[appengine-java] About memcache specs
Hi all i was wondering how many MB will appengine give an app in memcache capacity? i know that it depends and it cannot be determined i do not need exact figure but a rough approximation , as i am trying to reduce application load time by storing common data in memcache, so i would like to know how big it is in order to determine how much data i will store init ,otherwise some data will be instantly removed another question: it seems that memcache eviction policy is LRU so does a call to contains method count toward the USE of an entry or do i have to call a get in order to keep it from being evicted if i have a running application, which have some load, and have a finite set of entry (a constant number) how much does it take to evict an unused entry? i wanna know about your experience with memcache not just the official statment thanks Joe -- You received this message because you are subscribed to the Google Groups "Google App Engine for Java" group.

[appengine-java] maximum size of a datastore API call response
Hi all in the doc , section "Quotas and Limits" i found "maximum size of a datastore API call response"= 1 MB what does this mean? does it mean that the query result cannot exceed 1 MB , so what about the rest of the result, does the JDO layer take care of this and handle it transparently or what? do i have to calculate anything for my queries or repeat them or page them to cope with this limitation? How exactly this limitation affects my code? another question as of release 1.3.2 the 1000 limitation of query result were gone... so if i want to get the entities from 1500 to 1520 is using the traditional way (in JDO, using the query.range(begin,limit)) uses cursors or do i have to use the cursor api as described in the docs is the default way (without cursors) still get all the results and drop the first 1500 thanks in advance Joe -- You received this message because you are subscribed to the Google Groups "Google App Engine for Java" group.

[appengine-java] Eclipse GAE plugin problem with Datanucleus enrichment
Hello,
I am using the Google App Engine Eclipse plugin and get an error when
I save a Java class with a get(String) method.
The enhancer is throwing a NullPointerException. I have added the
transient annotation and don't know what else I can do to avoid this
issue. Can anyobody please give me some advice?
I am using datanucleus-jpa-1.1.5.jar
I also posted this to the datanucleus forum but there doesn't seem to
be too much activity there so I was hoping I would get some ideas here
as well. http://www.jpox.org/servlet/forum/viewthread_thread,5954#31824
Thank you very much.
The referenced code is below:
@Entity
public class TestEntity implements Serializable {
private String dummyProperty;
public String getDummyProperty() {
return dummyProperty;
}
public void setDummyProperty(String dummyProperty) {
this.dummyProperty = dummyProperty;
}
@Transient
public Object get(String key) {
return null;
}
}

[appengine-java] Error 500 - Loading data to memory during startup
Hi, I am working with my friend to build an app (hoogentia.appspot.com) which requires loading some learned model files to memory. I have a startup servlet that does this (loading model files to memory). Since it needs more mem, I run this app in dev mode with memory setting of -Xms1024m -Xmx2048m. I dont have any issues in development but when i deploy it to app engine and access my application, the startup servlet is invoked and it comes up with an Error 500. I am not getting any useful info from the logs. I am assuming the issue is with jvm settings for app engine in production. I looked at this thread ( http://groups.google.com/group/google-appengine-java/browse_thread/thread/031d8875b6c8f1a7) and modified appcfg.sh to "java -Xmx2000m -cp "$SDK_LIB/appengine-tools-api.jar" \ com.google.appengine.tools.admin.AppCfg $* " After doing an update, I still get the 500 Error. In dev mode, it takes like 80 seconds for the model to get loaded in memory.

Using 1.2.2 This is kind of weird... I was developing my application and then all of a sudden I get this error. Everything was working fine, then datanucleus says it can't find the Cow class.
