We’re using Couchbase 1.8.1 cluster on four 32Gb nodes and we need to dump the keys from the bucket that has 180 million entries. The bucket is all the time under load (about 5000 get requests and about 100 put requests per second), most of the keys are in memory (cache miss is about 2%).
We’re going to use Couchbase Java TAP client to dump the keys, but there are all these “While not fully supported… which would cause lots of memory usage or resource consumption if you’re not careful” sound very dangerous.
We’d like to be as much “careful” as possible! Does anyone have any tips of advices on how to do this without bringing the performance down?
Thanks a lot,
