gcn-kafka 0.1.2

Kafka client for NASA's General Coordinates Network (GCN)

GCN Kafka Client for Python

This is the official Python client for the General Coordinates Network (GCN). It is a very lightweight wrapper around confluent-kafka-python.

To Install

Run this command to install with pip:

pip install gcn-kafka

To use

Create a consumer:

>>> from gcn_kafka import Consumer
>>> consumer = Consumer(client_id='fill me in', client_secret='fill me in')

List all topics:

>>> print(consumer.list_topics().topics)
{'gcn.classic.text.CALET_GBM_FLT_LC': TopicMetadata(gcn.classic.text.CALET_GBM_FLT_LC, 1 partitions), 'gcn.classic.voevent.FERMI_GBM_SUBTHRESH': TopicMetadata(gcn.classic.voevent.FERMI_GBM_SUBTHRESH, 1 partitions), ...}

Subscribe to topics and receive alerts:

>>> consumer.subscribe(['gcn.classic.text.FERMI_GBM_FIN_POS', 'gcn.classic.text.LVC_INITIAL'])
>>> while True:
...     for message in consumer.consume():
...         print(message.value())
