Stop creating huge arrays to represent the absense of field norms
-----------------------------------------------------------------
Key: LUCENE-1604
URL: https://issues.apache.org/jira/browse/LUCENE-1604
Project: Lucene - Java
Issue Type: Improvement
Components: Index
Affects Versions: 2.9
Reporter: Shon Vella
Priority: Minor
Creating and keeping around huge arrays that hold a constant value is very
inefficient both from a heap usage standpoint and from a localility of
reference standpoint. It would be much more efficient to use null to represent
a missing norms table.
