Subject [jira] [Commented] (SOLR-2823) Re-use of UpdateProcessor configurations in multiple UpdateChains
Date Wed, 12 Oct 2011 07:11:11 GMT

    [ https://issues.apache.org/jira/browse/SOLR-2823?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13125641#comment-13125641
] 

Jan Høydahl commented on SOLR-2823:
-----------------------------------

Sub chains could solve the exact example, but that was just for showing the principle. I think
(optinally) named processors are a more direct solution. Think of the named processors as
processor configs, not necessarily 1:1 with Java objects. When instansiating the "crawl" chain
we'd simply fetch the config from the referenced element instead of inline. It may still have
a distinct "solr.LanguageIdentifierUpdateProcessorFactory" class instance from the "cms" pipeline.

Sub chains may also come in handy for some situations, but that could be handled separately
later, if needed.

> When dealing with multiple UpdateChains and Processors, you frequently need to re-use
configuration. Two chains may be equal except for one config setting in one <processor>.
> I propose to allow named processor configs, which can be referenced by name in the chains.
