Ftp file source connector


Read data from ftp file server.


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.

Key features​

host [string]​

The target ftp host is required

port [int]​

The target ftp port is required

username [string]​

The target ftp username is required

password [string]​

The target ftp 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]​

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


Tips: Do not define partition fields in schema option

date_format [string]​

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

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

default yyyy-MM-dd

datetime_format [string]​

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 excel

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:

200get successtrue

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:


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


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:

path = "/tmp/seatunnel/sink/text"
host = ""
port = 21
user = tyrantlucifer
password = tianchao
file_format_type = "text"
schema = {
