# SQL MODE
+
Doris新支持的sql mode参照了 Mysql 的sql mode管理机制，每个客户端都能设置自己的sql mode，拥有Admin权限的数据库管理员可以设置全局sql mode。
-##sql mode 介绍
+## sql mode 介绍
+
sql mode使用户能在不同风格的sql语法和数据校验严格度间做切换，使Doris对其他数据库有更好的兼容性。例如在一些数据库里，'||'符号是一个字符串连接符，但在Doris里却是与'or'等价的，这时用户只需要使用sql mode切换到自己想要的风格。每个客户端都能设置sql mode，并在当前对话中有效，只有拥有Admin权限的用户可以设置全局sql mode。
-##原理
+## 原理
+
sql mode用一个64位的Long型存储在SessionVariables中，这个地址的每一位都代表一个mode的开启/禁用(1表示开启，0表示禁用)状态，只要知道每一种mode具体是在哪一位，我们就可以通过位运算方便快速的对sql mode进行校验和操作。
每一次对sql mode的查询，都会对此Long型进行一次解析，变成用户可读的字符串形式，同理，用户发送给服务器的sql mode字符串，会被解析成能够存储在SessionVariables中的Long型。
已被设置好的全局sql mode会被持久化，因此对全局sql mode的操作总是只需一次，即使程序重启后仍可以恢复上一次的全局sql mode。

# Backup and Recovery
Doris supports the backup of current data in the form of files to remote storage systems via broker. The data can then be restored from the remote storage system to any Doris cluster by the restore command. With this feature, Doris can support regular snapshot backups of data. It can also be used to migrate data between different clusters.

# Stream load
Stream load is a synchronous way of importing. Users import local files or data streams into Doris by sending HTTP protocol requests. Stream load synchronously executes the import and returns the import result. Users can directly determine whether the import is successful by the return body of the request.

+# SQL MODE
+
The SQL MODE supported by Doris refers to the sql mode management mechanism of MySQL. Each client can set its own sql mode, and the database administrator with admin permission can set the global sql mode.
-##Sql mode introduction
+## Sql mode introduction
+
SQL MODE enables users to switch between different styles of SQL syntax and data verification strictness, making Doris more compatible with other databases. For example, in some databases, the '||' symbol is a string connector, but in Doris it is equivalent to 'or'. At this time, users only need to use SQL mode to switch to the style they want. Each client can set sql mode, which is valid in the current conversation. Only users with admin permission can set global SQL mode.
-##Theory
+## Theory
+
SQL MODE is stored in session variables with a 64 bit long type. Each bit of this address represents the on / off (1 for on, 0 for off) state of a mode. As long as we know the specific bit of each mode, we can easily and quickly verify and operate SQL mode through bit operation.
Every time you query sql mode, the long type will be parsed into a user-readable string. Similarly, the sql mode string sent by the user to the server will be parsed into a long type that can be stored in session variables.
The set global sql mode will be persisted, so the operation on the global sql mode is always only once, even after the program is restarted, the last global sql mode can be recovered.

# Subscribe to mailing lists
Mail List is the most recognized form of communication in Apache community. Generally speaking, open source community questions and answers, technical discussions, transaction decisions are carried through mailing lists. The asynchronous and broadcasting features of mailing lists are also very suitable for communication in open source communities. So how do you subscribe to Apache Doris (incubating) mailing lists? It mainly includes the following five steps.
