Subject [jira] [Commented] (CASSANDRA-3883) CFIF WideRowIterator only returns batch size columns
Date Mon, 13 Feb 2012 14:06:59 GMT


Brandon Williams commented on CASSANDRA-3883:

My original description here is incorrect; I can't repro the 198 count (not sure what happened
there) but now the wide row tests counts 1033 'word1' items.  As far as I can tell, WordCountSetup
actually inserts a total of 2002 'word1' matches, one in each of text1 and text2, and a thousand
in each of text3 and text4.  I'm not sure what is causing the count discrepancy, but in any
case 1033 is far above the batch size of 99, and and the 4th word count test using a secondary
index is counting 197 items, so I think something may be fundamentally wrong with word count.

That said, I've been adding wide row support to pig and testing with that, and the problem
of not being able to completely paginate wide rows is a definite problem.

> Most evident with the word count, where there are 1250 'word1' items in two rows (1000
in one, 250 in another) and it counts 198 with the batch size set to 99.
