Subject [jira] Commented: (LUCENE-1654) Include diagnostics per-segment when writing a new segment
Date Tue, 26 May 2009 16:32:47 GMT

    [ https://issues.apache.org/jira/browse/LUCENE-1654?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12713086#action_12713086

Earwin Burrfoot commented on LUCENE-1654:
-----------------------------------------

bq. It's the reading side of that API that makes me nervous (SegmentInfo/s is not public).
No-no-no, don't open it up, it's suicidal :)

We can theoretically allow access to per-segment data from segment readers, as they have 1-1
relation.
So, when I finish always-use-MSR patch, you should be able to get per-commit data from MSR
and per-segment from SR using the same API. Sounds somewhat dirty, but would work well...
needs more thought.

> It would be very helpful if each segment in an index included

> We can start with just the current version.
> We could also consider making this extensible, so you could provide

> CheckIndex to check on it later.  Or we could wait on such extensibility
