             Summary: Fix linefiledocs compression or replace in tests
                 Key: LUCENE-9191
                 URL: https://issues.apache.org/jira/browse/LUCENE-9191
             Project: Lucene - Core
          Issue Type: Task
            Reporter: Robert Muir


LineFileDocs(random) is very slow, even to open. It does a very slow "random skip" through a gzip compressed file.

For the analyzers tests, in LUCENE-9186 I simply removed its usage, since TestUtil.randomAnalysisString is superior, and fast. But we should address other tests using it, since LineFileDocs(random) is slow!

I think it is also the case that every lucene test has probably tested every LineFileDocs line many times now, whereas randomAnalysisString will invent new ones.

Alternatively, we could "fix" LineFileDocs(random), e.g. special compression options (in blocks)... deflate supports such stuff. But it would make it even hairier than it is now.
