Serialize/deserialize error

Error message

Serialize/deserialize error: {0}

What it means

BatchError::Serde variant: serialization or deserialization of batch exchange data (chunks shuffled between frontend and compute nodes via protobuf/arrow IPC) failed. The underlying failure comes from a boxed third-party or data-conversion error attached as source; typical causes are schema mismatches between producer and consumer, unsupported data types, or corrupt payload bytes in the exchange channel.

Solutions

1. Check that producer and consumer agree on the schema and data types of exchanged chunks
2. Inspect the boxed source error to identify whether the failure is in arrow/prost serialization or conversion
3. Enable debug logging on the exchange channel to capture the failing payload
4. Verify RisingWave cluster nodes are running the same version if errors appear after an upgrade
