Kinesis utilities

Project description

PyPI

Miscellaneous utilities for AWS Kinesis.

Installation

pip install kinesisutils

To install the development version:

pip install git+https://github.com/findhotel/kinesisutils

Usage

At the moment there is only one utility implemented: a Python generator that reads records from a Kinesis stream. You can use it like this:

import json

from kinesisutils.kinesisutils import KinesisGenerator

# Hit Kinesis with at most 10 requests per second, usin json.loads to
# deserialize the Kinesis records (the default). You could deactivate record
# deserialization by setting des=None.
kg = KinesisGenerator("stream_name", rqs=10, des=json.loads)

for rec in kg:
    print(rec)

By default the generator will keep pulling records from Kinesis for 60 seconds. You can customize this timeout if you want:

from kinesisutils.kinesisutils import KinesisGenerator

kg = KinesisGenerator("stream_name", timeout=30)

for rec in kg:
    print(rec)

If you are using the Kinesis generator to read Cloudwatch log events that are being forwarded to a Kinesis stream using a [logs subscription][logsubs] you will need to decompress the Cloudwatch records before deserializing them:

import decompress
import json

kg = KinesisGenerator("stream_name", rqs=10, des=json.loads,
                      preprocess=gzip.decompress)

for rec in kg:
    print(rec)
