Question

您好，我在一个区域中插入了一个新条目，并在同一个事务中查询了一个OQL（SELECT * FROM / some_region_name），并且我发现在OQL结果中没有返回新的插入条目。任何人都知道发生了什么事吗？

这是我的测试代码：

Transaction begin.
checking username[forrest] before added.
rUserEntity NOT found
checking username[forrest] after added.
**rUserEntity found**
Transaction end.
checking username[forrest] after transaction.
rUserEntity  found

我期待结果：

Transaction begin.
checking username[forrest] before added.
rUserEntity NOT found
checking username[forrest] after added.
**rUserEntity NOT found**
Transaction end.
checking username[forrest] after transaction.
rUserEntity  found

但不幸的是我得到了这个结果：

foreach ($_REQUEST as $value)
{

 $sql = "INSERT INTO beer (b_beer) VALUES ('$value');";

 if(mysqli_query($connection, $sql))
  {
  echo "Records added successfully.";
  } 

   else
   {
   echo "ERROR: Could not able to execute $sql. " . mysqli_error($connection);
   }
}

这是一个已知的限制。 From the docs：

Queries and indexes reflect the cache contents and ignore the changes  
 made by ongoing transactions. If you do a query from inside a transaction, 
the query does not reflect the changes made inside that transaction.

Geode / Gemfire OQL的返回数据在事务视图中不正确
