catalog update error

Error message

catalog update error: {0}

What it means

This error wraps a CatalogError that occurred while updating the InfluxDB 3 catalog (the persisted metadata describing databases, tables, and columns). The write buffer raises it whenever an incoming write requires a catalog mutation (e.g. creating a database/table or adding a column) and the catalog layer returns an error. It is a transparent conversion (`#[from]`), so the underlying CatalogError is preserved as the source.

Solutions

1. Inspect the inner CatalogError (the `{0}` payload) to find the root cause
2. Check that the catalog persister backend (object store, etc.) is reachable and correctly configured
3. Retry the write; transient races during implicit table creation usually resolve on retry
4. Verify all nodes run the same influxdb3 version so catalog schemas match

Example fix

// before: opaque handling
match write_result { Err(e) => panic!("write failed: {e}"), ... }
// after: match the variant and surface the inner catalog error
match write_result {
    Err(WriteBufferError::CatalogUpdateError(catalog_err)) => {
        log::error!("catalog update failed: {catalog_err}");
        // fall back / retry with the specific catalog error context
    }
    Err(e) => return Err(e.into()),
    Ok(v) => v,
}

// ensure schema-compatible write: pre-check column types via catalog
let table = catalog.table(db, table_name)?;
for col in incoming_columns {
    if let Some(existing) = table.column(&col.name) {
        assert_eq!(existing.data_type, col.data_type, "type conflict on {}", col.name);
    }
}

match result {
    Err(WriteBufferError::CatalogUpdateError(e)) => retry_with_backoff(|| write_lp(db, lp, false)),
    other => other?,
}

When it happens

Trigger: Writing to influxdb3 via the write buffer when the request requires a catalog update: creating a new database or table implicitly, adding a new column to an existing table, or any DDL-time catalog persist operation that fails (e.g. the persister/backend rejects the update).

Common situations: Racing concurrent writes that both try to create the same table/column; catalog persistence backend (object store / persister) unavailable or misconfigured; corrupted or out-of-sync catalog state after a crash or version upgrade.
