    Description copied from interface: RegionObserver
    
    This will be called for every batch mutation operation happening at the server. This will be called after acquiring the locks on the mutating rows and after applying the proper timestamp for each Mutation at the server. The batch may contain Put/Delete. By setting OperationStatus of Mutations (MiniBatchOperationInProgress.setOperationStatus(int, OperationStatus)), RegionObserver can make Region to skip these Mutations.
    Note: Do not retain references to any Cells in Mutations beyond the life of this invocation. If need a Cell reference for later use, copy the cell and use that.
    
    Specified by:

    Parameters:
    
    c - the environment provided by the region server

  - postScannerFilterRow

public boolean postScannerFilterRow(ObserverContext<RegionCoprocessorEnvironment> e,
                                    InternalScanner s,
                                    Cell curRowCell,
                                    boolean hasMore)
                             throws IOException
```
    Description copied from interface: RegionObserver
    This will be called by the scan flow when the current scanned row is being filtered out by the filter. The filter may be filtering out the row via any of the below scenarios
    1. boolean filterRowKey(byte [] buffer, int offset, int length) returning true
    2. boolean filterRow() returning true
    3. default void filterRow(List<KeyValue> kvs) removing all the kvs from the passed List
    Note: Do not retain references to any Cells returned by scanner, beyond the life of this invocation. If need a Cell reference for later use, copy the cell and use that.
    Specified by:
    
    postScannerFilterRow in interface RegionObserver
    
    Parameters:
    
    e - the environment provided by the region server
    
    s - the scanner
    
    curRowCell - The cell in the current row which got filtered out
    
    hasMore - the 'has more' indication
    
    Returns:
    
    whether more rows are available for the scanner or not
    
    Throws:
    
    IOException
