    从接口复制的说明: RegionObserver
    
    Called after a new cell has been created during an increment operation, but before it is committed to the WAL or memstore. Calling ObserverContext.bypass() has no effect in this hook.
    
    指定者:
    
    postMutationBeforeWAL 在接口中 RegionObserver
    
    参数:
    
    ctx - the environment provided by the region server
    
    opType - the operation type
    
    mutation - the current mutation
    
    oldCell - old cell containing previous value
    
    newCell - the new cell containing the computed value
    
    返回:
    
    the new cell, possibly changed
    
    抛出:

```
    从接口复制的说明: 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.
    指定者:
    
    postScannerFilterRow 在接口中 RegionObserver
    
    参数:
    
    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
    
    返回:
    
    whether more rows are available for the scanner or not
    
    抛出:
