Summary: Create a Lucene70DocValuesFormat
Key: LUCENE-7463
URL: https://issues.apache.org/jira/browse/LUCENE-7463
Project: Lucene - Core
Issue Type: Improvement
Reporter: Adrien Grand
Priority: Minor
Fix For: 7.0
Even if it is not optimal, I think it would help to create a
Lucene70DocValuesFormat now by copying the current Lucene54DocValuesFormat and
including some minor changes like making the sparse case use a true iterator
API as described in LUCENE-7457 (which should make it to
Lucene54DocValuesFormat a well so that merging from an old codec would be
efficient) as well as raising the threshold to enable sparse encoding and using
nextSetBit operations when iterating bit sets, which cannot be done easily in
Lucene54DocValuesFormat because we'd need to add a couple trailing bytes to
make sure we can read a long at any valid index.
