I can take a look at partial upsert handler and provide a potential
optimization.
We might ignore and avoid accessing null values during 'merging' to reduce
disk I/O.
@Jackie-Jiang Do you think this will be helpful?
@ankitsultana I think this issue can happen when there are too many columns
in a high throughput kafka topic.
do we have metrics on disk IO metric for this table?
