 StoneDB is a MySQL-compatible high-performance hybrid transaction/analytical processing (HTAP) database. It provides analytical processing (AP) abilities to MySQL. The running systems can be seamlessly migrated to StoneDB without any code changed. Compared to InnoDB, StoneDB provides 10 times the query performance as well as 10 times the load performance. StoneDB also provides 10:1 to 40:1 compression ratio.

+
+## 配置 StoneDB
+
+StoneDB安装完成后，您至少需要在**my.cnf**文件中配置以下参数:
+
+```
+#the stonedb configuration options are listed as following.
+#for an example.
+[mysqld] 
+# 如果是5.7及以后的版本，引擎设置为tianmu
+default-storage-engine=tianmu
+# 如果是5.6版本，引擎要设置为stonedb
+# default-storage-engine=stonedb
+binlog-format=STATEMENT
+```
+
+## 初始化数据库
+
+```bash
+# 对于 5.6 版本
+cd /path/to/your/path/bin && ./mysql_install_db --basedir=/stonedb/install/ --datadir=/stonedb/install/data/ --user=mysql
+
+# 对于 5.7 及以后的版本
+cd /path/to/your/path/bin && ./mysqld --initialize --basedir=/stonedb/install/ --datadir=/stonedb/install/data/ --user=mysql
+```
+
+## 启动数据库实例
+
+```bash
+mysqld_safe --defaults-file=/path/to/my.cnf --user=mysql & 
+```
+
+## 用 StoneDB 创建表
+
+```sql
+--The example code for creating a table with 'stonedb' engine.
+CREATE TABLE `example_table` (
+  `id1` bigint(20) NOT NULL DEFAULT '0',
+  `id1_type` int(10) NOT NULL DEFAULT '0',
+  `id2` bigint(20) NOT NULL DEFAULT '0',
+  `id2_type` int(10) NOT NULL DEFAULT '0',
+  `data` varchar(255) NOT NULL DEFAULT '',
+  `time` bigint(20) NOT NULL DEFAULT '0',
+  `version` int(11) NOT NULL DEFAULT '0',
+) ENGINE=stonedb;
+
+```
+
+这个例子展示了 StoneDB 中的一些重要特性和限制。有关限制的更多信息，请参见 [StoneDB Limitations](https://stonedb.io/docs/about-stonedb/limits).

+
+## 在生产环境中从 MySQL 切换到 StoneDB
+
+如果您想在同一个实例中同时使用 InnoDB 和 Tianmu 来运行连接查询，在文件**my.cnf**中设置**stonedb_ini_allowmysqlquerypath**为**1**。
+
+目前还没有开发在存储引擎之间移动数据的在线迁移工具，但是您显然希望在不停机、不丢失数据或不准确结果的情况下进行迁移。为了实现这一点，您需要从使用 InnoDB 引擎的源 MySQL 服务器上逻辑地移动数据，并将其加载到 Tianmu 中进行分析处理。具体流程如下:
+
+1. 创建一个StoneDB实例和表。
+
+2. 将所有数据库和表模式从源复制到目标。
+
+3. 通过执行 `SELECT…INTO OUTFILE` 将每个表转储到一个文件。
+
+4. 将文件发送到目的地，并使用 `load DATA…INFILE` 加载它们。

+# 常规变更
+## 表结构变更
+StoneDB 只支持以下表结构变更和数据变更操作，其它没有说明的表示不支持。
+### 创建相似表
+1）创建一张引擎为 stonedb 、名为 t_name 的表；
+```sql
+CREATE TABLE t_name(
+  col1 INT NOT NULL AUTO_INCREMENT,
+  col2 VARCHAR(10) NOT NULL,
+  ......
+  PRIMARY KEY (`col1`)
+) engine=stonedb;
+```
+:::info
+StoneDB 5.6 的存储引擎名是 stonedb，5.7 的存储引擎名是 tianmu。
+:::
+2）创建一张与 t_name 结构相同的表 t_other，使用 create table like 语句：
+```sql
+create table t_other like t_name;
+```
+### 清空表数据
+使用 truncate table 语句可以实现保留表结构，仅清空表中的数据。
+```sql
+truncate table t_name;
+```
+### 删除表
+```sql
+drop table t_name;
+```
+### 添加字段
+使用 alter table  ... add column 语句实现向指定表中添加字段，新增加的字段默认置于最后一个字段。
+```sql
+alter table t_name add column c_name varchar(10);
+```
+### 删除字段
+使用 alter table  ... drop 语句实现删除表中指定字段。
+```sql
+alter table t_name drop c_name;
+```
+### 重命名表
+使用 alter table ... rename to 语句实现对指定表的重命名。
+```sql
+alter table t_name rename to t_name_new;
+```
+## 用户权限变更
+### 创建用户
+```sql
+create user 'u_name'@'hostname' identified by 'xxx';
+```
+### 给用户赋权
+```sql
+grant all on *.* to 'u_name'@'hostname';
+grant select on db_name.* to 'u_name'@'hostname';
+grant select(column_name) on db_name.t_name to 'u_name'@'hostname';
+```
+### 回收用户权限
+```sql
+revoke all privileges on *.* from 'u_name'@'hostname';
+revoke select on db_name.* from 'u_name'@'hostname';
+revoke select(column_name) on db_name.t_name from 'u_name'@'hostname';
+```
+### 删除用户
+```sql
+drop user 'u_name'@'hostname';
+```
