-- Starts a SQL transaction.
--
-- A transaction can run for a maximum of 24 hours. A transaction is
-- terminated and rolled back automatically after 24 hours.
--
-- A transaction times out if no calls use its transaction ID in three
-- minutes. If a transaction times out before it\'s committed, it\'s rolled
-- back automatically.
--
-- DDL statements inside a transaction cause an implicit commit. We
-- recommend that you run each DDL statement in a separate
-- @ExecuteStatement@ call with @continueAfterTimeout@ enabled.
