Here are the scenarios:
1. Update via primary index, partition column specified - checks only one partition on one amp
2. Update via primary index, partition columns not specified - checks for all partitions on one amp.
3. All rows update - partition column specified - scans only one partition on all amps
4. All rows update - partition column not specified - scans all rows.
