> In order to prevent race conditions when multiple client try to mutate the
> same column before sending the request to mutate the column to the server do
> a checkAndMutate with the column name being added/dropped. Also:
> 1. When a view is created do a checkAndMutate with the columns in the view
> where clause.
> 2. When an index on a view is created do a checkAndMutate with the indexed
> columns.
>
> To prevent a race condition in the DROP TABLE CASCADE case, when a table is
> dropped do a checkAndMutate with the rowkey of the base table name. If a view
> is created it also does a checkAndMutate with the same rowkey.
