--------------------------------------
Summary: sliceHash for compositeIdRouter is not coherent with
routing
Key: SOLR-7247
URL: https://issues.apache.org/jira/browse/SOLR-7247
Project: Solr
Issue Type: Bug
Affects Versions: 4.10.3
Reporter: Paolo Cappuccini
in CompositeIdRouter the function sliceHash check routeField configured for
collection.
This make me to guess that intended behaviour is manage alternative field to
id field to hash documents.
But the signature of this method is very general ( can take id, doc or params)
and it is used in different ways from different functionality.
If i configure routeField i noticed that is broken the DeleteCommand (this pass
to sliceHash only "id" and "params" ) and SolrIndexSplitter ( this pass only
"id" )
It should be forbidden to specify RouteField to compositeIdRouter or implements
related functionality to make possible to hash documents based on RouteField.
in case of DeleteCommand command the workaround is to specify "_route_" param
in request but in case of Index Splitting is not possible any workaround.
In this case it should be passed entire document during splitting ("doc"
parameter") or build params with proper "_route_" field.
