All old lucene index will be ignored and new index will be generated right after the restart. The old index won't be cleaned by intention until next version, in case users may want to roll back. > * What will happen to the segments with existing lucene index? > * Do we need to regenerate lucene index on-the-fly for all the segments on the server during segment load? > * How costly it is to regenerate the index? > * Are we able to clean up the old lucene index? > > IMO the much safer solution would be to introduce a new version to achieve the migration, similar to how raw index is upgraded. -- This is an automated message from the Apache Git Service.
