Cassandra COPY TO with timestamp

Question

My goal is to move rows from one Cassandra 2.0 table to another with different primary key. To ensure data consistency I will need to insert them with original timestamps (USING TIMESTAMP). I planed to use COPY TO/COPY FROM or just COPY TO and custom import from CSV.

Is there a way to copy rows with timestamps? unixTimestampOf() on TimeUUID column doesn't work saying "Improper COPY command".

Thanks in advance.

Answer 1

It's impossible to do so using COPY TO/FROM. But it's possible to obtain a timestamp for a column using WRITETIME function
