IBM Streams Avro integration

Project description


Provides functions for serialization and deserialization of messages in an Apache Avro format.

This package exposes the toolkit as Python methods for use with Streaming Analytics service on IBM Cloud and IBM Streams including IBM Cloud Pak for Data.


A simple example of a Streams application that serializes and deserializes messages:

from streamsx.topology.topology import *
from streamsx.topology.schema import CommonSchema, StreamSchema
from streamsx.topology.context import submit
import streamsx.avro as avro

topo = Topology()

avro_schema = '{"type" : "record", "name" : "hw_schema", "fields" : [{"name" : "a", "type" : "string"}]}'
s = topo.source([{'a': 'Hello'}, {'a': 'World'}, {'a': '!'}]).as_json()

# convert json to avro blob
o = avro.json_to_avro(s, avro_schema)
# convert avro blob to json
res = avro.avro_to_json(o, avro_schema)

# Use for IBM Streams including IBM Cloud Pak for Data
# submit ('DISTRIBUTED', topo, cfg)
