that would be expensive to create a new txnStore everytime

> When a CTAS query fails before creation of table and after writing the data,
> the data is present in the directory and not cleaned up currently by the
> cleaner or any other mechanism currently. This is because the cleaner
> requires a table corresponding to what its cleaning. In order surpass such a
> situation, we can directly pass the relevant information to the cleaner so
> that such uncommitted data is deleted.
