Review Comment:
Sounds good. Then, we may need to change the logic to use only 1 config.
1. Pick `minRecordCount` configuration. If no configuration is provided, we use default value for minRecordCount.
2. If `thresholdPercent` is configured, we override the behavior to pick up `thresholdPercent`. If both record/percent are provided, we use percent.
@Jackie-Jiang Does this sound good to you?

Review Comment:
Let's change the logic to compute based on the `invalidRecordCount` instead of `invalidRecordPercent`.
We can set the `invalidRecordsThresholdCount` to be
```
long invalidRecordsThresholdCount;
if (percent config is used) {
invalidRecordsThresholdCount = segment.getTotalDocs() * config.(PERCENT_CONFIG) // use some rounding
} else {
invalidRecordsThresholdCount = config.get(COUNT_CONFIG); // if this is null, use default count config (e.g. 10k)
}
```
