Subject [jira] [Updated] (SOLR-7097) Update other Document in DocTransformer
Date Wed, 11 Feb 2015 16:56:12 GMT

     [ https://issues.apache.org/jira/browse/SOLR-7097?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

yuanyun.cn updated SOLR-7097:
-----------------------------
    Description: 
Solr DocTransformer is good, but it only allows us to change current document: add or remove,
update fields.

It would be great if we can update other document(previous especially) , or better we can
delete doc(especially useful during test) or add doc in 

User case:
We can use flat group mode(group.main=true) to put parent and child close to each other(parent
first), then we can use DocTransformer to update parent document when access its child document.

Some thought about Implementation:
org.apache.solr.response.TextResponseWriter.writeDocuments(String, ResultContext, ReturnFields)
when cachMode=true, in the for loop, after transform, we can store the solrdoc in a list,
write these doc at the end.

cachMode = req.getParams().getBool("cachMode", false);
SolrDocument[] cachedDocs = new SolrDocument[sz];
for (int i = 0; i < sz; i++) {
 SolrDocument sdoc = toSolrDocument(doc);
 if (transformer != null) {
  transformer.transform(sdoc, id);
 }
 if(cachMode)
 {
    cachedDocs[i] = sdoc;
 }
 else{
    writeSolrDocument( null, sdoc, returnFields, i );
 }
  
}
if (transformer != null) {
 transformer.setContext(null);
}
if(cachMode) {
 for (int i = 0; i < sz; i++) {
  writeSolrDocument(null, cachedDocs[i], returnFields, i);
 }
}
writeEndDocumentList();
