Arun Suresh commented on HADOOP-10720:
--------------------------------------
So, {{initValue}} is actually the number of values that are synchronously
pushed into a key's queue, when it is first created (when Cache's {{load}}
method is called / or when a warmup is requested) and {{lowWatermark}} is
threshold below which for an existing key's Queue, will be asynchronously
filled. I have 2 constructors, one that takes an {{numInitValues}} (which I
used on the server) and one that assumes {{numInitValues}} = {{numValues}}
(which I used for the client). My assumption was that the Server would cache a
lot more values of a key, so initValues can be less than numValues.
A {{SyncGenerationPolicy.ATLEAST_ONE / INIT_VALUE / LOW_WATERMARK / ALL}}
policy just states that when a client calls the {{getAtMost(n)}}, at least {{1
/ initValue / lowWaterMark / n}} entries are returned synchronously.
I guess the confusion was due to the placement of the comments. Also : yes, I
think I should remove the INIT_VALUE policy and constructor parameter all
together and assume the initializationValue for a Queue is {{lowWatermark}}.
