HeliosProxy vs Mycat2
Both stand on database proxy software. Which one you can start free with, which one lets you read the code, and what each costs once you pay.
HeliosProxy combines pooling, routing, caching, and failover controls for PostgreSQL-compatible systems. Check which session state is lost during failover when deciding whether its replay behavior fits your workloads.
Visit HeliosProxyChoose Mycat2 if you need free, open-source middleware for distributed SQL queries in a self-hosted Linux deployment. Its MySQL protocol support, query engine, and configurable algorithms are central capabilities. Consider its Java 8 runtime requirement and the stated ClickHouse auto-increment limitation when assessing fit.

HeliosProxy: what it does well
- Offers session, transaction, and statement pooling.
- Supports up to 100:1 connection multiplexing.
- Routes by replica lag and workload.
- Supports JWT, OAuth 2.0, LDAP, and API keys.
- Deploys with Docker, Kubernetes, or standalone.
What to know first
- Several kinds of session state are not restored after failover.
- Replay depends on conditions being suitable.
- Requires a self-hosted deployment.
Mycat2: what it does well
- Supports distributed SQL queries and the MySQL communication protocol.
- Connects to multiple backends through the Java ecosystem.
- Includes rule-based and cost-based query optimization.
- Supports connection pooling, query routing, and load balancing.
- Sharding and load balancing algorithms can be customized and loaded.
What to know first
- The README says the runtime supports Java 8 only.
- Deployment is self-hosted on Linux.
- ClickHouse support described in the v1.22 notes lacks returned auto-increment values.
