Sftp file source connector

Description

Read data from sftp file server.

:::tip

If you use spark/flink, In order to use this connector, You must ensure your spark/flink cluster already integrated hadoop. The tested hadoop version is 2.x.

If you use SeaTunnel Engine, It automatically integrated the hadoop jar when you download and install SeaTunnel Engine. You can check the jar package under ${SEATUNNEL_HOME}/lib to confirm this.

host [string]

The target sftp host is required

port [int]

The target sftp port is required

username [string]

The target sftp username is required

password [string]

The target sftp password is required

path [string]

The source file path.

delimiter [string]

Field delimiter, used to tell connector how to slice and dice fields when reading text files

default \001, the same as hive's default delimiter

parse_partition_from_path [boolean]

Control whether parse the partition keys and values from file path

For example if you read a file from path sftp://hadoop-cluster/tmp/seatunnel/parquet/name=tyrantlucifer/age=26

Every record data from file will be added these two fields:

name age
tyrantlucifer 26

Tips: Do not define partition fields in schema option

date_format [string]

yyyy-MM-dd yyyy.MM.dd yyyy/MM/dd

default yyyy-MM-dd

datetime_format [string]

yyyy-MM-dd HH:mm:ss yyyy.MM.dd HH:mm:ss yyyy/MM/dd HH:mm:ss yyyyMMddHHmmss

default yyyy-MM-dd HH:mm:ss

time_format [string]

Time type format, used to tell connector how to convert string to time, supported as the following formats:

HH:mm:ss HH:mm:ss.SSS

default HH:mm:ss

skip_header_row_number [long]

Skip the first few lines, but only for the txt and csv.

For example, set like following:

skip_header_row_number = 2

then Seatunnel will skip the first 2 lines from source files

schema [config]

The schema information of upstream data.

read_columns [list]

The read column list of the data source, user can use it to implement field projection.

The file type supported column projection as the following shown:

  • text
  • json
  • csv
  • orc
  • parquet
  • excel

Tips: If the user wants to use this feature when reading text json csv files, the schema option must be configured

file_format_type [string]

File type, supported as the following file types:

text csv parquet orc json

If you assign file type to json, you should also assign schema option to tell connector how to parse data to the row you want.

For example:

upstream data is the following:

{"code":  200, "data":  "get success", "success":  true}

you should assign schema as the following:

schema {
    fields {
        code = int
        data = string
        success = boolean
    }
}

connector will generate data as the following:

code data success
200 get success true

If you assign file type to text csv, you can choose to specify the schema information or not.

For example, upstream data is the following:


tyrantlucifer#26#male

If you do not assign data schema connector will treat the upstream data as the following:

content
tyrantlucifer#26#male

If you assign data schema, you should also assign the option delimiter too except CSV file type

you should assign schema and delimiter as the following:

delimiter = "#"
schema {
    fields {
        name = string
        age = int
        gender = string 
    }
}

connector will generate data as the following:

name age gender
tyrantlucifer 26 male

common options

Source plugin common parameters, please refer to Source Common Options for details.

sheet_name [string]

Reader the sheet of the workbook,Only used when file_format is excel.

Example

  SftpFile {
    path = "/tmp/seatunnel/sink/text"
    host = "192.168.31.48"
    port = 21
    user = tyrantlucifer
    password = tianchao
    file_format_type = "text"
    schema = {
      name = string
      age = int
    }
    delimiter = "#"
  }
