## Problem Three files in the Google provider use `.pop(0)` and `.insert(0, ...)` for cursor row buffering. Both operations are **O(n)** on Python lists. ## Solution Switch to `collections.deque` with `.popleft()` and `.appendleft()` for **O(1)** front operations. ## Changes | File | Pattern | |------|---------| | `hooks/bigquery.py` | `BigQueryCursor.buffer` — row fetch buffer | | `transfers/presto_to_gcs.py` | `_PrestoHTTPCursorAdapter.rows` — row peek/fetch buffer | | `transfers/trino_to_gcs.py` | `_TrinoCursorAdapter.rows` — row peek/fetch buffer | All existing `.append()`, truthiness checks, and iteration work identically on deque. -- This is an automated message from the Apache Git Service.
