[jira] [Commented] (LUCENE-10017) Do not check footers on Lucene7x
segments when throwing IndexFormatTooOld
[ https://issues.apache.org/jira/browse/LUCENE-10017?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17373075#comment-17373075 ]

------------------------------------
I'm not sure if this is "blocker" level but I really would want this considered before we make a 9.0 release.

> Key: LUCENE-10017
> URL: https://issues.apache.org/jira/browse/LUCENE-10017
> Project: Lucene - Core
> Issue Type: Improvement
> Components: core/index
> Affects Versions: main (9.0)
> Reporter: Mike Drob
> Priority: Major
>
> Ran into this while investigating how to improve the logging situation in SOLR-15516
> When we throw an IndexFormatTooOldException when attempting to read a segment, we will read still attempt to read the footer since it is newer than 7x (which AFAIUI was the oldest version to support these footers?)
> We should update that to only check footers for versions newer than 8x, otherwise we create a needless additional exception.
