[jira] [Commented] (CASSANDRA-3883) CFIF WideRowIterator only returns batch size columns

["Brandon Williams (Commented) (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/CASSANDRA-3883?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13206502#comment-13206502 ] 

Brandon Williams commented on CASSANDRA-3883:
---------------------------------------------

At least one problem here is that after retrieving the first page of a row, we set the startToken to the token of the last row:
{noformat}
startToken = partitioner.getTokenFactory().toString(partitioner.getToken(lastRow.key));
{noformat}

which is exclusive and thus advances to the next row, without completely paging through the first.

> 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.
