Mob file compaction chore in a regular batch mode test. 1. Enables batch mode for regular MOB
compaction, Sets batch size to 7 regions. 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.
