It just got even simpler for Python developers to build powerful streaming data apps
Redpanda's achievements have always captivated our attention. It appears that the same community drawn to Bytewax also tends to be attracted to Redpanda. As an Apache Kafka®-compatible event streaming platform, Redpanda streamlines the data management process, eliminating the need for Apache Zookeeper®, JVM, and any code alterations while supporting all favored open-source tools.
Recognizing this shared audience and technological compatibility, we've taken a step to integrate Redpanda more deeply into Bytewax. This blog post highlights how easily Redpanda and Bytewax click together, with an emphasis on the recently released Schema Registry integration in the latest v0.18 release.
Redpanda's Schema Registry is essential for managing schema and ensuring data integrity in streaming contexts. It centralizes schema management, facilitating easy access and sharing between producers and consumers. This setup enhances message serialization/deserialization and maintains compatibility across schema versions, supporting seamless schema evolution.
The registry uses a systematic approach to manage schema changes, allowing applications to adapt without data pipeline disruption. It organizes schemas in defined namespaces and tracks their versions, streamlining schema version control and ensuring data remains consistent and structured for evolving data models.

The Schema Registry allows consumers and producers to access schemas using a RESTful API
The integration between Bytewax and Redpanda, particularly with the Redpanda Schema Registry, offers several key benefits:
To get this powerful integration up and running, developers can simply connect their Bytewax dataflows to Redpanda streams using the native support for the Redpanda Schema Registry. This ensures that data is automatically serialized and deserialized according to the schemas defined in the registry, facilitating a smooth and efficient data processing pipeline.
import bytewax.operators as op
from bytewax.connectors.kafka import operators as rop
from bytewax.connectors.kafka.registry import RedpandaSchemaRegistry, SchemaRef
REDPANDA_BROKERS = os.environ.get("REDPANDA_SERVER", "localhost:19092").split(";")
IN_TOPICS = os.environ.get("REDPANDA_IN_TOPIC", "in_topic").split(";")
REDPANDA_REGISTRY_URL = os.environ["REDPANDA_REGISTRY_URL"]
flow = Dataflow("schema_registry")
rinp = rop.input("redpanda-in", flow, brokers=REDPANDA_BROKERS, topics=IN_TOPICS)
# Inspect errors and crash
op.inspect("inspect-rp-errors", rinp.errs).then(op.raises, "redpanda-error")
# Redpanda's schema registry configuration
registry = RedpandaSchemaRegistry(REDPANDA_REGISTRY_URL)
# Deserialize both key and value
key_de = registry.deserializer(SchemaRef("sensor-key"))
val_de = registry.deserializer(SchemaRef("sensor-value"))
msgs = kop.deserialize("de", rinp.oks, key_deserializer=key_de, val_deserializer=val_de)
# Inspect errors and crash
op.inspect("inspect-deser", msgs.errs).then(op.raises, "deser-error")The Bytewax and Redpanda partnership, especially the native integration with the Redpanda Schema Registry, marks a significant milestone for Python developers building streaming data solutions. By combining the strengths of both platforms, we’re making it easier for developers to build high-performance, scalable, and reliable applications. We invite you to explore this new integration and discover how it can benefit your projects!
