Subject Re: Minutes: JDO TCK Conference Call Friday, Oct 21, 9 am Pacific Time

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
