Q: Considering performance only, can a MySQL Cluster beat a custom data sharding MySQL solution?
A: I would say that MySQL Cluster could achieve higher throughput/host than sharded MySQL+InnoDB provided that :
- Queries are simple
- All data fits in-memory
In terms of latency, MySQL Cluster should have more stable latency than sharded MySQL. Actual latencies for purely in-memory data could be similar. As queries become more complex, and data is stored on disk, the performance comparison becomes more confusing.
