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

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.

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