table index error

Error message

table index error: {0}

What it means

PersisterError::TableIndexPathError wraps a crate::paths::PathError produced while building or parsing a structured object-store path (SnapshotInfoFilePath / TableIndexPath / TableIndexSnapshotPath) during snapshot persistence or load. The path helpers validate that identifiers (db, table, snapshot sequence) are well-formed before constructing the object-store key. It surfaces from the persister whenever an invalid or malformed path component is used to address snapshot/table-index files.

Solutions

1. Inspect the #[source] PathError to identify which path component failed validation
2. List the object store prefix and verify snapshot/index files follow the expected canonical naming scheme
3. Re-check the database and table identifiers being passed to the persister for emptiness or invalid characters
4. Delete or re-persist the offending snapshot files so paths are regenerated by the writer

Example fix

// before: manually renamed snapshot file
snapshots/0000012.json  // trailing content changed, name truncated
// after
snapshots/0000012.persisted_snapshot.json  // canonical Persister snapshot filename

fn valid_path_component(s: &str) -> bool { !s.is_empty() && !s.contains('/') && s.chars().all(|c| c.is_ascii_alphanumeric() || c=='-' || c=='_') }
// validate db/table names before handing them to persister APIs

fn is_table_index_path_error(e: &PersisterError) -> Option<&crate::paths::PathError> {
    if let PersisterError::TableIndexPathError(pe) = e { Some(pe) } else { None }
}

match persister_result {
    Err(PersisterError::TableIndexPathError(pe)) => log::error("bad path component: {pe}"),
    other => other?,
}

When it happens

Trigger: Calling Persister methods (persist snapshot, load snapshot, write/load table index) where the path constructor crate::paths::* receives an identifier or parsed filename component that fails PathError validation, e.g. an empty table name or a snapshot path whose sequence-number component cannot be parsed.

Common situations: Manually renaming or crafting snapshot files in the object store bucket with non-canonical names; restoring data written by a different InfluxDB3 version whose filename layout changed; database/table names with characters that do not round-trip through the path encoding.
