------------------------------------
Summary: Optimize merge when index sorting is used but the index
is already sorted
Key: LUCENE-7568
URL: https://issues.apache.org/jira/browse/LUCENE-7568
Project: Lucene - Core
Issue Type: Improvement
Components: core/index
Reporter: Ferenczi Jim
When the index sorting is defined a lot of optimizations are disabled during
the merge. For instance the bulk merge of the compressing stored fields is
disabled since documents are not merged sequentially. Though it can happen that
index sorting is enabled but the index is already in sorted order (the sort
field is not filled or filled with the same value for all documents). In such
case we can detect that the sort is not needed and activate the merge
optimization.
