Attaching updated patch.
[~tucu00], [~andrew.wang], thanks for the feedback.. think I addressed all your
comments. Couple of things though :
bq. prefer to use ArrayLists rather than LinkedLists
Agreed, but since the fill method takes a {{Queue}} and since {{LinkedList}}
implements {{Queue}} and not {{ArrayList}}, I feel we should stick to LLs.
bq. is using poll() instead, continuing to trigger refills while the return
value..
yup that would be cool.. thanks !!
bq. It looks like client requests will only will refill a single key. It seems
..
So, this is how it is now : if Queue doesn't exist for key (or if key has been
dropped), the next call from client will be a synchronous call to fill
{{numInitValues}} which can be different from {{numValues}}.
Now, If the client requests {{n}} values and there are {{< n}} in the queue,
ONLY those values will be drained via {{poll()}} in the synchronous call and
sent to client which is why I named the method {{getAtMost}}. My thinking is
that on the server side, if the cache size is large, and if the client gets
only 1 Key from a request, and if the client requires more, it can fire a
second req.. and there is a high probability that the next request from the
client for the same Q would return the complete batch (we can tune the refill
task to be more aggressive based on e2e testing). Also returning only 1 will
kind of guarantee that the server, if bombarded by concurrent requests won't
konk off.
