[appengine-java] Re: JDO Query ordering issue
The restriction I am referring to is mentioned here: http://code.google.com/appengine/docs/java/datastore/jdo/queries.html Scroll down to Query Sort Orders where it says: Due to the way the App Engine datastore executes queries, if a query specifies inequality filters on a property and sort orders on other properties, the property used with the inequality filters must be ordered before the other properties.

[appengine-java] Re: JDO Query ordering issue
I was thinking of import com.google.appengine.api.datastore.Query; http://code.google.com/appengine/docs/java/datastore/queries.html I'm not sure that's going to help b/c of the restriction mentioned. The way I deal with it is use multiple query drill down and depending on size I'll send them into another tmp jdo class or into an array and keep drilling (querying) the data until I get what I want. I've found it doesn't add to much overhead. But I'm sure there are other ways too.

[appengine-java] Re: JDO Query ordering issue
I think this is referring to the indexes needed to perform the query and not the sort orders needed. All you need to do is order only on score. As long as your indexes are updated your query should work fine.

[appengine-java] Re: why the development of java tools fall far behind that of python's?
Tapir, thanks for your feedback. I agree that there have been several cases where features have come out in Python long before Java. (There have been a few in the other direction too, but not as many.) This is something we are trying to improve upon in the future. I'm happy to tell you that one of the items in your list, 1. remove obsolete indexes, is supported in Java and has been since release 1.4.2 earlier this year. This feature is called vacuum indexes. - Mitch On May 25, 9:00 am, Tapir tapir@gmail.com wrote: such as: 1. remove obsolete indexes 2. copy Mater-Slave data to High Replication I think if these tools are already done in python, it would be easy to port them in java within one week, especially for your googlers.

I would also point out that it is possible for Java apps to migrate from Master/Slave to High Replication: http://code.google.com/appengine/docs/adminconsole/datastoreadmin.html#Copying_Entities_to_Another_Application Having to create an empty Python version of your app is no doubt clunky and not something we're happy about having to recommend, but it doesn't take much effort and it does work.

Re: [appengine-java] Re: why the development of java tools fall far behind that of python's?
+1 The primary benefit of GAE comes from the services (datastore, task queue, memcache, etc) and the language is pretty much secondary. Don't be afraid to set up the Python SDK - it's *really* trivial (especially compared to setting up Eclipse). You don't even need to learn any Python. Chances are, the only think you'll find confusing is the structure of YAML, but it's not that big of a deal.
