Commit cannot be completed since the group has already rebalanced and assigned the partitions to another member. This means that the time between subsequent calls to poll() was longer than the configured max.poll.interval.ms, which typically implies that the poll loop is spending too much time message processing. You can address this either by increasing the session timeout or by reducing the maximum size of batches returned in poll() with max.poll.records.问题

这个问题来自于Kafka消费者,意思是消费者在调用poll()方法时,处理消息的时间太长,导致消费者无法在规定的时间内完成一次poll()操作,从而被认为已经失去了连接。为了解决这个问题,你可以尝试增加会话超时时间或者减少一次poll()方法返回的最大批次记录数(max.poll.records)。这样可以让消费者有更多的时间来处理消息,并避免被认为已经失去连接。

解决ExecuteReader requires the command to have a transaction when the connection assigned to the comma...
这个错误通常是由于在执行ExecuteReader方法之前没有为SqlCommand对象分配事务引起的。解决这个错误,你需要将SqlCommand对象与SqlTransaction对象关联起来,然后再执行ExecuteReader方法。以下是一个示例代码:
```
using (SqlConnection connection = new SqlConnection(connectionString))
{
connection.Open();
// 创建事务
SqlTransaction transaction = connection.BeginTransaction();
try
{
using (SqlCommand command = connection.CreateCommand())
{
// 将SqlCommand对象与SqlTransaction对象关联起来
command.Transaction = transaction;
command.CommandText = "SELECT * FROM [Table]";
SqlDataReader reader = command.ExecuteReader();
// 处理查询结果
reader.Close();
}
// 提交事务
transaction.Commit();
}
catch (Exception ex)
{
// 回滚事务
transaction.Rollback();
throw ex;
}
}
```
在这个示例中,我们首先在SqlConnection对象上调用Open方法打开数据库连接。接下来,我们创建一个SqlTransaction对象,并将其与SqlConnection对象关联起来。然后,在创建SqlCommand对象之后,我们将其与SqlTransaction对象关联起来。最后,我们执行ExecuteReader方法来执行查询,并在处理完查询结果后关闭SqlDataReader对象。如果在处理查询结果时发生任何错误,我们将回滚事务。如果一切顺利,我们将提交事务。
Your local changes to the following files would be overwritten by mergePlease, commit your changes or stash them before you can merge.怎么解决
您遇到的问题是在尝试从远程分支合并代码时,出现了以下提示:"Your local changes to the following files would be overwritten by merge. Please, commit your changes or stash them before you can merge." 这个提示表示您的本地工作区有未提交的更改,并且这些更改与远程分支上的更改冲突。为了解决这个问题,您可以考虑以下几种方法:
方法一:丢弃无用文件(推荐):
如果您确定本地的更改是无用的,可以直接丢弃这些更改。您可以使用以下命令将所有未提交的更改丢弃:
```
git stash drop
```
这将清除所有未提交的更改并恢复到远程分支的状态。
方法二:备份本地更改并拉取远程分支:
1. 在您的项目名称上右键,选择"Git",然后选择"Repository"和"Stash Changes",填写信息并点击"Create Stash"来备份您的本地更改。
2. 再次右键点击项目名称,选择"Git",然后选择"Repository"和"Pull"来拉取远程分支的最新更改。
3. 再次右键点击项目名称,选择"Git",然后选择"Repository"和"Unstash Changes"来应用之前备份的本地更改。
这样做可以将您的本地更改暂存起来,然后拉取远程分支的更改,并将之前备份的本地更改应用回来。如果在应用本地更改时出现冲突,您可以根据情况进行合并。
方法三:应用之前的暂存更改:
如果您之前使用了`git stash`命令来暂存了一些更改,您可以在成功拉取并合并远程更改后,使用以下命令将之前暂存的更改应用回来:
```
git stash apply
```
这将应用之前暂存的更改到当前工作区。
希望以上方法能够帮助您解决问题。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
