OssFile

Oss file source connector

Support Those Engines

Spark
Flink
SeaTunnel Zeta

Usage Dependency

For Spark/Flink Engine

1. You must ensure your spark/flink cluster already integrated hadoop. The tested hadoop version is 2.x.
2. You must ensure hadoop-aliyun-xx.jar, aliyun-sdk-oss-xx.jar and jdom-xx.jar in ${SEATUNNEL_HOME}/plugins/ dir and the version of hadoop-aliyun jar need equals your hadoop version which used in spark/flink and aliyun-sdk-oss-xx.jar and jdom-xx.jar version needs to be the version corresponding to the hadoop-aliyun version. Eg: hadoop-aliyun-3.1.4.jar dependency aliyun-sdk-oss-3.4.1.jar and jdom-1.1.jar.

For SeaTunnel Zeta Engine

1. You must ensure seatunnel-hadoop3-3.1.4-uber.jar, aliyun-sdk-oss-3.4.1.jar, hadoop-aliyun-3.1.4.jar and jdom-1.1.jar in ${SEATUNNEL_HOME}/lib/ dir.

Key features

• batch
• stream
• exactly-once

Read all the data in a split in a pollNext call. What splits are read will be saved in snapshot.

• column projection
• parallelism
• support user-defined split
• file format type
  • text
  • csv
  • parquet
  • orc
  • json
  • excel
  • xml
  • binary

Data Type Mapping

Data type mapping is related to the type of file being read, We supported as the following file types:

text csv parquet orc json excel xml

JSON File Type

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 can also save multiple pieces of data in one file and split them by newline:

{"code":  200, "data":  "get success", "success":  true}
{"code":  300, "data":  "get failed", "success":  false}

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

Text Or CSV File Type

If you set the file_format_type to text,excel,csv,xml. Then it's required to set the schema field to tell connector how to parse data to the row.

If you set the schema field, you should also set the option field_delimiter, except the file_format_type is csv, xml, excel

you can set schema and delimiter as the following:

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

connector will generate data as the following:

name	age	gender
tyrantlucifer	26	male

Orc File Type

If you assign file type to parquet orc, schema option not required, connector can find the schema of upstream data automatically.

Orc Data type	SeaTunnel Data type
BOOLEAN	BOOLEAN
INT	INT
BYTE	BYTE
SHORT	SHORT
LONG	LONG

compress_codec [string]

The compress codec of files and the details that supported as the following shown:

• txt: lzo none
• json: lzo none
• csv: lzo none
• orc/parquet:
  automatically recognizes the compression type, no additional settings required.

encoding [string]

Only used when file_format_type is json,text,csv,xml. The encoding of the file to read. This param will be parsed by Charset.forName(encoding).

file_filter_pattern [string]

Filter pattern, which used for filtering files.

The pattern follows standard regular expressions. For details, please refer to https://en.wikipedia.org/wiki/Regular_expression. There are some examples.

File Structure Example:

/data/seatunnel/20241001/report.txt
/data/seatunnel/20241007/abch202410.csv
/data/seatunnel/20241002/abcg202410.csv
/data/seatunnel/20241005/old_data.csv
/data/seatunnel/20241012/logo.png

Matching Rules Example:

Example 1: Match all .txt files，Regular Expression:

/data/seatunnel/20241001/.*\.txt

The result of this example matching is:

/data/seatunnel/20241001/report.txt

Example 2: Match all file starting with abc，Regular Expression:

/data/seatunnel/20241002/abc.*

The result of this example matching is:

/data/seatunnel/20241007/abch202410.csv
/data/seatunnel/20241002/abcg202410.csv

Example 3: Match all file starting with abc，And the fourth character is either h or g, the Regular Expression:

/data/seatunnel/20241007/abc[h,g].*

The result of this example matching is:

/data/seatunnel/20241007/abch202410.csv

Example 4: Match third level folders starting with 202410 and files ending with .csv, the Regular Expression:

/data/seatunnel/202410\d*/.*\.csv

The result of this example matching is:

/data/seatunnel/20241007/abch202410.csv
/data/seatunnel/20241002/abcg202410.csv
/data/seatunnel/20241005/old_data.csv

schema [config]

Only need to be configured when the file_format_type are text, json, excel, xml or csv ( Or other format we can't read the schema from metadata).

fields [Config]

The schema of upstream data.

How to Create a Oss Data Synchronization Jobs

The following example demonstrates how to create a data synchronization job that reads data from Oss and prints it on the local client:

# Set the basic configuration of the task to be performed
env {
  parallelism = 1
  job.mode = "BATCH"
}

# Create a source to connect to Oss
source {
  OssFile {
    path = "/seatunnel/orc"
    bucket = "oss://tyrantlucifer-image-bed"
    access_key = "xxxxxxxxxxxxxxxxx"
    access_secret = "xxxxxxxxxxxxxxxxxxxxxx"
    endpoint = "oss-cn-beijing.aliyuncs.com"
    file_format_type = "orc"
  }
}

# Console printing of the read Oss data
sink {
  Console {
  }
}

# Set the basic configuration of the task to be performed
env {
  parallelism = 1
  job.mode = "BATCH"
}

# Create a source to connect to Oss
source {
  OssFile {
    path = "/seatunnel/json"
    bucket = "oss://tyrantlucifer-image-bed"
    access_key = "xxxxxxxxxxxxxxxxx"
    access_secret = "xxxxxxxxxxxxxxxxxxxxxx"
    endpoint = "oss-cn-beijing.aliyuncs.com"
    file_format_type = "json"
    schema {
      fields {
        id = int 
        name = string
      }
    }
  }
}

# Console printing of the read Oss data
sink {
  Console {
  }
}

Multiple Table

No need to config schema file type, eg: orc.

env {

  spark.master = local
  job.mode = "BATCH"
}

source {
  OssFile {
    tables_configs = [
      {
          schema = {
              table = "fake01"
          }
          bucket = "oss://whale-ops"
          access_key = "xxxxxxxxxxxxxxxxxxx"
          access_secret = "xxxxxxxxxxxxxxxxxxx"
          endpoint = "https://oss-accelerate.aliyuncs.com"
          path = "/test/seatunnel/read/orc"
          file_format_type = "orc"
      },
      {
          schema = {
              table = "fake02"
          }
          bucket = "oss://whale-ops"
          access_key = "xxxxxxxxxxxxxxxxxxx"
          access_secret = "xxxxxxxxxxxxxxxxxxx"
          endpoint = "https://oss-accelerate.aliyuncs.com"
          path = "/test/seatunnel/read/orc"
