RisingWave vs Timeplus: Streaming Database Comparison (2026)
RisingWave is an open-source (Apache 2.0), self-hostable, PostgreSQL-compatible streaming database with disaggregated state on S3. Timeplus is a cloud-native streaming analytics platform with both open-source (Proton engine) and commercial offerings. Choose RisingWave for open-source flexibility, PostgreSQL ecosystem, and Iceberg integration. Choose Timeplus for an all-in-one cloud platform with built-in visualization.
Feature Comparison
| Feature | RisingWave | Timeplus |
| SQL dialect | PostgreSQL-compatible | ANSI SQL |
| Self-hosting | ✅ Full (Apache 2.0) | Limited (Proton engine only) |
| State storage | S3 (disaggregated) | Local / managed |
| CDC support | Native (PG, MySQL) | Via connectors |
| Iceberg sink | ✅ (5 catalog types) | ❌ |
| Built-in visualization | ❌ (use Grafana/Metabase) | ✅ Built-in dashboards |
| Vector search | ✅ (v2.6+) | ❌ |
| UDFs | Python, Java, Rust | JavaScript |
| Checkpoint interval | 1 second | Configurable |
Architecture Differences
RisingWave uses a disaggregated compute-storage architecture with state on S3. Compute nodes are stateless; state lives in object storage. This enables seconds-level recovery and elastic scaling.
Timeplus uses Proton as its core streaming engine with local state. The cloud platform adds visualization, alerting, and management layers on top.
When to Choose
RisingWave: You want open-source with no licensing restrictions, PostgreSQL compatibility, self-hosting, Iceberg/Delta Lake integration, or vector search capabilities.
Timeplus: You want an all-in-one platform with built-in dashboards and don't need self-hosting or lakehouse integration.
Frequently Asked Questions
Is Timeplus open source?
Timeplus Proton (the core engine) is open source. The full Timeplus platform (dashboards, management, cloud) is commercial. RisingWave is fully open source under Apache 2.0.
Which has better performance?
Both provide sub-second streaming latency. RisingWave's Nexmark benchmarks show it outperforms Flink in 22/27 queries. Timeplus publishes fewer public benchmarks.
Can I migrate from Timeplus to RisingWave?
If you're using Timeplus SQL, migration involves adapting SQL syntax to PostgreSQL dialect. Both support Kafka sources and materialized views.
