Subject [jira] [Closed] (ASTERIXDB-2336) Sorting big tuples fails due to memory budget
Date Sun, 25 Mar 2018 00:54:00 GMT

     [ https://issues.apache.org/jira/browse/ASTERIXDB-2336?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Ali Alsuliman closed ASTERIXDB-2336.
------------------------------------
    Resolution: Not A Problem

After some discussion, we decided that we will leave this issue for the user to handle themselves
by setting the sort memory budget before the query that needs more memory than what the NC
is configured to have. We will keep the implementation as is to stay within the budget and
throw an exception letting the user know that they should increase the memory budget.

> Currently, when sorting data in a partition, and during merging the sorted run files,
the system throws an exception if one of the run files has a huge tuple. The reason is that
such a huge tuple will take almost the entire budget allocated for sorting. For such cases,
allow exceeding the budget in order to sort the data.
