Subject [jira] [Commented] (IGNITE-1544) Make sure objects number stored in a cache can be bigger than Integer.MAX_VALUE
Date Wed, 25 Nov 2015 08:31:11 GMT

    [ https://issues.apache.org/jira/browse/IGNITE-1544?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15026415#comment-15026415

Denis Magda commented on IGNITE-1544:
-------------------------------------

Andrey, I have the following comments so far:

1. Let's go further and remove {{GridCacheAdapter.primarySize()}} or make it return {{long}}
by default. Since it's the internal API I don't see any reason why we need to introduce {{primarySizeLong}}
counterpart;

2. {{GridCacheAdapter.sizeAsync}} and {{GridCacheAdapter.sizeLongAsync}} method's implementation
body is the same. The only difference is that one uses {{SizeTask}} while the other - {{SizeLongTask}}.
I suggest moving common part of the implementations in a special private method which will
accept a size task as a parameter.

3. In the newly added java docs there is the sentence like this - "Gets the number of all
entries cached on this node as a long". Please end such sentences with "as a long value" instead.

> Make sure that a cache (partitioned) can actually hold number of objects bigger than
{{Integer.MAX_VALUE}}. Because {{Integer.MAX_VALUE}} is not enough for some life use cases
and business domains.
> At least the following should be done:
> - IgniteCache must return cache size as a {{long}} value;
> - Make sure (make a test) that a partitioned cache can store number of objects much bigger
than {{Integer.MAX_VALUE}};
> - find and edit info regarding this limitation.
