Fetures Post Monitoring query progress LinkedIn Post On Phone

Story Instagram Template PSD Since queries can take a while to complete, it is useful to be able to monitor their progress (e.g. to log the query ID and its state) while they are still running, rather than only after all rows have been fetched. Pass a stats_callback to Connection.cursor() to have it invoked with the query stats every time the client polls the coordinator: Example Of A Bad Product Instagram Post

def log_progress(stats): print(stats["queryId"], stats.get("state")) cur = conn.cursor(stats_callback=log_progress) cur.execute("SELECT * FROM system.runtime.nodes") rows = cur.fetchall()

First Instagram Post The callback fires once as soon as the query is submitted, so the query ID and initial state are available while the query is still running, and again after every subsequent poll of the coordinator. Each invocation receives a copy of the query's current stats dictionary (the same dictionary returned by Cursor.stats), so mutating it has no effect on the client. Any exception raised by the callback propagates to the caller of execute()/fetch(). Stop Please Read Sign
