Get data from Amazon S3

Use the Amazon S3 source function to get data from Amazon S3 buckets. You must create a connection to use this source function. See Create a DSP connection to get data from Amazon S3 in the Connect to Data Sources and Destinations with DSP manual.

The source function collects data from S3 according to the job schedule defined in the connection, and identifies the new data to collect based on S3 event notifications conveyed through Amazon Simple Queue Service (SQS). See How Amazon S3 data is collected in the Connect to Data Sources and Destinations with DSP manual for more information.

Function output schema

This function outputs data pipeline events using the event schema.

In the attributes field, the function includes the following attributes in addition to the ones that are part of the original payload:

  • accountID: The ID of the AWS account associated with the event. This attribute is returned as an empty string ("") if the account ID cannot be retrieved.
  • lastModified: The date and time when the Amazon S3 file was last modified, given in epoch time format in seconds.
  • etag: The entity tag (ETag) associated with the Amazon S3 file.

The following is an example of a typical record from the read_from_aws_s3 function:

{
"timestamp": 1562975395000,
"nanos": 0,
"id": "2823738566644596",
"host": "test-host-1",
"source": "https://s3.us-east-1.amazonaws.com/bucket/test/log.gz",
"source_type": "aws:s3:plaintext",
"kind": "event",
"body": "helloworld",
"attributes": {
     "accountID": "123412341234",
     "lastModified": 1562717968,
     "etag": "brvlvj6883e6pa6u47fr0vvmaky891vr"
     }
}

Required arguments

connection_id
Syntax: string
Description: The ID of your Amazon S3 connection.
Example: "576205b3-f6f5-4ab7-8ffc-a4089a95d0c4"

Optional arguments

initial_position
Syntax: LATEST | TRIM_HORIZON
Description: The position in the data stream where you want to start reading data. Defaults to LATEST.
  • LATEST: Start reading data from the latest position on the data stream.
  • TRIM_HORIZON: Start reading data from the very beginning of the data stream.
Example: LATEST

SPL2 example

You can write the function by listing arguments in this exact order.

| from read_from_aws_s3("my-connection-id", "TRIM_HORIZON") |... ;

Alternatively, you can use named arguments in any order, and omit the optional argument if you just want to use the default value. See the "Named arguments" section in SPL2 syntax for more details. The following SPL2 example omits the initial_position argument.

| from read_from_aws_s3(connection_id: "my-connection-id") |... ;

Limitations of the Amazon S3 source function

The Amazon S3 source function uses scheduled data collection jobs to ingest data. See Limitations of scheduled data collection jobs for information about limitations that apply to all scheduled data collection jobs.
