Invalid table ID

Error message

Invalid table ID: {0}

What it means

PathError::InvalidTableId occurs when the table identifier component of a storage path fails validation — the component is not a well-formed table ID. Like InvalidDbId it includes the offending value and prevents malformed keys from being treated as table paths.

Solutions

Inspect the invalid table segment from the error and fix or delete the offending object
Avoid manual edits to object-store keys; recreate tables through the API
Confirm both producer and consumer code use the same table-ID format (numeric vs name)
Restore affected prefixes from a known-good backup if the store was corrupted

Example fix

// before
// key: databases/12/tables/cpu/1.parquet (name 'cpu' where id expected)
// after
// key: databases/12/tables/42/1.parquet (valid table id)

Defensive patterns

Strategy: validation

Validate before calling

fn valid_table_id(seg: &str) -> bool {
    seg.parse::<u64>().map(|id| id > 0).unwrap_or(false)
}

Type guard

fn is_valid_table_segment(s: &str) -> bool {
    s.parse::<u64>().is_ok()
}

Try / catch

match parse_table_path(key) {
    Err(PathError::InvalidTableId(bad)) => {
        log::warn!("invalid table id {:?} in {} — quarantining", bad, key);
        quarantine(key);
        continue;
    }
    Ok(p) => handle(p),
}

Prevention

Always obtain table IDs from the catalog rather than table names
Avoid manual copying/renaming of table directories in object storage
Scan with skip-and-log semantics so one bad key doesn't halt recovery
Keep versions consistent so table path layout matches between components

When it happens

Trigger: Parsing object-store keys where the table segment is empty, non-numeric, or otherwise fails the table-ID validator, typically during listing/recovery scans of table data files.

Common situations: Manual object-store manipulation (renamed or copied directories); files from incompatible versions; corruption or truncation of keys during failed uploads/restores.
