error from persister

Error message

error from persister: {0}

What it means

This error wraps a PersisterError raised while the write buffer interacts with its persistence layer (the component that durably stores buffered data and catalog operations, typically backed by object storage). It indicates the failure happened below the buffering layer, in durable persistence, and the underlying PersisterError is preserved via `#[from]`.

Solutions

1. Read the inner PersisterError to identify which persistence operation failed
2. Verify object-store configuration (endpoint, bucket, credentials, region)
3. Check network connectivity and storage-backend rate limits/quotas
4. Retry the operation; most persister failures are transient

Example fix

// before
let buf = WriteBuffer::new(...)?; // panics with opaque message on persist failure
// after
match WriteBuffer::new(...) {
    Err(WriteBufferError::PersisterError(pe)) => {
        eprintln!("persister unavailable: {pe}; check object store config");
        std::process::exit(1);
    }
    r => r?,
}

// before starting, verify persister backend reachable
object_store.head(&persist_path).await
    .expect("persister object store not reachable; check config/credentials");

match result {
    Err(WriteBufferError::PersisterError(e)) => {
        warn!("persister failed: {e}");
        retry_with_backoff(op); // transient storage failures
    }
    other => other?,
}

When it happens

Trigger: Any write-buffer operation that persists data or catalog mutations and the persister fails: flushing buffered writes, persisting catalog operations, loading persisted state at startup, or WAL/persist interactions during writes.

Common situations: Object storage (S3/GCS/Local) credentials expired or bucket misconfigured; network partition to storage backend; bucket/container deleted or permissions changed; storage rate limits hit under heavy ingest.
