["Jacques Nadeau (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/DRILL-3986?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14977500#comment-14977500 ] 

Jacques Nadeau commented on DRILL-3986:
---------------------------------------

For a reasonable overview of value vectors, see here (not that this is slightly out of date versus the code, specifically in the context of the repeated value construction):

https://drill.apache.org/docs/value-vectors/

The current base interface for value vectors: 

https://github.com/apache/drill/blob/master/exec/java-exec/src/main/java/org/apache/drill/exec/vector/ValueVector.java

> We'd like to look at extracting value vector functionality into a new submodule. We're probably going to have to do some subdivisions of responsibility to figure out what should be extracted and what is Drill specific. This is an umbrella JIRA to track extracting this functionality.
