There are many occasions when I need to quickly refer to the programming APIs when I am trying something new. For my personal use, I created one handy Couchbase Server 1.8.1 Java Cheat Sheet, which I hang on my desk always.
This cheat sheet helped me quite a bit and has saved me from getting annoyed of looking up for same APIs again and again. It is designed to act as a reminder and reference sheet, listing useful information about the Couchbase Server 1.8.1 Java SDK. You can download the cheat sheet here.
