I've used the following code, to limited success...
<code>
<%@ page import="com.google.appengine.api.datastore.DatastoreService"
%>
<%@ page
import="com.google.appengine.api.datastore.DatastoreServiceFactory" %>
<%@ page import="com.google.appengine.api.datastore.Entity" %>
<%@ page import="com.google.appengine.api.datastore.PreparedQuery" %>
<%@ page import="com.google.appengine.api.datastore.Query" %>
<%@ page import="java.lang.Iterable" %>
<%
DatastoreService datastore =
DatastoreServiceFactory.getDatastoreService();
PreparedQuery global = datastore.prepare(new Query("__Stat_Kind__"));
for( Entity globalStat : global.asIterable() )
{
Long totalBytes = (Long) globalStat.getProperty("bytes");
Long totalEntities = (Long) globalStat.getProperty("count");
String kindName = (String) globalStat.getProperty("kind_name");
%><%= "[" + kindName + "] has " + totalEntities + " entities and
takes up " + totalBytes + "bytes<br/>" %><%
} // end for
%>
</code>
This works to a point. It seems I only shows that I have one entry for
my POJO when I know I have thousands. Perhaps the statistics aren't
updated for extended periods as I've seen on other threads. Hope this
helps you get all your kinds in one pass...
