Amazon Kinesis vs RisingWave for Stream Processing
Amazon Kinesis is AWS's managed streaming service for real-time data ingestion and processing. RisingWave is an open-source streaming database with PostgreSQL compatibility. Use Kinesis for AWS-native, fully managed event ingestion. Use RisingWave for SQL-based stream processing with built-in serving and CDC support.
Comparison
| Feature | Amazon Kinesis | RisingWave |
| Type | Managed streaming service | Streaming database |
| Deployment | AWS only | Anywhere (open source) |
| Processing | Kinesis Data Analytics (Flink) | Built-in SQL engine |
| SQL | Flink SQL (via KDA) | PostgreSQL-compatible |
| Serving | ❌ (needs external DB) | ✅ Built-in |
| CDC | ❌ | ✅ Native |
| Pricing | Per shard-hour | Compute + S3 |
| Vendor lock-in | High (AWS) | None (open source) |
| Throughput | 1 MB/sec per shard | Horizontally scalable |
When to Choose
Kinesis: You're fully on AWS, want zero infrastructure management, and need simple event ingestion + basic processing.
RisingWave: You need SQL-based streaming with serving, CDC from databases, multi-cloud/self-hosted deployment, or want to avoid AWS lock-in.
Frequently Asked Questions
Can RisingWave read from Kinesis?
Yes. RisingWave supports Amazon Kinesis as a source connector, allowing you to process Kinesis streams with PostgreSQL SQL.
Is Kinesis cheaper than RisingWave?
For low-volume workloads, Kinesis pay-per-shard can be cheaper. For high-volume sustained workloads, RisingWave (self-hosted) is typically more cost-effective since you pay only for compute + S3.
