Operation prepare(TableMetadata metadata,
                  ColumnMetadata receiver,
                  boolean canReadExistingState)
           throws InvalidRequestException
```
    This method validates the operation (i.e. validate it is well typed) based on the specification of the receiver of the operation. It returns an Operation which can be though as post-preparation well-typed Operation.
    
    Parameters:
    
    metadata -
    
    receiver - the column this operation applies to.
    
    canReadExistingState - whether the update depends on existing state
    
    Returns:
    
    the prepared update operation.
    
    Throws:
    
    InvalidRequestException
  - isCompatibleWith
```
boolean isCompatibleWith(Operation.RawUpdate other)
```
    Returns:
    
    whether this operation can be applied alongside the other update (in the same UPDATE statement for the same column).
