Subject [jira] Created: (SOLR-1396) standardize the updateprocessorchain syntax
Date Mon, 31 Aug 2009 07:03:33 GMT
standardize the updateprocessorchain syntax
-------------------------------------------

                 Key: SOLR-1396
                 URL: https://issues.apache.org/jira/browse/SOLR-1396
             Project: Solr
          Issue Type: Improvement
            Reporter: Noble Paul
             Fix For: 1.4


updateprocessorChain follows a non-standard syntax in solr . Usually, all the components are
initialized as top level components and they are assembled and used using a NamedList syntax
.for example search components.

I propose to change it as follows

{code:xml}
 <updateRequestProcessorChain name="custom" class="solr.UpdateRequestProcessorChain">

  <arr name="chain">
      <str>custom</str>
      <str>runUpdate</str>
      <str>log</str>
  </arr>
</updateRequestProcessorChain>
<updateProcessor name="custom" class="solr.CustomUpdateRequestProcessorFactory" >
   <lst name="name">
     <str name="n1">x1</str>
     <str name="n2">x2</str>
   </lst>
</updateProcessor>                                    
<updateProcessor name="runUpdate" class="solr.RunUpdateProcessorFactory" />        
           
<updateProcessor name="log" class="solr.LogUpdateProcessorFactory" />   
{code}

The wiki documentation says this was supposed to be reviewed. If possible we should clean
it up in 1.4 itself. We can support the old syntax too
