远程API，Objectify和DevServer不喜欢交易？ [英] Remote API, Objectify and the DevServer don't like transactions?

问题描述

我使用objectify 4来写入HRD数据存储。在单元测试中运行正常，并在devserver或production中运行应用程序。

但是，当我尝试使用REMOTE API连接到devserver数据存储区时，代码启动XG事务。在与Remote API连接时，似乎认为HRD未启用。
这就是我连接的方式...

pre $ public c om public static void main（String [] args）{
RemoteApiOptions options = new RemoteApiOptions（）。server（localhost，8888）.credentials（foo，bar）;
//选项=选项。
RemoteApiInstaller安装程序=新的RemoteApiInstaller（）;
StoredUser storedUser = null;
尝试{
installer.install（options）;
ObjectifyInitializer.register（）;
storedUser = new StoredUserDao（）。loadStoredUser（< KEY>）;
log.info（found user：+ storedUser.getEmail（））;

// !!!错误!!!
new SomeOtherDao（）。doSomeDataManipulationInTransaction（）;

} catch（Throwable e）{
e.printStackTrace（）;
} finally {
ObjectifyFilter.complete（）;
installer.uninstall（）;




$ b当新的SomeOtherDao（）。doSomeDataManipulationInTransaction（）启动一个多个实体组上的事务我收到错误：

多个实体组中的事务只能在高级复制应用程序中使用

如何告诉远程api这是一个HRD环境？ '未应用的作业百分比'设置为0，并且使用远程API的事务失败，就好像devserver正在使用主/从而不是HRD一样运行。将'未应用的工作比例'提高到零以上解决了问题。

I am using objectify 4 to write to the HRD datastore. Everything works fine in unit tests and running the application in devserver or production.

But when I try connect using the REMOTE API to the devserver datastore, an error is thrown when the code starts a XG transaction. While connecting with the Remote API, it seems to think that HRD is not enabled. This is how I connect ...

public static void main(String[] args) {
    RemoteApiOptions options = new RemoteApiOptions().server("localhost", 8888).credentials("foo", "bar");
    //options = options.
    RemoteApiInstaller installer = new RemoteApiInstaller();
    StoredUser storedUser = null;
    try {
        installer.install(options);
        ObjectifyInitializer.register();
        storedUser = new StoredUserDao().loadStoredUser(<KEY>);
        log.info("found user : " + storedUser.getEmail());

        // !!! ERROR !!!
        new SomeOtherDao().doSomeDataManipulationInTransaction();

    } catch (Throwable e) {
        e.printStackTrace();
    } finally {
        ObjectifyFilter.complete();
        installer.uninstall();
    }
}

When new SomeOtherDao().doSomeDataManipulationInTransaction() starts a transactions on multiple entity groups I get the error thrown :

transactions on multiple entity groups only allowed in High Replication applications

How can I tell the remote api that this is a HRD environment ?

解决方案

I had 'unapplied job percentage' set to 0 and transactions using the remote api failed as if the devserver was running with Master/Slave and not HRD. Raising the 'unapplied job percentage' above zero fixed the problem.
