Another comment I also tried an implementation of the test code where delete waited in a loop as long as the tombstone was still there. But as far as I can see it might then wait forever. Or at least several minutes - until I did not care to wait any longer.
Is that so - an a tombstone exist forever? /Roland ----- Original Message ----- From: "Jon Meredith" <[email protected]> To: "Roland Karlsson" <[email protected]> Cc: [email protected] Sent: Monday, October 3, 2011 5:02:27 PM Subject: Re: Delete takes 5 seconds in riak 1.0 ??? Hi Roland, Riak deletes by first writing a tombstone and then when all replicas are in sync removing the object from the underlying key/value store. We have made some changes in 1.0.0 to increase the length of time the tombstones are around when all nodes are up (in the Delete Changes section of the release notes here https://github.com/basho/riak/blob/1.0/RELEASE-NOTES.org ). If you just want to make sure the object is deleted, you could use the deletedvclock option on the get request. You will get a 3-tuple {error, notfound, VClock} until the tombstone is removed, then a 2-tuple of {error, notfound} when it has gone. If you wish to rewrite the key, you can use the returned vclock on a new object O = riakc_obj:set_vclock(riakc_obj:new(<<"b">>,<<<"k">>,<,"v">>), VClock) and it will overwrite the tombstone for you.

The tests are attached to this mail. In particular I made this call in the tests at the start of of each test in order to get a clean DB. riakc_pb_socket:delete(Pid, Bucket, Key), In 0.14 that worked just fine. But ... in 1.0 it did not work. The tests failed and complained about siblings. But ... after some time of experimenting I found that if I added a sleep of 5 seconds after the delete ... then the tests were OK again. Is this correct? Does delete take 5 seconds?
