index upgrade tool for /dev-tools [LUCENE-2893] #3967

Open asfimport opened 13 years ago

asfimport commented 13 years ago

we change the index format from time to time, and people tracking trunk have to re-index.

I think we should put a (unsupported, scary) tool in /dev-tools that uses the PreflexRW Codec to serialize the index to a 3.0 index (with your old trunk version), you can then deserialize it back with the newer trunk version, to the newest StandardCodec.

this won't prevent all reindexes, but would work for changes under codec control.

mainly though, I think we could somehow add undeleteAll + this tool + apply deletes to prevent the painful reindexing of luceneutil benchmarking indexes :)

here is a patch against src/test, since it relies on test code to work.

i say we just drop the .java file in /dev-tools though, unless someone has ideas for improvements of course.

@rmuir Should we close this one too?
