# CassandraReader 插件文档
___
## 1 快速介绍
CassandraReader插件实现了从Cassandra读取数据。在底层实现上，CassandraReader通过datastax的java driver连接Cassandra实例，并执行相应的cql语句将数据从cassandra中SELECT出来。
## 2 实现原理
简而言之，CassandraReader通过java driver连接到Cassandra实例，并根据用户配置的信息生成查询SELECT CQL语句，然后发送到Cassandra，并将该CQL执行返回结果使用DataX自定义的数据类型拼装为抽象的数据集，并传递给下游Writer处理。
对于用户配置Table、Column的信息，CassandraReader将其拼接为CQL语句发送到Cassandra。
## 3 功能说明
### 3.1 配置样例
* 配置一个从Cassandra同步抽取数据到本地的作业:
```
{
"job": {
"setting": {
"speed": {
"channel": 3
}
},
"content": [
{
"reader": {
"name": "cassandrareader",
"parameter": {
"host": "localhost",
"port": 9042,
"useSSL": false,
"keyspace": "test",
"table": "datax_src",
"column": [
"textCol",
"blobCol",
"writetime(blobCol)",
"boolCol",
"smallintCol",
"tinyintCol",
"intCol",
"bigintCol",
"varintCol",
"floatCol",
"doubleCol",
"decimalCol",
"dateCol",
"timeCol",
"timeStampCol",
"uuidCol",
"inetCol",
"durationCol",
"listCol",
"mapCol",
"setCol"
"tupleCol"
"udtCol",
]
}
},
"writer": {
"name": "streamwriter",
"parameter": {
"print":true
}
}
}
]
}
}
```
### 3.2 参数说明
* **host**
* 描述：Cassandra连接点的域名或ip，多个node之间用逗号分隔。 <br />
* 必选：是 <br />
* 默认值：无 <br />
* **port**
* 描述：Cassandra端口。 <br />
* 必选：是 <br />
* 默认值：9042 <br />
* **username**
* 描述：数据源的用户名 <br />
* 必选：否 <br />
* 默认值：无 <br />
* **password**
* 描述：数据源指定用户名的密码 <br />
* 必选：否 <br />
* 默认值：无 <br />
* **useSSL**
* 描述：是否使用SSL连接。<br />
* 必选：否 <br />
* 默认值：false <br />
* **keyspace**
* 描述：需要同步的表所在的keyspace。<br />
* 必选：是 <br />
* 默认值：无 <br />
* **table**
* 描述：所选取的需要同步的表。<br />
* 必选：是 <br />
* 默认值：无 <br />
* **column**
* 描述：所配置的表中需要同步的列集合。<br />
其中的元素可以指定列的名称或writetime(column_name)，后一种形式会读取column_name列的时间戳而不是数据。
* 必选：是 <br />
* 默认值：无 <br />
* **where**
* 描述：数据筛选条件的cql表达式，例如:<br />
```
"where":"textcol='a'"
```
* 必选：否 <br />
* 默认值：无 <br />
* **allowFiltering**
* 描述：是否在服务端过滤数据。参考cassandra文档中ALLOW FILTERING关键字的相关描述。<br />
* 必选：否 <br />
* 默认值：无 <br />
* **consistancyLevel**
* 描述：数据一致性级别。可选ONE|QUORUM|LOCAL_QUORUM|EACH_QUORUM|ALL|ANY|TWO|THREE|LOCAL_ONE<br />
* 必选：否 <br />
* 默认值：LOCAL_QUORUM <br />
### 3.3 类型转换
目前CassandraReader支持除counter和Custom类型之外的所有类型。
下面列出CassandraReader针对Cassandra类型转换列表:
| DataX 内部类型| Cassandra 数据类型 |
| -------- | ----- |
| Long |int, tinyint, smallint,varint,bigint,time|
| Double |float, double, decimal|
| String |ascii,varchar, text,uuid,timeuuid,duration,list,map,set,tuple,udt,inet |
| Date |date, timestamp |
| Boolean |bool |
| Bytes |blob |
请注意:
* 目前不支持counter类型和custom类型。

# CassandraWriter 插件文档
___
## 1 快速介绍
CassandraWriter插件实现了向Cassandra写入数据。在底层实现上，CassandraWriter通过datastax的java driver连接Cassandra实例，并执行相应的cql语句将数据写入cassandra中。
## 2 实现原理
简而言之，CassandraWriter通过java driver连接到Cassandra实例，并根据用户配置的信息生成INSERT CQL语句，然后发送到Cassandra。
对于用户配置Table、Column的信息，CassandraReader将其拼接为CQL语句发送到Cassandra。
## 3 功能说明
### 3.1 配置样例
* 配置一个从内存产生到Cassandra导入的作业:
```
{
"job": {
"setting": {
"speed": {
"channel": 5
}
},
"content": [
{
"reader": {
"name": "streamreader",
"parameter": {
"column": [
{"value":"name","type": "string"},
{"value":"false","type":"bool"},
{"value":"1988-08-08 08:08:08","type":"date"},
{"value":"addr","type":"bytes"},
{"value":1.234,"type":"double"},
{"value":12345678,"type":"long"},
{"value":2.345,"type":"double"},
{"value":3456789,"type":"long"},
{"value":"4a0ef8c0-4d97-11d0-db82-ebecdb03ffa5","type":"string"},
{"value":"value","type":"bytes"},
{"value":"-838383838,37377373,-383883838,27272772,393993939,-38383883,83883838,-1350403181,817650816,1630642337,251398784,-622020148","type":"string"},
],
"sliceRecordCount": 10000000
}
},
"writer": {
"name": "cassandrawriter",
"parameter": {
"host": "localhost",
"port": 9042,
"useSSL": false,
"keyspace": "stresscql",
"table": "dst",
"batchSize":10,
"column": [
"name",
"choice",
"date",
"address",
"dbl",
"lval",
"fval",
"ival",
"uid",
"value",
"listval"
]
}
}
}
]
}
}
```
### 3.2 参数说明
* **host**
* 描述：Cassandra连接点的域名或ip，多个node之间用逗号分隔。 <br />
* 必选：是 <br />
* 默认值：无 <br />
* **port**
* 描述：Cassandra端口。 <br />
* 必选：是 <br />
* 默认值：9042 <br />
* **username**
* 描述：数据源的用户名 <br />
* 必选：否 <br />
* 默认值：无 <br />
* **password**
* 描述：数据源指定用户名的密码 <br />
* 必选：否 <br />
* 默认值：无 <br />
* **useSSL**
* 描述：是否使用SSL连接。<br />
* 必选：否 <br />
* 默认值：false <br />
* **connectionsPerHost**
* 描述：客户端连接池配置：与服务器每个节点建多少个连接。<br />
* 必选：否 <br />
* 默认值：8 <br />
* **maxPendingPerConnection**
* 描述：客户端连接池配置：每个连接最大请求数。<br />
* 必选：否 <br />
* 默认值：128 <br />
* **keyspace**
* 描述：需要同步的表所在的keyspace。<br />
* 必选：是 <br />
* 默认值：无 <br />
* **table**
* 描述：所选取的需要同步的表。<br />
* 必选：是 <br />
* 默认值：无 <br />
* **column**
* 描述：所配置的表中需要同步的列集合。<br />
内容可以是列的名称或"writetime()"。如果将列名配置为writetime()，会将这一列的内容作为时间戳。
* 必选：是 <br />
* 默认值：无 <br />
* **consistancyLevel**
* 描述：数据一致性级别。可选ONE|QUORUM|LOCAL_QUORUM|EACH_QUORUM|ALL|ANY|TWO|THREE|LOCAL_ONE<br />
* 必选：否 <br />
* 默认值：LOCAL_QUORUM <br />
* **batchSize**
* 描述：一次批量提交(UNLOGGED BATCH)的记录数大小（条数）。注意batch的大小有如下限制：<br />
（1）不能超过65535。<br />
(2) batch中的内容大小受到服务器端batch_size_fail_threshold_in_kb的限制。<br />
(3) 如果batch中的内容超过了batch_size_warn_threshold_in_kb的限制，会打出warn日志，但并不影响写入，忽略即可。<br />
如果批量提交失败，会把这个批量的所有内容重新逐条写入一遍。
* 必选：否 <br />
* 默认值：1 <br />
### 3.3 类型转换
目前CassandraReader支持除counter和Custom类型之外的所有类型。
下面列出CassandraReader针对Cassandra类型转换列表:
| DataX 内部类型| Cassandra 数据类型 |
| -------- | ----- |
| Long |int, tinyint, smallint,varint,bigint,time|
| Double |float, double, decimal|
| String |ascii,varchar, text,uuid,timeuuid,duration,list,map,set,tuple,udt,inet |
| Date |date, timestamp |
| Boolean |bool |
| Bytes |blob |
请注意:
* 目前不支持counter类型和custom类型。

# TSDBReader 插件文档
___
## 1 快速介绍
TSDBReader 插件实现了从阿里云 TSDB 读取数据。阿里云时间序列数据库 ( **T**ime **S**eries **D**ata**b**ase , 简称 TSDB) 是一种集时序数据高效读写，压缩存储，实时计算能力为一体的数据库服务，可广泛应用于物联网和互联网领域，实现对设备及业务服务的实时监控，实时预测告警。详见 TSDB 的阿里云[官网](https://cn.aliyun.com/product/hitsdb)。
## 2 实现原理
在底层实现上，TSDBReader 通过 HTTP 请求链接到 阿里云 TSDB 实例，利用 `/api/query` 或者 `/api/mquery` 接口将数据点扫描出来（更多细节详见：[时序数据库 TSDB - HTTP API 概览](https://help.aliyun.com/document_detail/63557.html)）。而整个同步的过程，是通过时间线和查询时间线范围进行切分。
## 3 功能说明
### 3.1 配置样例
* 配置一个从 阿里云 TSDB 数据库同步抽取数据到本地的作业，并以**时序数据**的格式输出：
时序数据样例：
```json

### 3.2 参数说明
* **name**
* 描述：本插件的名称
* 必选：是
* 默认值：tsdbreader
* **parameter**
* **sinkDbType**
* 描述：目标数据库的类型
* 必选：否
* 默认值：TSDB

* **endpoint**
* 描述：阿里云 TSDB 的 HTTP 连接地址
* 必选：是
* 格式：http://IP:Port
* 默认值：无
* **column**
* 描述：TSDB 场景下：数据迁移任务需要迁移的 Metric 列表；RDB 场景下：映射到关系型数据库中的表字段，且增加 `__metric__`、`__ts__` 和 `__value__` 三个字段，其中 `__metric__` 用于映射度量字段，`__ts__` 用于映射 timestamp 字段，而 `__value__` 仅适用于单值场景，用于映射度量值，多值场景下，直接指定 field 字段即可
* 必选：是
* 默认值：无
* **metric**
* 描述：仅适用于 RDB 场景下，表示数据迁移任务需要迁移的 Metric 列表
* 必选：否
* 默认值：无
* **field**
* 描述：仅适用于多值场景下，表示数据迁移任务需要迁移的 Field 列表
* 必选：否
* 默认值：无
* **tag**
* 描述：数据迁移任务需要迁移的 TagK 和 TagV，用于进一步过滤时间线
* 必选：否
* 默认值：无
* **splitIntervalMs**
* 描述：用于 DataX 内部切分 Task，每个 Task 只查询一小部分的时间段
* 必选：是
* 默认值：无
* 注意：单位是 ms 毫秒
* **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、fields 和 value |
## 4 约束限制
### 4.2 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 TSDB 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 阿里云 TSDB 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 tsdb2stream.json -j "-Xms4096m -Xmx4096m"
```
### 4.3 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)`
