colstore.update

colstore.update(path, *, statistics=False)[source]

Open an existing file for append.

The schema is loaded from the existing manifest; every write() must match it exactly. Orphan bytes from a crashed prior writer (if any) are truncated on open. Raises FileNotFoundError if the file does not exist. statistics=True keeps the per-column statistics current as records are appended; pass it on each update to keep them (off by default).

Parameters:
Return type:
