ClickhouseFile

Clickhouse文件数据接收器

描述​

该接收器使用clickhouse-local程序生成clickhouse数据文件，随后将其发送至clickhouse服务器，这个过程也称为bulkload。该接收器仅支持表引擎为 'Distributed'的表，且internal_replication选项需要设置为true。支持批和流两种模式。

主要特性​

提示

你也可以采用JDBC的方式将数据写入Clickhouse。

host [string]​

ClickHouse集群地址，格式为host:port，允许同时指定多个hosts。例如"host1:8123,host2:8123"。

database [string]​

ClickHouse数据库名。

table [string]​

表名称。

username [string]​

连接ClickHouse的用户名。

password [string]​

连接ClickHouse的用户密码。

sharding_key [string]​

当ClickhouseFile需要拆分数据时，需要考虑的问题是当前数据需要发往哪个节点，默认情况下采用的是随机算法，我们也可以使用'sharding_key'参数为某字段指定对应的分片算法。

clickhouse_local_path [string]​

在spark节点上的clickhouse-local程序路径。由于每个任务都会被调用，所以每个spark节点上的clickhouse-local程序路径必须相同。

copy_method [string]​

为文件传输指定方法，默认为scp，可选值为scp和rsync。

node_free_password [boolean]​

由于seatunnel需要使用scp或者rsync进行文件传输，因此seatunnel需要clickhouse服务端访问权限。如果每个spark节点与clickhouse服务端都配置了免密登录，则可以将此选项配置为true，否则需要在node_pass参数中配置对应节点的密码。

node_pass [list]​

用来保存所有clickhouse服务器地址及其对应的访问密码。

node_pass.node_address [string]​

clickhouse服务器节点地址。

node_pass.username [string]​

clickhouse服务器节点用户名，默认为root。

node_pass.password [string]​

clickhouse服务器节点的访问密码。

compatible_mode [boolean]​

在低版本的Clickhouse中，clickhouse-local程序不支持--path参数，需要设置该参数来采用其他方式实现--path参数功能。

file_fields_delimiter [string]​

ClickHouseFile使用CSV格式来临时保存数据。但如果数据中包含CSV的分隔符，可能会导致程序异常。使用此配置可以避免该情况。配置的值必须正好为一个字符的长度。

file_temp_path [string]​

ClickhouseFile本地存储临时文件的目录。

key_path [string]​

用于scp或rsync传输文件的私钥路径。

common options​

Sink插件常用参数，请参考Sink常用选项获取更多细节信息。

示例​

ClickhouseFile {
  host = "192.168.0.1:8123"
  database = "default"
  table = "fake_all"
  username = "default"
  password = ""
  clickhouse_local_path = "/Users/seatunnel/Tool/clickhouse local"
  sharding_key = "age"
  node_free_password = false
  node_pass = [{
    node_address = "192.168.0.1"
    password = "seatunnel"
  }]
}
