Storage error: {0}

Error message

Storage error: {0}

What it means

BatchError::Storage wraps a StorageError into the batch engine's error type via thiserror's #[from], displaying as "Storage error: {0}". It surfaces when a batch query's executor hits a storage-layer failure (object store, Hummock, read errors) while fetching data.

Solutions

1. Read the wrapped StorageError message for the root cause and fix the underlying storage issue (credentials, endpoint, connectivity).
2. Verify object-store configuration (endpoint, region, keys) in the compute node config.
3. Check Hummock/meta service health and retry the query once storage recovers.
4. If an SST or data file is reported missing/corrupt, follow RisingWave's state-store recovery guidance.

Example fix

// before: wrong/missing S3 endpoint in risingwave.toml
[state_store]
= "s3://bucket"
// after: valid endpoint and credentials
[state_store]
= "s3://bucket"
// plus S3_ENDPOINT, S3_ACCESS_KEY, S3_SECRET set correctly

// Rust: pre-flight object store connectivity check
let ok = tonic_health::check_storage_endpoint(&endpoint).await.is_ok();
if !ok { /* fix endpoint/credentials before running batch queries */ }

match query_result {
    Err(BatchError::Storage(storage_err)) => {
        // inspect storage_err root cause; retry with backoff for transient I/O
    }
    other => other,
}

When it happens

Trigger: Any storage operation invoked from the batch path returns Err(StorageError) and is converted with `?` — e.g. Hummock reads, SST lookups, object-store I/O during a table scan.

Common situations: Object store (S3/MinIO) misconfiguration or outage; network issues between compute and storage; state store unavailability during batch queries on materialized views; corrupted or missing SST files.
