code: def eventually(

  ):
      """
      Wait a given amount of time for a condition to pass, else fail with an error.
      This is a helper utility for PySpark tests.
  
      Parameters
      ----------
      condition : function
          Function that checks for termination conditions. condition() can return:
              - True or None: Conditions met. Return without error.
              - other value: Conditions not met yet. Continue. Upon timeout,
                include last such value in error message.
                Note that this method may be called at any time during
                streaming execution (e.g., even before any results
                have been created).
      timeout : int
          Number of seconds to wait.  Default 30 seconds.
      catch_assertions : bool
          If False (default), do not catch AssertionErrors.
          If True, catch AssertionErrors; continue, but save
          error to throw upon timeout.
