[jira] [Commented] (IOTDB-1575) Tsfile valueFilter cannot handle multiple pages

    [ https://issues.apache.org/jira/browse/IOTDB-1575?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17401452#comment-17401452 ] 

DaweiLiu commented on IOTDB-1575:
---------------------------------

When using valueFilter to filter data, the page's statistics are used to pre-check for conditions, but when the actual data does not exist, BatchData returns a container that does not have any data.


The LeafNode checks the BatchData, and if hasCurrent returns false, the query is broken and we actually need to continue to the next page
