Re: [appengine-java] Possibility for race condition on datastore?
Thanks for the input. Transactions is exactly what I was looking for. I coding a small game where people can attack each other and decrease their hp. If players ended up quering for the players hp and different datastores contain different values, well that's not a good thing haha. I'm planning on using the memcache to store the players hp, but when the value is removed from the cache I got to get the newest value back into the memcache.

2. how to combine the results from all these classes and list the comments by date? I dont understanding this part. any sample code on this? you will need 3 queries. one query for each entity. each queries will need to be executed individualy. ie (puesdo code) pm.execute(select c.text from CommentA c where date=?) pm.execute(select c.text from CommentB c where date=?) pm.execute(select c.text from CommentC c where date=?) so your write may be fast but now your reads will be slow. u cant 'OR' the queries since they are different entities.

Re: [google-appengine] Re: HR Vs. Master-Slave Comparison. Is it worth extra cost?
As far as eventual consistency goes, our users that are on high replication have not seen any issues. We are migrating to HR datastore. I was skeptical about eventual consistency, but when finally we tried HR datastore, we couldn't get it. I know that it is there somewhere, but it is so unnoticeable. My only concern is will it be noticeable when more applications migrate, but it is small price to pay for great availability.

[google-appengine] High Replication and Blob storage price
Hi all, http://code.google.com/appengine/docs/billing.html In the doc it says HR cost is $0.45 G/month. Does it include the blob store storage? or the storage by blob store remains at $0.15? It's not clear on the doc and from the admin page I always see total storage that's datastore + blobstore. I can understand that HR mode charge more for data stored in bigtable, but blob store data is a different kind of storage right? Say an app has 1G of user data and 10G of images stored in blobstore. The images are served statically and can never be changed. In this case really don't see (and need) the benefit of HR in serving the images.

[google-appengine] Seeking example of bulk loader post_import_function to skip records
Bulk loader is doing what I want, except I'd like to skip certain records on import. Using post_import_function and returning None as described in the docs to skip records instead returns the message NoneType has no attribute has_key. Has anyone successfully used post_import_function to skip records? I seek a very simple, very explicit, and non-deprecated example of doing that. Anybody have one? -- You received this message because you are subscribed to the Google Groups Google App Engine group. To post to this group, send email to google-appengine@googlegroups.com.

If you schedule writes it is not a big deal. I have several apps (admittedly not yet ported to GAE) that I only update the data from time to time. Recipe Databases, little league stats. In those cases you just delay the write, no big deal.
