Subject [jira] [Updated] (IGNITE-10827) auto close iterator for query cursor when all data has been read
Date Fri, 11 Jan 2019 15:18:00 GMT

     [ https://issues.apache.org/jira/browse/IGNITE-10827?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Yury Gerzhedovich updated IGNITE-10827:
---------------------------------------
    Description: There is QueryCursorImpl class which we use as main realization of cursor
for H2 iterators. As of now we call close method explicit when we suppose that all data already
read. Will be better call close() method when iterator hasNext() method return false. Such
realization will be more safely and simple to use.  (was: There is QueryCursorImpl class which
we use as main realization of cursor for H2 iterators. As of now we call close method explicit
when we suppose that all data already read. Will be better call close() method when iterator
hasNext() method return false or when next() method of iterator throw any Exception. Such
realization will be more safely and simple to use.)
