+
+## What is PolarDB-X ？
+PolarDB-X is a cloud native distributed SQL Database designed for high concurrency, massive storage, complex querying scenarios. It has a shared-nothing architecture in which computing is decoupled from storage. It supports horizontal scaling, distributed transactions and Hybrid Transactional and Analytical Processing (HTAP) workloads, and is characterized by enterprise-class, cloud native, high availability, highly compatiable with MySQL and its ecosystem.
+
+PolarDB-X was originally created to solve the database's scalability bottleneck of Alibaba Tmall's "Double Eleven" core transaction system, and has grown with AliCloud along the way, and is a mature and stable database system that has been verified by many customers' core business systems.
+
+
+The core features of PolarDB-X include:
+
+- Horizontal Scalability
+
+PolarDB-X is designed with Shared-nothing architecture, supporting multiple Hash and Range data sharding algorithms and achieving transparent horizontal scaling through implicit primary key sharding and dynamic scheduling of data shard.
+
+
+- Distributed Transactions
+
+PolarDB-X adopts MVCC + TSO approach and 2PC protocol to implement distributed transactions. Transactions meet ACID characteristics, support RC/RR isolation levels, and achieve high performance through optimizations such as one-stage commit, read-only transaction, and asynchronous commit.
+
+
+- HTAP
+
+PolarDB-X supports analytical queries through native MPP capability, and achieves strong isolation of OLTP and OLAP traffic through CPU quota constraint, memory pooling, storage resource separation, etc.
+
+
+- Enterprise-class
+
+PolarDB-X has many capabilities designed for enterprise scenarios, such as SQL Concurrency Control, SQL Advisor, TDE, Triple Authority Seperation, Flashback Query, etc.
+
+
+- Cloud Native
+
+PolarDB-X has years of cloud native practice on AliCloud, supports managing cluster resources via K8S Operator, supports public cloud, hybrid cloud, private cloud and other forms for deployment.
+
+
+- High Availability
+
+PolarDB-X achieves strong data consistency through Multi-Paxos protocol, supports cross-data center deployment, and improves system availability through Table Group, Geo-locality, etc.
+
+
+- Compatiable with MySQL and Its Ecosystem
+
+The goal of PolarDB-X is to be fully compatible with MySQL, which currently includes MySQL protocol, most of MySQL SQL syntax, Collations, transaction isolation level, binary log, etc.
+
+
+## Quick Start
+### To quick start with PolarDB-X
+PolarDB-X supports one-click installation by PXD tool, through which you can quickly try the functions of PolarDB-X.
+
+See the [PXD Quick Start](https://github.com/polardb/polardbx-sql/blob/main/docs/en/quickstart.md).
+
+### To quick start with PolarDB-X on Kubernetes
+PolarDB-X provides K8S deployment mode, through which you can customize the configuration of PolarDB-X cluster.
+
+See the [K8S Quick Start](https://github.com/polardb/polardbx-operator#quick-start).
+
+### To start developing PolarDB-X
+Try the following steps under a non-root user to build and run PolarDB-X from the source code.
+
+>NOTE: CentOS 7&8 and Ubuntu 18 and higher are currently supported.
+
+0. Prerequisites
+
+Make sure the following packages are installed (for most cases, they are installed already):
+```shell
+# For CentOS
+yum install -y sudo git make redhat-lsb-core
+# For Ubuntu
+apt-get update && apt-get install -y sudo git make lsb-release
+```
+
+Create and switch to a non-root user with sudo privilege.
+```shell
+useradd -ms /bin/bash polarx
+echo "polarx:polarx" | chpasswd
+echo "polarx    ALL=(ALL)    NOPASSWD: ALL" >> /etc/sudoers
+su - polarx
+git clone https://github.com/polardb/polardbx.git
+cd polardbx
+```
+
+1. Build
+
+```shell
+make
+```
+
+`make` will download all repositories, install build tools and libraries, build and install PolarDB-X.
+Repositories are downloaded to `./build` dir and binaries are installed to `./build/run`. 
+You can run `make clean` to remove the installation and try build PolarDB-X again. 
+You can also run `make cleanAll` to remove everything under `./build`.
+
+This process may take more than half an hour depending on your network bandwidth.
+
+2. Run
+
+```shell
+./build/run/bin/polardb-x.sh start
+```
+
+Wait about 1 minute and use `mysql -h127.0.0.1 -P8527 -upolardbx_root` to connect to PolarDB-X.
+
+3. Stop
+
+```shell
+./build/run/bin/polardb-x.sh stop
+```
+
+The core features of PolarDB-X community version will be consistent with the commercial version, and more manuals can be found in [the documentations of the commercial version](https://www.alibabacloud.com/help/doc-detail/71252.htm). The documentations of the community version are being compiled and will be released to the public in the near future.
+
+## Architecture
+![image.png](https://github.com/polardb/polardbx-sql/blob/main/docs/architecture.png)
+PolarDB-X has a shared-nothing architecture in which compute and storage is decoupled, and the system consists of 4 core components.
+
+- CN (Compute Node)
+
+The Compute Node is the entry point of the system and is stateless, which includes modules such as SQL parser, optimizer, and executor. It is responsible for distributed data routing, 2PC coordination, global secondary index maintenance, etc. It also provides enterprise features such as SQL concurrency control and triple authority separation.
+
+
+- DN (Data Node)
+
+The Data Node is responsible for data persistence, providing strong data consistency based on the Multi-Paxos protocol, while maintaining distributed transaction visibility through MVCC.
+
+
+- GMS (Global Meta Service)
+
+The Gloal Meta Service is responsible for maintaining globally consistent Table/Schema, Statistics and other system Meta information, maintaining security information such as accounts and permissions, and providing global timing services (i.e. TSO).
+
+
+- CDC (Change Data Capture)
+
+The CDC Node provides change data capture capability that is fully compatible with the MySQL binary log format and MySQL DUMP protocol, and master-slave replication capability that is compatible with the MySQL Replication protocol.
+
+
+PolarDB-X provides tool to manage the above components through K8S Operator, and the RPC between the CN and DN can be done through private protocol component. The corresponding repositories of these components are as follows.
+
+| **Component Name** | **Repository** |
+| --- | --- |
+| CN (Compute Node) | [polardbx-sql](https://github.com/polardb/polardbx-sql) |
+| GMS (Global Meta Service) | [polardbx-engine](https://github.com/polardb/polardbx-engine) |
+| DN (Data Node) | [polardbx-engine](https://github.com/polardb/polardbx-engine) |
+| CDC (Change Data Capture) | [polardbx-cdc](https://github.com/polardb/polardbx-cdc) |
+| RPC | [polardbx-glue](https://github.com/polardb/polardbx-glue) |
+| K8S Operator | [polardbx-operator](https://github.com/polardb/polardbx-operator) |

+# Windows下编译运行PolarDB-X
+
+## 安装WSL
+参考官方文档：https://docs.microsoft.com/en-us/windows/wsl/install
+
+## 安装CentOS 7
+微软商店里没有提供CentOS 7，可以在这里下载：https://github.com/mishamosher/CentOS-WSL/releases
+
+验证过的版本是：https://github.com/mishamosher/CentOS-WSL/releases/tag/7.9-2111
+
+解压后运行CentOS7.exe（右键以管理员身份运行）即可完成安装，再次运行CentOS7.exe即可打开一个终端。
+
+## 环境准备
+1. 安装wget： 
+```
+yum install wget -y
+```
+
+2. 使用阿里云的yum仓库：
+```
+cd /etc/yum.repos.d/ && \
+wget -O CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo && \
+yum clean all
+
+cd /root
+```
+
+3. 安装工具链
+```
+yum install -y git
+
+yum install -y centos-release-scl
+
+yum install -y mysql
+
+yum install -y java-1.8.0-openjdk-devel
+
+yum install -y make automake openssl-devel ncurses-devel bison libaio-devel
+
+yum install -y devtoolset-7-gcc devtoolset-7-gcc-c++ devtoolset-7-binutils
+
+echo "source /opt/rh/devtoolset-7/enable" >>/etc/profile && source /etc/profile
+```
+
+4. 安装cmake：
+
+仓库里没有cmake3，需要从源码编译安装
+
+```
+wget https://cmake.org/files/v3.23/cmake-3.23.2.tar.gz && tar -zxvf cmake-3.23.2.tar.gz && cd cmake-3.23.2/
+./bootstrap && gmake && gmake install 
+```
+
+5. 创建admin用户：
+
+CN与DN都不允许以root用户启动，需要创建一个用户。
+```
+useradd -ms /bin/bash admin && \
+echo "admin:admin" | chpasswd && \
+echo "admin    ALL=(ALL)    NOPASSWD: ALL" >> /etc/sudoers &&   \
+su admin
+
+cd /home/admin
+```
+
+6. 安装maven：
+
+仓库中的maven版本太老了，装一个最新版本。
+```
+wget https://dlcdn.apache.org/maven/maven-3/3.8.6/binaries/apache-maven-3.8.6-bin.tar.gz && tar -zxvf apache-maven-3.8.6-bin.tar.gz
+
+echo 'PATH=/home/admin/apache-maven-3.8.6/bin:$PATH' >> /home/admin/.bashrc && \
+    echo "export PATH" >> /home/admin/.bashrc && \
+	source  /home/admin/.bashrc
+```
+
+国内使用阿里云的maven仓库比较快，https://developer.aliyun.com/mvn/guide
+
+修改maven的配置文件：
+```
+vi /home/admin/apache-maven-3.8.6/conf/settings.xml
+```
+在`<mirrors></mirrors>`标签中添加 mirror 子节点：
+```
+<mirror>
+  <id>aliyunmaven</id>
+  <mirrorOf>*</mirrorOf>
+  <name>阿里云公共仓库</name>
+  <url>https://maven.aliyun.com/repository/public</url>
+</mirror>
+```
+
+## 编译PolarDB-X
+
+1. 下载编译工程
+```
+git clone https://github.com/ApsaraDB/PolarDB-X.git
+
+cd PolarDB-X
+```
+
+2. 编译
+```
+make
+```
+
+注意：如果机器内存<=16G，请修改PolarDB-X/Makefile中编译的并行度，否则容易出现OOM，将 `CPU_CORES` 修改为 2
+

+
+
+3. 运行
+```
+./build/run/bin/polardb-x.sh start
+```
+
+4. 停止
+```
+./build/run/bin/polardb-x.sh stop
+```
+
+
+## 使用IDEA开发GalaxySQL（CN）
+
+我们使用IDEA来运行CN的代码，并使用CentOS中启动的GalaxyEngine节点作为GMS与DN节点。
+
+1. WSL与Windows是同一个LAN内的两个IP，在上述的Demo中，GMS中记录的DN的IP为`127.0.0.1`，Windows无法直接通过这个IP来访问与GMS/DN，因此需要获取到WSL的LAN IP，并做相应的替换。
+
+在CentOS中执行`ip addr`，记录eth0中的IP，如本例中，IP为`172.27.47.106`
+
+```
+ip addr
+
+1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000
+    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
+    inet 127.0.0.1/8 scope host lo
+       valid_lft forever preferred_lft forever
+    inet6 ::1/128 scope host
+       valid_lft forever preferred_lft forever
+2: bond0: <BROADCAST,MULTICAST,MASTER> mtu 1500 qdisc noop state DOWN group default qlen 1000
+    link/ether 7a:44:78:58:e8:32 brd ff:ff:ff:ff:ff:ff
+3: dummy0: <BROADCAST,NOARP> mtu 1500 qdisc noop state DOWN group default qlen 1000
+    link/ether 7a:e5:bd:1e:a3:ba brd ff:ff:ff:ff:ff:ff
+4: tunl0@NONE: <NOARP> mtu 1480 qdisc noop state DOWN group default qlen 1000
+    link/ipip 0.0.0.0 brd 0.0.0.0
+5: sit0@NONE: <NOARP> mtu 1480 qdisc noop state DOWN group default qlen 1000
+    link/sit 0.0.0.0 brd 0.0.0.0
+6: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP group default qlen 1000
+    link/ether 00:15:5d:05:db:9b brd ff:ff:ff:ff:ff:ff
+    inet 172.27.47.106/20 brd 172.27.47.255 scope global eth0
+       valid_lft forever preferred_lft forever
+    inet6 fe80::215:5dff:fe05:db9b/64 scope link
+       valid_lft forever preferred_lft forever
+```
+
+2. 在CentOS上登录GMS，并修改DN的IP。
+
+```
+ mysql -h127.1 -P4886 -uroot polardbx_meta_db_polardbx -e 'update storage_info set ip="172.27.47.106";'
+```
+
+3. Kill掉CentOS中的CN进程，避免冲突：
+
+```
+[admin@DESKTOP-UGTN860 PolarDB-X]$ jps
+13174 Jps
+15625 DaemonBootStrap
+16105 DumperBootStrap
+16139 TaskBootStrap
+17334 TddlLauncher
+[admin@DESKTOP-UGTN860 PolarDB-X]$ kill -9 17334
+```
+4. 在Windows中clone代码：
+
+```
+git clone https://github.com/ApsaraDB/galaxysql.git
+
+cd galaxysql
+
+git submodule update --init
+```
+
+5. 在IDEA中打开该maven工程，并修改IDEA的maven仓库为阿里云的maven仓库：
+
+![image](https://user-images.githubusercontent.com/2645985/173986060-a0cdba7e-04b6-46bf-a76c-66582c83d630.png)
+
+6. 调整IDEA编译的内存上限：
+
+![image](https://user-images.githubusercontent.com/2645985/173986190-f647d8d7-4188-4f29-854c-a906f0686ca2.png)
+
+7. 使用CentOS中的`PolarDB-X/build/run/galaxysql/conf/server.properties`内容覆盖IDEA中CN的`galaxysql\polardbx-server\src\main\resources`，并将`metaDbAddr`中的`127.0.0.1`修改为WSL的IP：
+
+![image](https://user-images.githubusercontent.com/2645985/173987557-9b2f72aa-25a9-4149-b1c9-8a05cd26c19d.png)
+
+同时，修改代码中 polardbx-server/src/main/resources/server.properties 文件:
+
+a. 将`metaDbAddr` 改为 `127.0.0.1:4886`
+
+b. 将`metaDbXprotoPort` 改为 `34886`
+
+c. 将`galaxyXProtocol` 改为 `2`
+
+d. 在shell中执行这行命令以获取`metaDbPasswd`：`mysql -h127.1 -P4886 -uroot -padmin -D polardbx_meta_db_polardbx -e "select passwd_enc from storage_info where inst_kind=2"`
+
+e. 增加`metaDbPasswd=<查询到的密码>` 。
+
+8. 运行一次`com.alibaba.polardbx.server.TddlLauncher`，此时会启动失败
+
+9. 修改`TddlLauncher`的`Run/Debug Configurations`，添加`dnPasswordKey=asdf1234ghjk5678
+`到环境变量中：
+
+
+![image](https://user-images.githubusercontent.com/2645985/173987036-5aa9560f-c1b7-4451-b164-82c457b0b597.png)
+![image](https://user-images.githubusercontent.com/2645985/173987081-4767f56b-20ce-43a7-9cff-f35fa01ab5ca.png)
+![image](https://user-images.githubusercontent.com/2645985/173987109-7ca46936-7f87-4c16-a0fe-73c7d5ab9bde.png)
+
+10. 再次运行`com.alibaba.polardbx.server.TddlLauncher`即可
+
+11. mysql终端可以连上本地的CN了
+
+```
+mysql -h 127.0.0.1 -upolardbx_root -p123456 -P8527
+```
+
+## 固定WSL的IP地址
+
+注意，WSL2每次重启都会重新分配一个IP，这会导致GMS与`server.properties`中记录的IP失效。有一个折中的方法，执行以下命令，会分别为WSL2与Windows分配一个指定的IP地址：
+
+```
+wsl -d CentOS7 -u root ip addr add 192.168.50.2/24 broadcast 192.168.50.255 dev eth0 label eth0:1
+netsh interface ip add address “vEthernet (WSL)” 192.168.50.1 255.255.255.0
+```
+
+这样可以将GMS与`server.properties`中的IP固定为`192.168.50.2`即可。
+
+确保每次重启WSL后运行该命令。

+## 简介
+PolarDB-X 是一款分布式数据库系统，其核心组件由 CN、DN、GMS 和 CDC 四个部分组成，实际运行中，每个组件是一个单独的进程。
+
+本文围绕 3 个场景介绍 PolarDB-X 的镜像使用方式。
+
+## 1. 基于docker 快速体验 PolarDB-X
+
+基于 PolarDB-X Docker 镜像，可快速在本地运行一个 PolarDB-X 实例并开始体验。
+首先将镜像下载到本地：
+
+```shell
+docker pull polardbx/polardb-x
+```
+
+之后运行如下命令启动一个 PolarDB-X 容器，建议docker内存>=12GB (CN/DN/CDC各自分配mem_size=4096)：
+
+```shell
+docker run -d --name polardb-x -m 12GB -p 3306:8527 -v /etc/localtime:/etc/localtime polardbx/polardb-x
+```
+
+等待之后即可通过 MySQL Client 连接到 PolarDB-X ：
+
+```shell
+mysql -h127.0.0.1 -upolardbx_root -p123456
+```
+
+PolarDB-X 高度兼容 MySQL 语法，与分布式相关的特性会对 SQL 语法进行扩展，可通过以下 SQL 指令初步体验 PolarDB-X:
+
+```mysql
+# 检查GMS 
+select * from information_schema.schemata;
+
+# 创建分区表
+create database polarx_example mode='auto';
+
+use polarx_example;
+
+create table example (
+  `id` bigint(11) auto_increment NOT NULL,
+  `name` varchar(255) DEFAULT NULL,
+  `score` bigint(11) DEFAULT NULL,
+  primary key (`id`)
+) engine=InnoDB default charset=utf8 
+partition by hash(id) 
+partitions 8;
+
+insert into example values(null,'lily',375),(null,'lisa',400),(null,'ljh',500);
+
+select * from example;
+
+show topology from example;
+
+# 检查CDC
+show master status;
+show binlog events in 'binlog.000001' from 4;
+
+
+# 检查DN和CN
+show storage;  
+show mpp;
+```
+
+以上过程在本地运行了一个 PolarDB-X 容器，容器中运行了1个CN进程，1个DN进程（该进程同时扮演GMS角色）和一个CDC进程，并且使用默认参数进行了系统初始化，初始化完成后通过8527端口对外提供服务。
+
+## 场景2. 手工调整 docker 内组件配置
+
+您可以通过传递环境变量 `mem_size` 来控制 CN 和 CDC 的内存占用，CN 和 CDC 会***分别***占用不超过 `mem_size(MB)` 的内存。
+同时，DN 的 buffer pool size 将设置为 `0.3*mem_size` 。此外，DN 的 my.cnf 文件以及数据文件位于容器内 `/home/polarx/polardbx/build/run/polardbx-engine/data` 这个目录下。
+您可以将该目录挂载到本地，然后暂停 (stop) 容器，修改 mycnf，再启动 (start) 容器。接下来，我们用一个例子说明这些配置项：
+
+1. 首先运行 polardb-x 容器，传递 mem_size 环境变量，并将数据目录挂载到本地：
+```shell
+docker run -d --name polardb-x -p 3306:8527 --env mem_size=8192 -v /etc/localtime:/etc/localtime -v polardbx-data:/home/polarx/polardbx/build/run/polardbx-engine/data polardbx/polardb-x
+```
+上述指令，使得 CN 、DN、 CDC 分别占用不超过 8GB 内存，即一共占用不超过 24GB 内存。
+同时，DN 的 `innodb_buffer_pool_size` 将设置为 `0.3*8192 MB`，最终取整为 2560MB。
+
+2. 如果要修改 my.cnf，待容器启动后，先暂停容器的运行
+```shell
+docker stop polardb-x 
+```
+
+3. 找到本地挂载的目录
+```shell
+docker volume inspect polardbx-data
+```
+通过上述指令找到 `Mountpoint`，进入该目录，修改其中的 `my.cnf` 然后保存
+
+4. 最后再重新启动容器
+```shell
+docker start polardb-x 
+```
+
+## 场景3. 基于 polardbx-sql 进行开发
+
+polardbx-engine（即 DN ） 是 MySQL 8.x 的一个分支，可参考 MySQL 官方文档进行相关开发工作。
+
+本文主要讲解如何用 IntelliJ IDEA + PolarDB-X Docker 镜像搭建 polardbx-sql（即 CN） 开发环境。
+
+### 启动 DN&GMS 容器
+CN 的运行依赖DN和GMS，GMS可以看做一个扮演特殊角色的DN，所以在进行CN开发时，可用一个容器同时扮演DN和GMS的角色。运行这样一个容器的命令如下：
+
+```shell
+docker run -d --name polardb-x --env mode=dev -p 4886:4886 -p 34886:34886 -v /etc/localtime:/etc/localtime -v polardb-x-data:/home/polarx/polardbx/build/run/polardbx-engine/data polardbx/polardb-x
+```
+
+该命令会启动一个名叫 polardb-x 的容器，通过环境变量 `mode` 设置容器运行模式为开发模式（即 `mode=dev`）并将 MySQL 协议端口和私有协议端口暴露出来以供 CN 使用。
+数据卷映射可以将数据保存下来，以便后续使用。
+`mode` 所有取值见最后一个小节。
+
+之后开始配置 CN 相关的内容。
+
+### 配置 server.properties
+首先修改代码中 polardbx-server/src/main/resources/server.properties 文件:
+
+1. 将`serverPort`改为 `8527`
+2. 将`metaDbAddr` 改为 `127.0.0.1:4886`
+3. 将`metaDbXprotoPort` 改为 `34886`
+4. 将`galaxyXProtocol` 改为 `2`
+5. 执行以下命令以获取`metaDbPasswd`：`docker exec polardb-x bash -c 'mysql -h127.1 -P4886 -uroot -D polardbx_meta_db_polardbx -e "select passwd_enc from storage_info where inst_kind=2"'` 
+6. 增加`metaDbPasswd=<查询到的密码>` 。
+
+然后开始配置 IntelliJ IDEA 相关参数。
+
+### 配置 IntelliJ IDEA
+设置环境变量（Environment Variables） `dnPasswordKey=asdf1234ghjk5678`
+由于 CN 编译过程比较耗内存，所以需要同时设置以下两个编译参数:
+
+6. Preference-Compiler-Build process heap size 设置为 4096.
+7. Preference-Build, Execution, -Build tools - maven - importing - VM options for importer 设置为 -Xmx2048m -Xms2048m.
+
+至此 CN 的运行环境便配置好了，之后可以启动 `TddlLauncher` 进行相关开发和调试。
+
+### 远程部署 DN，本地开发 CN
+当然，上述过程也可以在远程机器上部署 docker 容器来运行 polardbx-engine，
+对外开放相应端口（4886，34886），然后：
+1. 修改本地的 resources/server.properties 文件中的相应 ip，
+把 127.0.0.1 改成远程机器 ip。
+2. 登录远程机器，执行 `docker exec -it polardb-x bash` 登进 DN 容器。
+3. 修改 storage_info 的 ip 为远程机器 ip：`mysql -h127.1 -P4886 -uroot -Dpolardbx_meta_db_polardbx -e "update storage_info set ip='<远程机器 ip>'"`。
+4. 本地启动 `TddlLauncher` 即可。
