scimma-client 0.0.4a3

A client library for SCiMMA

SCiMMA Client

scimma-client is a pub-sub client library for Multimessenger Astrophysics.

Quickstart

Publish a GCN to Kafka:

scimma publish kafka://hostname:port/gcn mygcn.gcn3

Subscribe to the earliest offset of a Kafka topic and print to stdout:

scimma subscribe kafka://hostname:port/gcn -e

An example RFC 822 formatted GCN circular (example.gcn3) is provided in tests/data.

Client configuration properties can be passed to scimma publish via -X property=value or in a configuration file specified by -F <config-file>, mimicking the behavior of kafkacat. This can be used to connect to a Kafka broker with SSL authentication enabled, for example.

Installation

You can install scimma-client either via pip, conda, or from source.

To install with pip:
