FtpFile

Ftp文件数据接收器连接器

描述

将数据输出到FTP。

:::提示

如果你使用Spark或Flink,为了使用这个连接器,你必须确保你的Spark或Flink集群已经集成了Hadoop。经测试的Hadoop版本是2.x版本。

如果你使用SeaTunnel引擎,在你下载并安装SeaTunnel引擎时,它会自动集成Hadoop的jar包。你可以查看${SEATUNNEL_HOME}/lib目录下的jar包来确认这一点。

:::

host [string]

目标FTP主机是必需的。

port [int]

目标FTP端口是必需的。

user [string]

目标FTP用户名是必需的。

password [string]

目标FTP密码是必需的。

path [string]

目标目录路径是必需的。

connection_mode [string]

目标 FTP 连接模式是必需的,默认值为主动模式,支持以下几种模式:

active_local(本地主动模式) passive_local(本地被动模式)

custom_filename [boolean]

是否自定义文件名

file_name_expression [string]

仅当 custom_filenametrue时使用。

file_name_expression描述了将在 path中创建的文件表达式。我们可以在 file_name_expression 中添加变量 ${now}${uuid},例如 test_${uuid}_${now}

${now} 表示当前时间,其格式可以通过指定选项 filename_time_format来定义。

请注意,如果 is_enable_transactiontrue,我们将自动在文件名的开头添加 ${transactionId}_

filename_time_format [string]

仅当 custom_filenametrue时才会用到。

file_name_expression 参数中的格式为 xxxx-${now} 时,filename_time_format 可以指定路径的时间格式,其默认值为 yyyy.MM.dd 。常用的时间格式列举如下:

代表符号描述
yYear
MMonth
dDay of month
HHour in day (0-23)
mMinute in hour
sSecond in minute

file_format_type [string]

我们支持以下文件类型:

text csv parquet orc json excel xml binary

请注意,最终的文件名将会以 file_format_type 的后缀结尾,文本文件的后缀是 txt

field_delimiter [string]

一行数据中各列之间的分隔符。仅 text文件格式需要用到。

row_delimiter [string]

一行数据中各列之间的分隔符。仅在text文件格式中需要用到。

have_partition [boolean]

你是否需要对分区进行处理。

partition_by [array]

仅在 have_partitiontrue 时才使用。

根据选定的字段对数据进行分区。

partition_dir_expression [string]

仅在 have_partitiontrue 时使用。

若指定了 partition_by,我们会根据分区信息生成相应的分区目录,最终文件将被放置在该分区目录中。

默认的 partition_dir_expression${k0}=${v0}/${k1}=${v1}/.../${kn}=${vn}/。其中,k0 是第一个分区字段,v0 是第一个分区字段的值。

is_partition_field_write_in_file [boolean]

仅在 have_partitiontrue 时使用。

如果 is_partition_field_write_in_filetrue,那么分区字段及其对应的值将被写入数据文件中。

例如,如果你想要写入一个 Hive 数据文件,该值(is_partition_field_write_in_file)应该设为 false

sink_columns [array]

哪些列需要写入文件,默认值是从 TransformSource 获取的所有列。

字段的顺序决定了实际写入文件时的顺序。

is_enable_transaction [boolean]

如果 is_enable_transactiontrue),我们将确保在数据写入目标目录时不会丢失或重复。

请注意,如果 is_enable_transactiontrue,我们将自动在文件名开头添加 ${transactionId}_

目前仅支持 true这一选项。

batch_size [int]

一个文件中的最大行数。对于 SeaTunnel 引擎,文件中的行数由 batch_sizecheckpoint.interval 共同决定。如果 checkpoint.interval 的值足够大,sink writer 会向一个文件中写入行,直到文件中的行数超过 batch_size。如果 checkpoint.interval 较小,当新的检查点触发时,sink writer 会创建一个新文件。

compress_codec [string]

文件的压缩编解码器及其所支持的详细情况如下:

文件的压缩编解码器以及所支持的详细信息如下所示:

  • txt:lzo none

  • json:lzo none

  • csv:lzo none

  • orc:lzo snappy lz4 zlib none

  • parquet:lzo snappy lz4 gzip brotli zstd none `

    提示:Excel 类型不支持任何压缩格式。

common options

Sink 插件的通用参数,请参考Sink通用选项了解详细信息。

max_rows_in_memory [int]

当文件格式为Excel时,可在内存中缓存的数据项的最大数量。

sheet_name [string]

写入工作簿的工作表。

csv_string_quote_mode [string]

当文件格式为CSV时,CSV的字符串引号模式:

  • ALL(全部):所有字符串字段都将被加上引号。
  • MINIMAL(最少):仅对包含特殊字符(如字段分隔符、引号字符或行分隔字符串中的任何字符)的字段加上引号。
  • NONE(无):从不对字段加引号。当数据中出现分隔符时,打印程序会在其前面加上转义字符。如果未设置转义字符,格式验证将抛出异常。

xml_root_tag [string]

指定 XML 文件中根元素的标签名称。

xml_row_tag [string]

指定 XML 文件中数据行的标签名称。

xml_use_attr_format [boolean]

指定是否使用标签属性格式来处理数据。

parquet_avro_write_timestamp_as_int96 [boolean]

支持从时间戳写入 Parquet 格式的 INT96 类型数据,仅对 Parquet 文件有效。

parquet_avro_write_fixed_as_int96 [array]

支持从一个12字节的字段写入Parquet的INT96类型数据,仅对Parquet文件有效。

enable_header_write [boolean]

仅当文件格式类型为文本或CSV时使用。 false:不写入表头,true:写入表头。

encoding [string]

仅当文件格式类型为JSON、文本、CSV、XML时才使用。

要写入的文件的编码。此参数将由 Charset.forName(encoding) 方法进行解析。

schema_save_mode [string]

现有目录处理方法:

  • RECREATE_SCHEMA(重新创建模式):目录不存在时创建;目录存在时,删除并重新创建。
  • CREATE_SCHEMA_WHEN_NOT_EXIST(不存在时创建模式):目录不存在时创建;目录存在时跳过处理
  • ERROR_WHEN_SCHEMA_NOT_EXIST(模式不存在时出错):目录不存在时报告错误。
  • IGNORE(忽略):忽略对该表的处理。

data_save_mode [string]

现有数据处理方法:

  • DROP_DATA(删除数据):保留目录,删除数据文件。
  • APPEND_DATA(追加数据):保留目录和数据文件。
  • ERROR_WHEN_DATA_EXISTS(数据存在时报错):当存在数据文件时,报告错误。

示例

对于文本文件格式的简易配置


FtpFile {
host = "xxx.xxx.xxx.xxx"
port = 21
user = "username"
password = "password"
path = "/data/ftp"
file_format_type = "text"
field_delimiter = "\t"
row_delimiter = "\n"
sink_columns = ["name","age"]
}

对于带有 have_partitioncustom_filenamesink_columns 的文本文件格式


FtpFile {
host = "xxx.xxx.xxx.xxx"
port = 21
user = "username"
password = "password"
path = "/data/ftp/seatunnel/job1"
tmp_path = "/data/ftp/seatunnel/tmp"
file_format_type = "text"
field_delimiter = "\t"
row_delimiter = "\n"
have_partition = true
partition_by = ["age"]
partition_dir_expression = "${k0}=${v0}"
is_partition_field_write_in_file = true
custom_filename = true
file_name_expression = "${transactionId}_${now}"
sink_columns = ["name","age"]
filename_time_format = "yyyy.MM.dd"
}

当我们的数据源端是多个表,并且希望将不同的数据按照不同的表达式存储到不同的目录时,我们可以按照这种方式进行配置。


FtpFile {
host = "xxx.xxx.xxx.xxx"
port = 21
user = "username"
password = "password"
path = "/data/ftp/seatunnel/job1/${table_name}"
tmp_path = "/data/ftp/seatunnel/tmp"
file_format_type = "text"
field_delimiter = "\t"
row_delimiter = "\n"
have_partition = true
partition_by = ["age"]
partition_dir_expression = "${k0}=${v0}"
is_partition_field_write_in_file = true
custom_filename = true
file_name_expression = "${transactionId}_${now}"
sink_columns = ["name","age"]
filename_time_format = "yyyy.MM.dd"
schema_save_mode=RECREATE_SCHEMA
data_save_mode=DROP_DATA
}
