>  (item 2), we must check whether a schema effective at operationTs (for each 
> read/write operation in an RW transaction) is different from the initial 
> schema (at the beginning of the transaction for the table). If it's 
> different, we should throw an exception (that will cause the transaction to 
> be aborted).
