We need records in our database to only live for a certain period of time (and we are using Bitcask). At first glance, expiry_secs seems to be exactly what we are looking for.
The problem is, these records need to be pruned when they are older than 10 days *according to date information in the record*, not the time that it was inserted. Many times we will repost events and things from the day before or a week before into riak. So if a week old entry goes in, it should only live for 3 more days before being pruned. I've noticed that people are saying map reduces over large buckets are not recommended for things like this, so what is a good way to prune off old entries when they are over 10 days old (according to date data within the record)? Please also note we will have 2 - 3 million keys in a single bucket, which needs to be pruned along with 200,000 - 250,000 keys in another bucket that also need to be pruned. Thanks!
