Hi all! I have a fairly trivial question regarding mass deletion on a riak cluster, but firstly let me give you just some context. My cluster is running with riak 1.4.6 on 6 machines with a ring of 256 nodes and 1Tb ssd disks.
I need to execute a massive object deletion on a bucket, I'm talking of ~1 billion keys (The object average size is ~1Kb). I will not retrive the keys from riak because a I have a file with all of them. I'll just start a script that reads them from the file and triggers an HTTP DELETE for each one. The cluster will continue running on production with a quite high load serving all other applications, while running this deletion. My question is simple, do I need to have any kind of extra concerns regarding this action? Do you advise me on taking special attention to any kind of metrics regarding riak or event the servers where it's running? Best regards!
