Sorry I now realized that I used the wrong terminology.

What I really meant was, moving or copying the ROWS defined by a KeyRange in between ColumnFamilies.
Do you think it's doable with an efficient way?

There are no single API call to achieve this.

 

It’s read and write, plus a delete (if move) API calls I guess.

Subject: Moving/copying columns in between ColumnFamilies

 

Hey All,

Assume I have two ColumnFamilies in the same keyspace and I want to move or copy a range of columns (defined by a keyrange) into another columnfamily.

Do you think it's somehow possible and doable with the current support of the API, if so how?

Best Regards,
