[GitHub] [lucene-solr] s1monw opened a new pull request #2221: LUCENE-9669: Restore Lucene70Codec
s1monw opened a new pull request #2221:
URL: https://github.com/apache/lucene-solr/pull/2221
This change restores the Lucene70Codec for file format compatibility of
indices that are created within the Lucene 7 major version. These indices
can be opened via an expert API on DirectoryReader in read-only mode. Changes
to these indices are prohibited and will be rejected by the IndexWriter.
In fact, IndexWriter will not open an index that is created with a major version
less than N-1 to the current major version.
