When should I use AWS Kinesis instead of Pravega?

Managed real-time data streaming on AWS with per-shard scalability and no Kafka to operate. Teams in the AWS ecosystem needing event streaming integrated with Lambda, Firehose, and Redshift. Serverless stream processing where Kinesis Data Analytics handles SQL or Flink queries

When should I use Pravega instead of AWS Kinesis?

Long-term durable stream storage combining message queue and database semantics. IoT and sensor telemetry workloads needing indefinite retention and historical replay. Streams that need both real-time consumption and efficient random-access historical reads

What are the main weaknesses of AWS Kinesis?

Per-shard billing becomes expensive for high-volume or very bursty workloads. Retention is capped at 365 days maximum — Kafka is better for indefinite event log retention. Vendor lock-in: Kinesis API is AWS-specific with no portable alternative

What are the main weaknesses of Pravega?

Niche tool with a small community and limited ecosystem integrations compared to Kafka. Requires running the Pravega streaming storage server alongside your application. Less production-proven than Kafka for mainstream event streaming use cases

How Python Data Engineers Use These Tools

AWS Kinesis

Python data engineers use `boto3`'s Kinesis client to put records onto a Data Stream from Lambda functions or EC2-based producers. Consumer applications use the Kinesis Client Library (KCL) with Python bindings, or the `amazon-kinesis-client` Python wrapper, to process shards in parallel with automatic checkpointing — a common pattern for real-time log processing and event enrichment.

Pravega

Python data engineers use the `pravega-grpc-gateway` or Python client to produce durable event streams to Pravega. Unlike Kafka, Pravega retains streams indefinitely with cost-tiered storage — Python pipelines use this for event sourcing architectures where the full history of events must be replayable for reprocessing after logic changes.
