A factory for RateLimiters which apply rate-limiting to a source sub-task.

Method Summary

All Methods Static Methods Instance Methods Abstract Methods
Modifier and Type	Method	Description
`RateLimiter`	`createRateLimiter(int parallelism)`	Creates a `RateLimiter` that lets records through with rate proportional to the parallelism.
`static RateLimiterStrategy`	`noOp()`	Creates a convenience `RateLimiterStrategy` that is not limiting the records rate.
`static RateLimiterStrategy`	`perCheckpoint(int recordsPerCheckpoint)`	Creates a `RateLimiterStrategy` that is limiting the number of records per checkpoint.
`static RateLimiterStrategy`	`perSecond(double recordsPerSecond)`	Creates a `RateLimiterStrategy` that is limiting the number of records per second.

- Method Detail
  - createRateLimiter
```
RateLimiter createRateLimiter(int parallelism)
```
    Creates a RateLimiter that lets records through with rate proportional to the parallelism. This method will be called once per source subtask. The cumulative rate over all rate limiters for a source must not exceed the rate limit configured for the strategy.
  - perSecond
```
static RateLimiterStrategy perSecond(double recordsPerSecond)
```
    Creates a RateLimiterStrategy that is limiting the number of records per second.
    
    Parameters:
    
    recordsPerSecond - The number of records produced per second. The actual number of produced records is subject to rounding due to dividing the number of produced records among the parallel instances.
  - perCheckpoint
```
static RateLimiterStrategy perCheckpoint(int recordsPerCheckpoint)
```
    Creates a RateLimiterStrategy that is limiting the number of records per checkpoint.
    
    Parameters:
    
    recordsPerCheckpoint - The number of records produced per checkpoint. This value has to be greater or equal to parallelism. The actual number of produced records is subject to rounding due to dividing the number of produced records among the parallel instances.
  - noOp
```
static RateLimiterStrategy noOp()
```
    Creates a convenience RateLimiterStrategy that is not limiting the records rate.
