Log at DEBUG will show the MongoDB "query" filter. Should be clear from that if 
all components of the JDOQL are in the datastore query. 

An example
JDOQL : SELECT FROM org.jpox.samples.models.company.Person WHERE firstName == 
'Daffy' && personNum < 3

Fetching instances of collection Person fields={ "age" : 1 , "birthDate" : 1 , 
"emailAddress" : 1 , "firstName" : 1 , "globalNum" : 1 , "lastName" : 1 , 
"personNum" : 1} with filter={ "firstName" : "Daffy" , "personNum" : { "$lt" : 
3}}

In this case the "filter" is complete, hence nothing to do in-memory. The 
"fields" part of that line are the fields retrieved (i.e DFG)

Hi Andy,

thanks for info and the link, this is really helpful.

One question about running JDOQL queries on of MongoDB: is there any 
chance to figure out whether a specific JDOQL query is pushed to MongoDB 
or evaluated in memory? Do I find any info about this is the DataNucleus 
log files (having the right log level)?


Regards Michael



Michael reports that he's using DataNucleus with MongoDB and it's
sweet that everything, including JDOQL seems to work fine!

Good to hear. Obviously the MongoDB support lacks some features (some of which
are due to the lack of capability in the datastore), and most JDOQL will be
evaluated in-memory (due to lack of in-datastore capability for many
operators/methods - simple things like arithmetic operators are in datastore),
but aimed to make it as seamless as possible.

See this for unsupported features with other datastores
http://www.datanucleus.org/products/accessplatform/datastore_features.html

Would be nice to one day run the TCK on them all and get pretty complete
coverage ;-)

Hi,


https://issues.apache.org/jira/browse/JDO-700 may be because there is 
a new package for a pc test class?


I looked at JDO-700. It has nothing to do with new pc test classes. It 
was an issue with path separators on Windows.

The fix is checked in into the trunk.

Regards Michael
