(defn chain
  "Composes functions, left to right, over the value `x`, returning a promise containing
   the result.  When composing, either `x` or the returned values may be values which can 
   be converted to a promise, causing the composition to be paused.

   The returned promise will only be realized once all functions have been applied and their
   return values realized.

Writing Resilient Reactive Applications

This guide is a first draft (that will end up in the official docs) on writing resilient code for production with the Couchbase Java SDK. At the end, the reader will be able to write code that withstands bugs, latency issues or anything else that can make their application fail.

Note that lots of concepts can be applied for both synchronous and asynchronous access. When necessary, both patterns are discussed separately. Also, the focus is on database interaction, but if you are using RxJava as part of your stack you can apply most of the principles there as well (and should!).

RxJava 101 Recap: Cold and Hot Observables

When working with Observables, it is important to understand the difference between cold and hot. Cold Observables will start to emit events once a Observer subscribes, and will do it "fresh" for each Observer. Hot Observables instead are starting to emit data as soon as it becomes available, and will return the same (or parts of the same)

 * Given an operation that produces a T, returns a Future containing the result of T, unless an exception is thrown,
 * in which case the operation will be retried after _delay_ time, if there are more possible retries, which is configured through
 * the _retries_ parameter. If the operation does not succeed and there is no retries left, the resulting Future will contain the last failure.

JDK 8 Released

Most of us won’t be able to use/deploy JDK 8 in production for a looong time. But that shouldn’t stop us from using it, right?

It should be possible to sneak in JDK 8 in the back way, the same way we snuck in Groovy and other libraries we wanted to use.

The Test Suite to the rescue

The Maven compiler plugin run in two separate lifecycles, compile and testCompile. Those can be configured separately.
