--------------------------------------
Summary: Mongo DAO layer can't handle wildcard deletes
Key: RYA-17
URL: https://issues.apache.org/jira/browse/RYA-17
Project: Rya
Issue Type: Bug
Components: dao
Affects Versions: 3.2.10
Reporter: Christian Rasmussen
When requesting a delete using wildcards for either Predicate, Object or
Context we fail with a null pointer exception.
[DEBUG] 2015-12-15 00:05:06,341 [repositories/rya] subj="<http://tempuri.org>"
[DEBUG] 2015-12-15 00:05:06,348 [repositories/rya]

For this example, the only thing I specified in my delete request is the
'subj="<http://tempuri.org>”’
Dumping out the RYAStatement content here:
RyaStatement{subject=RyaType{dataType=http://www.w3.org/2001/XMLSchema#anyURI,
data='http://tempuri.org'}, predicate=null, object=null, context=null,
qualifier=null, columnVisibility=null, value=null, timestamp=1450155906348}
This then fails in the SimpleMongoDBStorageStrategy.serialize() because we are
trying to concatenate a bunch of fields to create the id (type String)
String id = statement.getSubject().getData() + " " +
statement.getPredicate().getData() + " " +
statement.getObject().getData() + " " +
context;
As an aside. We do not allow subject wildcard. This appears to be deliberate
and due to performance issues. However that seems like a feature that should
support as well.
