[jira] [Commented] (ASTERIXDB-1841) Dropping a large inverted index
generates an exception
[ https://issues.apache.org/jira/browse/ASTERIXDB-1841?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15930466#comment-15930466 ]
Till commented on ASTERIXDB-1841:
---------------------------------
[~wangsaeu] Does the size of the inverted index matter? Looking at the subject seems to suggest that it might, but looking at the stack trace it seems that it shouldn't.
