[jira] [Updated] (CASSANDRA-12346) Gossip 2.0 - introduce a Peer Sampling Service for partial cluster views

Jeff Jirsa updated CASSANDRA-12346:

Description: 
A [Peer Sampling 
Service|http://infoscience.epfl.ch/record/83409/files/neg--1184036295all.pdf] 
is a module that provides a partial view of a cluster to dependent modules. A 
node's partial view, combined with all other nodes' partial views, combine to 
create a fully-connected mesh over the cluster. This way, a given node does not 
need to have direct connections to every other node in the cluster, and can be 
much more efficient in terms of resource management as well as information 
dissemination. Peer Sampling Services by their nature must be self-healing and 
self-balancing to maintain the fully-connected mesh.

I propose we use an algorithm based on 
[HyParView|http://asc.di.fct.unl.pt/~jleitao/pdf/dsn07-leitao.pdf], which is a 
concrete algorithm for a Peer Sampling Service. HyParView has a clearly defined 
protocol, and is reasonably simple to implement.

> Hotspot is able to optimize condition checks on `static final` fields. But 
> the compiler can only optimize if the referenced "constant" is the first

> class Foo {
>   static final boolean CONST = /* some fragment evaluating to false */;
>   
>   public void doSomeStuff(boolean param) {

>   // this code block can be eliminated

> if (!CONST && param) {

> if (param && !CONST) {
>   // this code block cannot be eliminated due to some compiler logic
> }
> 
>   }
> }
> {code}
> Linked patch changes the order in some {{if}} statements and migrates a few 
> methods to static final fields.
