[infinispan-issues] [JBoss JIRA] (ISPN-2889) AbstractIterator shouldn't allocate a larger result array than is necessary

Marko Lukša created ISPN-2889: --------------------------------- Summary: AbstractIterator shouldn't allocate a larger result array than is necessary Key: ISPN-2889 URL: https://issues.jboss.org/browse/ISPN-2889 Project: Infinispan Issue Type: Enhancement Components: Querying Reporter: Marko Lukša Assignee: Marko Lukša Currently {{AbstractIterator}} (superclass of LazyIterator and EagerIterator) always allocates an {{Object[]}} array of size {{fetchSize}}, even when the actual number of results is smaller than {{fetchSize}}. This is especially problematic when the user wants to fetch all the results at once (by setting fetchSize to a very large number such as Integer.MAX_VALUE). This results in an OutOfMemoryError: Requested array size exceeds VM limit. Since the number of results is known up-front, {{AbstractIterator}} can allocate a smaller array. -- This message is automatically generated by JIRA.
