One big bucket or many small bucket, which is better?
I'm newbie in Membase, please advise me this problem: I have data with two hundred million keys (2000 bytes per key) and I don't know how to setup bucket to have good performance:
A. Use 1 bucket which contain 200 million keys
B. Use 5 bucket which contain 40 million keys
--> which is better?
I heard someone said Membase will slow if it has too many keys, is that true?
