问题
I need to clear a Couchbase bucket each time before unit test runs. I use the Java SDK > 2.0 version. In previous versions I found this wonderful method http://www.couchbase.com/autodocs/couchbase-java-client-1.1.1/com/couchbase/client/ClusterManager.html#flushBucket(java.lang.String) but it does not exist in new version.
Is there some way to clear data from bucket? I could delete by fetching all keys of documents and then delete them all, but I want to use more pretty way.
回答1:
Actually in the 2.x SDK you can get a BucketManager out of a Bucket instance, which will allow you to call flush() as wonderfully as before ;)
回答2:
Mind that it might be risky to flush and use N1QL queries afterwards in Community v4.0. My integration tests were failing because some documents didn't get indexed after a few dozens of runs (even after 30 minutes). It's safer to just delete documents.

You could use the REST API to delete the bucket: http://docs.couchbase.com/admin/admin/REST/rest-bucket-intro.html
回答4:
In the Couchbase Java 2.x SDK API Reference look at BucketFlusher.
