target-s3-jsonl

Singer target that uploads loads data to S3 in JSONL format following the Singer spec.

target-s3-jsonl is a Singer Target which intend to work with regular Singer Tap. It take the output of the tap and export it as a JSON Lines files into an AWS S3 bucket.

This package is built using the target-core library.

Install

First, make sure Python 3 is installed on your system or follow these installation instructions for Mac or Ubuntu.

Defaults

Note: To avoid version conflicts run tap and targets in separate virtual environments.

python -m venv ~/.virtualenvs/target-s3-jsonl
~/.virtualenvs/target-s3-jsonl/bin/pip install target-s3-jsonl

Head

python -m venv ~/.virtualenvs/target-s3-jsonl
~/.virtualenvs/target-s3-jsonl/bin/pip install --upgrade git+https://github.com/ome9ax/target-s3-jsonl.git@main

Alternative

python -m venv ~/.virtualenvs/target-s3-jsonl
source ~/.virtualenvs/target-s3-jsonl/bin/activate
pip install target-s3-jsonl
deactivate

Usage

Like any other target that's following the singer specificiation:

some-singer-tap | target-s3-jsonl --config [config.json]

It's reading incoming messages from STDIN and using the properites in config.json to upload data into AWS S3.

Configuration settings

Running the the target connector requires a config.json file. An example with the minimal settings:

{
    "s3_bucket": "my_bucket"
}

Profile based authentication

Profile based authentication used by default using the default profile. To use another profile set aws_profile parameter in config.json or set the AWS_PROFILE environment variable.

Non-Profile based authentication

For non-profile based authentication set aws_access_key_id , aws_secret_access_key and optionally the aws_session_token parameter in the config.json. Alternatively you can define them out of config.json by setting AWS_ACCESS_KEY_ID, AWS_SECRET_ACCESS_KEY and AWS_SESSION_TOKEN environment variables.

Inherited from target-core

Property	Type	Mandatory?	Description
path_template	String		(Default: None) Custom naming convention of the s3 key. Replaces tokens stream, and date_time with the appropriate values. Supports datetime and other python advanced string formatting e.g. {stream}_{date_time:%FT%T.%f}.jsonl or {stream:_>8}/{date_time:%Y}/{date_time:%m}/{date_time:%d}/{date_time:%Y%m%d_%H%M%S_%f}.json. Supports "folders" in s3 keys e.g. my_folder/my_sub_folder/{stream}/export_date={date}/{date_time}.json.
memory_buffer	Integer		Memory buffer's size used for non partitioned files before storing the data into the temporary file. 64Mb used by default if unspecified.
file_size	Integer		File partitinoning by size_limit. File parts will be created. The path_template must contain a part section for the part number. Example "path_template": "{stream}_{date_time:%Y%m%d_%H%M%S}_part_{part:0>3}.json".
compression	String		The type of compression to apply before uploading. Supported options are none (default), gzip, and lzma. For gzipped files, the file extension will automatically be changed to .json.gz for all files. For lzma compression, the file extension will automatically be changed to .json.xz for all files.
timezone_offset	Integer		Offset value in hour. Use offset 0 hours is you want the path_template to use utc time zone. The null values is used by default.
work_dir	String		(Default: platform-dependent) Directory for temporary JSONL files with RECORD messages.

Property	Type	Mandatory?	Description
s3_bucket	String	Yes	S3 Bucket name
aws_profile	String		AWS profile name for profile based authentication. If not provided, AWS_PROFILE environment variable will be used.
aws_endpoint_url	String		AWS endpoint URL.
aws_access_key_id	String		S3 Access Key Id. If not provided, AWS_ACCESS_KEY_ID environment variable will be used.
aws_secret_access_key	String		S3 Secret Access Key. If not provided, AWS_SECRET_ACCESS_KEY environment variable will be used.
aws_session_token	String		AWS Session token. If not provided, AWS_SESSION_TOKEN environment variable will be used.
encryption_type	String		(Default: 'none') The type of encryption to use. Current supported options are: 'none' and 'KMS'.
