Old thread, but we're still running into similar issues in 2014 (possibly due to https://github.com/basho/riak_kv/issues/311)
In case it helps anyone, here's a quick ruby script to crawl through and remove the tombstones *use at your own risk* - you're not supposed to list all keys in production, but for us the alternative was to have 560K tombstones sitting around taking up space when we only needed ~3K active keys. Toss this in a monthly cron job and there you go - also, if you needed the script to use less memory you could alter the first curl request to: `curl 'localhost:8098/buckets/YOUR_BUCKET_HERE/keys?keys=stream > /tmp/tmp_file.json` and then parse the resulting JSON file one chunk at a time. Note that the ?pw=all&pr=all&w=all&r=all is necessary (as per this thread). riak_tombstone_cleanup.rb ----------------- require 'json' puts "Getting list of riak keys" keys = JSON.parse(`curl 'localhost:8098/buckets/YOUR_BUCKET_HERE/keys?keys=true'`)['keys'] puts "#{keys.count} keys loaded" bad_keys_counter = 0 good_keys_counter = 0 keys.each do |key| result = `curl -I 'localhost:8098/buckets/YOUR_BUCKET_HERE/keys/#{key}?pw=all&pr=all&w=all&r=all' 2>&1` if result['404 Object Not Found'] bad_keys_counter += 1 else good_keys_counter += 1 end puts "Processed #{bad_keys_counter} bad key(s) and #{good_keys_counter} good key(s)" if (bad_keys_counter + good_keys_counter) % 1000 == 0 end -- View this message in context: http://riak-users.197444.n3.nabble.com/Problem-with-deleting-keys-tp3069985p4031578.html Sent from the Riak Users mailing list archive at Nabble.com. _______________________________________________ riak-users mailing list riak-users@lists.basho.com http://lists.basho.com/mailman/listinfo/riak-users_lists.basho.com
