Hi, I was writing a utility to change a partition key in a Column Family. The way I'm doing it is by constructing a temporary table in the background that has the new configuration(partition key), and then swap them instantly with the original table by physically swapping SSTables files, and updating and reloading the new schema. My question is, in order to prevent undefined behavior when I'm swapping the SSTables files and updating the schema, is it possible to block the write operations on a Column Family across the cluster? I might also need to block the read requests, but I figured having undefined behavior in write path is more undesirable.
Thank you! Sincerely, Yosub -- Yosub Shin Candidate for B.S. in Computer Science, University Of Illinois shi...@illinois.edu 515-999-6782
