimum age to archive to 10 sec |
| * 3. Creates MOB table with 20 regions |
| * 4. Loads MOB data (randomized keys, 1000 rows), flushes data. |
| * 5. Repeats 4. two more times |
| * 6. Verifies that we have 20 *3 = 60 mob files (equals to number of regions x 3) |
| * 7. Runs major MOB compaction. |
| * 8. Verifies that number of MOB files in a mob directory is 20 x4 = 80 |
| * 9. Waits for a period of time larger than minimum age to archive |
| * 10. Runs Mob cleaner chore |
| * 11 Verifies that number of MOB files in a mob directory is 20. |
| * 12 Runs scanner and checks all 3 * 1000 rows. |
