Storage error: {0}

Error message

Storage error: {0}

What it means

`ErrorKind::Storage` is a variant of the stream executor error enum (`StreamExecutorError`) that wraps a `StorageError` with the message "Storage error: {0}". It is the standard conversion (via `#[from]`) whenever any state-table/Hummock storage operation inside a streaming executor fails, and it carries the underlying error and backtrace.

Solutions

1. Read the inner StorageError in the log to identify the root cause (network, auth, timeout) and fix the storage backend.
2. Verify object-store connectivity and credentials (S3/MinIO endpoint, keys, region) in the RisingWave config.
3. Check meta node and compactor health; restart failed components after fixing the underlying storage issue.
4. If the error is retryable (epoch conflict), RisingWave usually retries automatically — persistent occurrences mean a real storage fault.

// Pre-flight: verify the object store is reachable before starting RisingWave
// e.g. aws s3 ls s3://<hummock-bucket> or mc ls local/minio

// RisingWave retries retryable storage errors internally; operators should:
// 1) alert on persistent 'Storage error:' logs, 2) check meta/compactor/object store health,
// 3) restart affected components after the backend recovers.

When it happens

Trigger: Any state table read/write inside a stream executor failing — e.g., Hummock SST lookups, epoch advance/retryable errors, remote object-store I/O failures, or state table schema mismatches — automatically converted into a StreamExecutorError through the `From<StorageError>` impl.

Common situations: Object store (S3/MinIO/OSS) outages or bad credentials; Hummock compaction or read timeouts under load; meta node/network failures breaking state table access; running with a misconfigured storage backend endpoint.
