Subject [jira] [Commented] (LUCENE-4591) Make StoredFieldsFormat more configurable
Date Thu, 06 Dec 2012 15:55:17 GMT

    [ https://issues.apache.org/jira/browse/LUCENE-4591?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13511475#comment-13511475
] 

Robert Muir commented on LUCENE-4591:
-------------------------------------

As I said before, In my opinion all (or at least most) codec components should take segment
suffixes and respect them.

I actually have a nocommit for this in LUCENE-4547 branch.

I was thinking we could even have a test for this, that writes a segment directly to all the
consumers with a suffix and then
checks the filenames and so on.

> The current StoredFieldsFormat are implemented with the assumption that only one type
of StoredfieldsFormat is used by the index.
> We would like to be able to configure a StoredFieldsFormat per field, similarly to the
PostingsFormat.
> There is a few issues that need to be solved for allowing that:
> 1) allowing to configure a segment suffix to the StoredFieldsFormat
> 2) implement SPI interface in StoredFieldsFormat 
> 3) create a PerFieldStoredFieldsFormat
> We are proposing to start first with 1) by modifying the signature of StoredFieldsFormat#fieldsReader
and StoredFieldsFormat#fieldsWriter so that they use SegmentReadState and SegmentWriteState
instead of the current set of parameters.
> Let us know what you think about this idea. If this is of interest, we can contribute
with a first path for 1).
