[hibernate-issues] [Hibernate-JIRA] Commented: (HSEARCH-218) add indexAll( Class type ) to rebuild indexes from all data

[Sanne Grinovero (JIRA)]

    [ http://opensource.atlassian.com/projects/hibernate/browse/HSEARCH-218?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=31775#action_31775 ] 

Sanne Grinovero commented on HSEARCH-218:
-----------------------------------------

because of all changes to the backend, the "natural speed" in Search has improved in the mass indexing area and following the advice in the book and reference docs will get you acceptable timings.

There are still lots of optimizations to do, but I am beginning to think that most API changes I had in mind are not needed anymore;
I'm currently evaluating the option of adding more Lucene backends: could be selected by configuration and offer slightly different strategies to improve performance
but sharing most code with the current one in trunk.

> The implementation should be as efficient as possible,
> to cover this scenarios:
> * Developers change an entity and want to test the effect on the index structure,
>  they want do to search experiments with the new fields.
> * A production system is up(down)graded to a new(old) release,
> involving index changes.
>  (the system is "down for maintenance" but the speed is crucial)
> * Existing index is corrupted/lost. (Again, speed to recover is critical)
> * A Database backup is restored, or data is changed by other jobs.
> * Some crazy developer like me prefers to disable H.Search's event
> listeners for some reason.
>  (I wouldn't generally recommend it, but have met other people who
> have a reasonable  argument to do this)
> * A Lucene update breaks the index format (not so irrationale as they just did on trunk).
