I think the "apply streaming transaction worker" is a good option
w.r.t. what we are currently doing but then in the future, if we want
to apply normal transactions in parallel then we will have to again
change the name. So I think "apply parallel worker" might look
better and the file name could be "applyparallelworker.c" or just
"parallelworker.c". Although "parallelworker.c" file name is a bit
generic but we already have worker.c so w.r.t that "parallelworker.c"
should just look fine. At least that is what I think.
