We don’t do any deletes in our cluster, but do set ttls of 8 days on most of the columns. After reading a bunch of earlier threads, I have concluded that I can safely set gc_grace_seconds to 0 and not have to worry about expired columns coming back to life. However, I wanted to know if there is any other downside to setting gc_grace_seconds to 0. Eg. I saw a mention of the ttl of hints set to gc_grace_seconds.
