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