  - checkQuota
```
public void checkQuota(int numWrites,
              int numReads,
              int numScans)
                throws ThrottlingException
```
    Description copied from interface: OperationQuota
    
    Checks if it is possible to execute the specified operation. The quota will be estimated based on the number of operations to perform and the average size accumulated during time.
    
    Specified by:
    
    checkQuota in interface OperationQuota
    
    Parameters:
    numWrites - number of write operation that will be performed
    numReads - number of small-read operation that will be performed
    numScans - number of long-read operation that will be performed
    
    Throws:
    
    ThrottlingException - if the operation cannot be performed
  - close
```
public void close()
```
    Description copied from interface: OperationQuota
    
    Cleanup method on operation completion
    
    Specified by:
    
    close in interface OperationQuota
  - addGetResult
```
public void addGetResult(Result result)
```
    Description copied from interface: OperationQuota
    
    Add a get result. This will be used to calculate the exact quota and have a better short-read average size for the next time.
    
    Specified by:
    
    addGetResult in interface OperationQuota
  - addScanResult
```
public void addScanResult(List<Result> results)
```
    Description copied from interface: OperationQuota
    
    Add a scan result. This will be used to calculate the exact quota and have a better long-read average size for the next time.
    
    Specified by:
    
    addScanResult in interface OperationQuota
  - addMutation
```
public void addMutation(Mutation mutation)
```
    Description copied from interface: OperationQuota
    
    Add a mutation result. This will be used to calculate the exact quota and have a better mutation average size for the next time.
    
    Specified by:
    
    addMutation in interface OperationQuota
  - getReadAvailable
```
public long getReadAvailable()
```
    Specified by:
    
    getReadAvailable in interface OperationQuota
    
    Returns:
    the number of bytes available to read to avoid exceeding the quota
  - getWriteAvailable
```
public long getWriteAvailable()
```
    Specified by:
    
    getWriteAvailable in interface OperationQuota
    
    Returns:
    the number of bytes available to write to avoid exceeding the quota
