RateLimiter (Jackrabbit Oak 1.78.0 API)

java.lang.Object
- org.apache.lucene.store.RateLimiter

Direct Known Subclasses:

RateLimiter.SimpleRateLimiter
```
public abstract class RateLimiter
extends Object
```
Abstract base class to rate limit IO. Typically implementations are shared across multiple IndexInputs or IndexOutputs (for example those involved all merging). Those IndexInputs and IndexOutputs would call pause(long) whenever they want to read bytes or write bytes.

- Method Detail
  - setMbPerSec
```
public abstract void setMbPerSec(double mbPerSec)
```
    Sets an updated mb per second rate limit.
  - getMbPerSec
```
public abstract double getMbPerSec()
```
    The current mb per second rate limit.
  - pause
```
public abstract long pause(long bytes)
```
    Pauses, if necessary, to keep the instantaneous IO rate at or below the target.
    Note: the implementation is thread-safe
