> We currently provide basic names for threads in threads like {{STREAM-IN-1}}  which gives some basic information about what the job of the thread is.  
> When looking at a log statement or jstack it's helpful to have this context.
> For our work stealing thread pool we share threads across all thread pools so we lose this insight.  
> I'd like to propose we start using the Thread.currentThread().setName("")
> In different aspects of the code to improve insight as to what cassandra is doing at any given moment.
>    * At a minimum in the start of each run() method.
>   Ideally for much finer grain things.
>    * In compaction include the partition name currently being working on.  
>    * In SP include the client ip
> Etc...
