Re: [appengine-java] A catch-all servlet?

You could create a filter that is mapped to "/*" and does a forward to your jsp. This one remembers the original path: public class ForwardFilter implements Filter { public static final String SERVLET_PATH = ForwardFilter.class.getName() + ".servletPath"; private String target;

Re: [appengine-java] Re: JDO Relationship Performance Problems - what am I doing wrong?

The most important number in my mind is the number of line items in an order. If you're seeing 20s+ queries, it must be a pretty large number. Objectify (and Twig) support queryable collections of embedded objects, so you can put all the line items in a single order object. There are some practic

Re: [appengine-java] elegant way of implementing sequence generator

Memcache data is never persisted to disk, so in the event of a Memcache server restart, you will lose all the data in Memcache. In addition, Memcache evicts items based on an LRU cache: if you don't use data for a while and space is needed, the item will be removed from your cache to allow for your

"We get a list of Keys back and figure out keys." I just realized how confusing this is - we get a list of INDEX keys back. These don't have any value; we do all storage inside the Key. We extract the keys of the Entity from the returned Index keys and do a query. On Tue, Apr 6, 2010 at 11:42 AM,

Re: [appengine-java] Re: Database cursor for "back" cursor?

Offset doesn't fetch data - it does an index scan. Going to the 10,000th result using offset will require us to pass 10,000 results first in our index, but we won't be retrieving those objects. Here's a bit of a simplification of indexes, entities and how these queries work. As you know, Bigtable i

This seems redundant, even outside of App Engine. You wouldn't want to place a JSessionId into a cookie, since that is identified *by* a cookie. Likely what you are looking for is servlet session support. App Engine supports this, albeit with gotchas: http://code.google.com/appengine/docs/java/co

For speed, you'll get the most gains if you denormalize when possible - yes, the relational purists are going to riot, but you don't have many of the benefits of normalization anyway such as foreign key constraints or native joins. If that isn't an option - and I really do recommend looking into i
