# OpenTSDBReader 插件文档
___
## 1 快速介绍
OpenTSDBReader 插件实现了从 OpenTSDB 读取数据。OpenTSDB 是主要由 Yahoo 维护的、可扩展的、分布式时序数据库，与阿里巴巴自研 TSDB 的关系与区别详见阿里云官网：《[相比 OpenTSDB 优势](https://help.aliyun.com/document_detail/113368.html)》
## 2 实现原理
在底层实现上，OpenTSDBReader 通过 HTTP 请求链接到 OpenTSDB 实例，利用 `/api/config` 接口获取到其底层存储 HBase 的连接信息，再利用 AsyncHBase 框架连接 HBase，通过 Scan 的方式将数据点扫描出来。整个同步的过程通过 metric 和时间段进行切分，即某个 metric 在某一个小时内的数据迁移，组合成一个迁移 Task。
## 3 功能说明
### 3.1 配置样例
* 配置一个从 OpenTSDB 数据库同步抽取数据到本地的作业：
```json
{
"job": {
"content": [
{
"reader": {
"name": "opentsdbreader",
"parameter": {
"endpoint": "http://localhost:4242",
"column": [
"m"
],
"beginDateTime": "2019-01-01 00:00:00",
"endDateTime": "2019-01-01 03:00:00"
}
},
"writer": {
"name": "streamwriter",
"parameter": {
"encoding": "UTF-8",
"print": true
}
}
}
],
"setting": {
"speed": {
"channel": 1
}
}
}
}
```
### 3.2 参数说明
* **name**
* 描述：本插件的名称
* 必选：是
* 默认值：opentsdbreader
* **parameter**
* **endpoint**
* 描述：OpenTSDB 的 HTTP 连接地址
* 必选：是
* 格式：http://IP:Port
* 默认值：无
* **column**
* 描述：数据迁移任务需要迁移的 Metric 列表
* 必选：是
* 默认值：无
* **beginDateTime**
* 描述：和 endDateTime 配合使用，用于指定哪个时间段内的数据点，需要被迁移
* 必选：是
* 格式：`yyyy-MM-dd HH:mm:ss`
* 默认值：无
* 注意：指定起止时间会自动忽略分钟和秒，转为整点时刻，例如 2019-4-18 的 [3:35, 4:55) 会被转为 [3:00, 4:00)
* **endDateTime**
* 描述：和 beginDateTime 配合使用，用于指定哪个时间段内的数据点，需要被迁移
* 必选：是
* 格式：`yyyy-MM-dd HH:mm:ss`
* 默认值：无
* 注意：指定起止时间会自动忽略分钟和秒，转为整点时刻，例如 2019-4-18 的 [3:35, 4:55) 会被转为 [3:00, 4:00)
### 3.3 类型转换
| DataX 内部类型 | TSDB 数据类型 |
| -------------- | ------------------------------------------------------------ |
| String | TSDB 数据点序列化字符串，包括 timestamp、metric、tags 和 value |
## 4 性能报告
### 4.1 环境准备
#### 4.1.1 数据特征
从 Metric、时间线、Value 和 采集周期 四个方面来描述：
##### metric
固定指定一个 metric 为 `m`。
##### tagkv
前四个 tagkv 全排列，形成 `10 * 20 * 100 * 100 = 2000000` 条时间线，最后 IP 对应 2000000 条时间线从 1 开始自增。
| **tag_k** | **tag_v** |
| --------- | ------------- |
| zone | z1~z10 |
| cluster | c1~c20 |
| group | g1~100 |
| app | a1~a100 |
| ip | ip1~ip2000000 |
##### value
度量值为 [1, 100] 区间内的随机值
##### interval
采集周期为 10 秒，持续摄入 3 小时，总数据量为 `3 * 60 * 60 / 10 * 2000000 = 2,160,000,000` 个数据点。
#### 4.1.2 机器参数
OpenTSDB Reader 机型: 64C256G
HBase 机型： 8C16G * 5
#### 4.1.3 DataX jvm 参数
"-Xms4096m -Xmx4096m"
### 4.2 测试报告
| 通道数| DataX 速度 (Rec/s) |DataX 流量 (MB/s)|
|--------| --------|--------|
|1| 215428 | 25.65 |
|2| 424994 | 50.60 |
|3| 603132 | 71.81 |
## 5 约束限制
### 5.1 需要确保与 OpenTSDB 底层存储的网络是连通的
具体缘由详见 6.1
### 5.2 如果存在某一个 Metric 下在一个小时范围内的数据量过大，可能需要通过 `-j` 参数调整 JVM 内存大小
考虑到下游 Writer 如果写入速度不及 OpenTSDB reader 的查询数据，可能会存在积压的情况，因此需要适当地调整 JVM 参数。以"从 OpenTSDB 数据库同步抽取数据到本地的作业"为例，启动命令如下：
```bash
python datax/bin/datax.py opentsdb2stream.json -j "-Xms4096m -Xmx4096m"
```
### 5.3 指定起止时间会自动被转为整点时刻
指定起止时间会自动被转为整点时刻，例如 2019-4-18 的 `[3:35, 3:55)` 会被转为 `[3:00, 4:00)`
### 5.4 目前只支持兼容 OpenTSDB 2.3.x
其他版本暂不保证兼容
## 6 FAQ
***
**Q：为什么需要连接 OpenTSDB 的底层存储，为什么不直接使用 `/api/query` 查询获取数据点？**
A：因为通过 OpenTSDB 的 HTTP 接口（`/api/query`）来读取数据的话，经内部压测发现，在大数据量的情况下，会导致 OpenTSDB 的异步框架会报 CallBack 过多的问题；所以，采用了直连底层 HBase 存储，通过 Scan 的方式来扫描数据点，来避免这个问题。另外，还考虑到，可以通过指定 metric 和时间范围，可以顺序地 Scan HBase 表，提高查询效率。

# TSDBWriter 插件文档
___
## 1 快速介绍
TSDBWriter 插件实现了将数据点写入到阿里巴巴自研 TSDB 数据库中（后续简称 TSDB）。
时间序列数据库（Time Series Database , 简称 TSDB）是一种高性能，低成本，稳定可靠的在线时序数据库服务；提供高效读写，高压缩比存储、时序数据插值及聚合计算，广泛应用于物联网（IoT）设备监控系统 ，企业能源管理系统（EMS），生产安全监控系统，电力检测系统等行业场景。 TSDB 提供百万级时序数据秒级写入，高压缩比低成本存储、预降采样、插值、多维聚合计算，查询结果可视化功能；解决由于设备采集点数量巨大，数据采集频率高，造成的存储成本高，写入和查询分析效率低的问题。更多关于 TSDB 的介绍，详见[阿里云 TSDB 官网](https://help.aliyun.com/product/54825.html)。
## 2 实现原理
通过 HTTP 连接 TSDB 实例，并通过 `/api/put` 接口将数据点写入。关于写入接口详见 TSDB 的[接口说明文档](https://help.aliyun.com/document_detail/59939.html)。
## 3 功能说明
### 3.1 配置样例
* 配置一个从 OpenTSDB 数据库同步抽取数据到 TSDB：
```json
{
"job": {
"content": [
{
"reader": {
"name": "opentsdbreader",
"parameter": {
"endpoint": "http://localhost:4242",
"column": [
"m"
],
"startTime": "2019-01-01 00:00:00",
"endTime": "2019-01-01 03:00:00"
}
},
"writer": {
"name": "tsdbhttpwriter",
"parameter": {
"endpoint": "http://localhost:8242"
}
}
}
],
"setting": {
"speed": {
"channel": 1
}
}
}
}
```
### 3.2 参数说明
* **name**
* 描述：本插件的名称
* 必选：是
* 默认值：tsdbhttpwriter
* **parameter**
* **endpoint**
* 描述：TSDB 的 HTTP 连接地址
* 必选：是
* 格式：http://IP:Port
* 默认值：无
* **batchSize**
* 描述：每次批量数据的条数
* 必选：否
* 格式：int，需要保证大于 0
* 默认值：100
* **maxRetryTime**
* 描述：失败后重试的次数
* 必选：否
* 格式：int，需要保证大于 1
* 默认值：3
* **ignoreWriteError**
* 描述：如果设置为 true，则忽略写入错误，继续写入；否则，多次重试后仍写入失败的话，则会终止写入任务
* 必选：否
* 格式：bool
* 默认值：false
### 3.3 类型转换
| DataX 内部类型 | TSDB 数据类型 |
| -------------- | ------------------------------------------------------------ |
| String | TSDB 数据点序列化字符串，包括 timestamp、metric、tags 和 value |
## 4 性能报告
### 4.1 环境准备
#### 4.1.1 数据特征
从 Metric、时间线、Value 和 采集周期 四个方面来描述：
##### metric
固定指定一个 metric 为 `m`。
##### tagkv
前四个 tagkv 全排列，形成 `10 * 20 * 100 * 100 = 2000000` 条时间线，最后 IP 对应 2000000 条时间线从 1 开始自增。
| **tag_k** | **tag_v** |
| --------- | ------------- |
| zone | z1~z10 |
| cluster | c1~c20 |
| group | g1~100 |
| app | a1~a100 |
| ip | ip1~ip2000000 |
##### value
度量值为 [1, 100] 区间内的随机值
##### interval
采集周期为 10 秒，持续摄入 3 小时，总数据量为 `3 * 60 * 60 / 10 * 2000000 = 2,160,000,000` 个数据点。
#### 4.1.2 机器参数
TSDB Writer 机型: 64C256G
HBase 机型： 8C16G * 5
#### 4.1.3 DataX jvm 参数
"-Xms4096m -Xmx4096m"
### 4.2 测试报告
| 通道数 | DataX 速度 (Rec/s) | DataX 流量 (MB/s) |
| ------ | ------------------ | ----------------- |
| 1 | 129753 | 15.45 |
| 2 | 284953 | 33.70 |
| 3 | 385868 | 45.71 |
## 5 约束限制
### 5.1 目前只支持兼容 TSDB 2.4.x 及以上版本
其他版本暂不保证兼容
