ordered catalog batch should contain changes

Error message

ordered catalog batch should contain changes

What it means

This panic fires when an ordered catalog batch, which has already been validated by apply_catalog_batch, returns None (no changes) instead of a CatalogBatch. The library considers a successfully-applied ordered batch to always contain at least one change; an empty result indicates a corrupted or out-of-order batch stream, so it panics rather than silently proceeding.

Solutions

1. Verify the batch being replayed is not already applied (check its sequence number against the store's last applied sequence).
2. Inspect the persisted catalog store (influxdb3 data directory) for corruption or stale sequence state; restore from a known-good snapshot if corrupted.
3. Ensure only one writer produces ordered batches at a time; check for duplicate nodes pointing at the same catalog store.
4. Upgrade influxdb3 to the latest patch release; known issues in batch application have been fixed in later versions.
5. File an issue with the batch contents if the state appears consistent — this panic indicates an internal invariant break.

// before replaying an ordered batch
let last_seq = store.last_applied_sequence();
if batch.sequence_number() <= last_seq {
    return Err("batch already applied");
}
if batch.batch().is_empty() {
    return Err("empty batch");
}

fn batch_has_changes(batch: &CatalogBatch) -> bool {
    !batch.batch().is_empty()
}

match catalog.apply_ordered_batch(&batch) {
    Ok(applied) => proceed(applied),
    Err(e) => log::error!("ordered batch application failed: {e}"),
}
// Note: the expect() panics — treat any panic in this path as fatal and restart from a consistent snapshot.

When it happens

Trigger: Applying an ordered catalog batch whose underlying changes produce no mutations (e.g. replaying an already-applied batch, an empty batch slipping through sequence handling, or a batch whose writes were deduplicated away).

Common situations: Catalog replay/bootstrap against a persisted store where sequence numbers and stored state diverge; software upgrades changing batch persistence formats; concurrent writers corrupting the ordered batch queue.
