Review Comment:
All the segment operation throttlers extend from
`BaseSegmentOperationsThrottler`, and this class contains the main logic for
updating the configs and acquire / release of the semaphore. I pass in the
gauges here because each throttler has it's own gauge for threshold and count.
I thought this would be cleaner than adding if-else conditions.
Do you have any other recommendations other than passing them in? Other
option I could think of is adding methods for updating the gauge and have the
extenders implement them to set the value, while having the
`BaseSegmentOperationsThrottler` call into these methods. something like:
```
void updateThresholdGauge(int valueToSet);
void updateCountGauge(int valueToSet);
```
wdyt?
