-------------------------------------------
Hi Pavel,
I have added the long count operator to ProcessResultOperatorsBegin. Right now,
I am trying to create unit tests for it, but I am having some problems. One
thing I would like to test is the ability to return a long count when the
cache's size is more than int.MaxValue, but when I try to insert large amount
(e.g. long.MaxValue) of data into the cache, it throws a
*CachePartialUpdateException* saying that it fails to update keys. More detail
is at the end. I wonder if I should do that and if adding large amount of data
into the cache for unit testing is a good thing? or do you think using small
set of data is enough to test the functionality?
Please let me know.
Thanks,
Nathan

> .NET: Support LongCount in LINQ

> Project: Ignite
> Issue Type: Improvement
> Components: platforms
> Reporter: Pavel Tupitsyn
> Assignee: Kin (Nathan) Chan
> Priority: Major
> Labels: .NET, LINQ, newbie
>
> H2 SQL {{COUNT}} function returns a {{long}}, but LINQ {{Count}} returns an
> int. We should simply add {{LongCount}} support the same way as {{Count}}.
> The tricky thing would be to test it.
