Versions: 1.6.5 and 188.8.131.52
2 Membase buckets: 1. 24000 MB and the 2. 1000MB
Quota for Membase set to 25000MB
Dedicated Membase Server 8 Core CPU 32GB RAM
Inserted data total 201 million key/values.
Problem is after 150 million key/values sets performance went very bad down, server started to swap strong and response times were more than bad, mysql can better with the perfect setting.
I thought Membase can handle over 10K QPS but seems it can 1K QPS in a live system where good response times are required. Until 150 million key/values between 3K and 10k without any problems reached, but above went really bad.
Tested both membase releases!
I set the qouta to 25000 MB which is round 75% from the dedicated RAM so should be fine from setting or not.
Now I am thinking to use only memcached bucket but hope I don't get the same surprise like the membase bucket.
If you have suggestions, questions about my experience or share your experience with the membase server are welcome.
