Hi I have the same problem with Couchbase, I had 1 instance of MongoDB with over 1.4 billion of data. I decided to change our databases to Couchbase with Elasticsearch indexing. I have 8 VPS ( 10 * 2.2 GHz cores, 50g RAM, 1.2T SSD ) , and I used 3 of them (totally 120g RAM allocated) to store data on couchbase without any Indexing, ( Reading from MongoDB, make json flat and just Inserting to Couchbase ). all of 3 Couchbase nodes alarming : Hard Out Of Memory Error. Bucket "MYBUCKET" on node www.xxx.yyy.zzz is full. All memory allocated to this bucket is used for metadata. and the number of OP/Sec is decreasing to fully useless ( it's changing between 0 to maximum 200). so what I have to do to make the system stable and without warnings and errors. Thank you.
