Hi,
I'd like to hear how other people are approaching the problem of
cleaning Riak buckets up at the end of unit tests for their apps.
The problem I have is that multiple tests may be run at once (by
different developers or different Jenkins' jobs or even just a
parallelised test suite) so I can't really run a blanket delete-all at
the end of the test suite, unless I use a randomly-named bucket each
time. Yet if I do that, I'm concerned the test suite may crash out prior
to the end sometimes, and then never delete that randomly-named bucket.
If secondary indexes aren't required, then the easy solution is to use a
randomly-named Bitcask bucket which has a backend configured for a
fairly short TTL.
Otherwise, I have wondered about creating buckets with a certain format,
perhaps "test-XXXXXX-YYYY-MM-DD", (x=random) and then a nightly cron
script can run to find all buckets timestamped from the previous day or
earlier, and remove them. I gather listing all buckets is an expensive
operation though, although it'll only be running on a testing Riak cluster.
So I wondered how other developers are approaching this issue?
Cheers,
Toby
