Can we schedule StackDriver Logging to export log?

I am new to Google Cloud StackDriver Logging and as per this documentation StackDriver stores the Data Access audit logs for 30 days. Also mentioned on the same page, that Size of a log entry is limited to 100KB.
I am aware of the fact that the logs can be exported Google Cloud Storage using Cloud SDK as well as using Logging Libraries in many languages (we prefer Python).
I have two questions related to the exporting the logs, which are:

1. Is there any way in StackDriver to schedule something similar to a task or cronjob that keeps exporting the Logs in the Google Cloud storage automatically after a fixed interval of time?
2. What happens to the log entries which are larger than 100KB. I assume they get truncated. Is my assumption correct? If yes, is there any way in which we can export/view the full(which is not at all truncated) Log entry?

Stackdriver supports exporting log data via sinks. There is no schedule that you can set as everything is automatic. Basically, the data is exported as soon as possible and you have no control over the amount exported at each sink or the delay between exports. I have never found this to be an issue. Logging, by design, is not to be used as a real-time system. The closest is to sink to PubSub which has a couple of second delay (based upon my experience).

There are two methods to export data from Stackdriver:

1. Create an export sink. Supported destinations are BigQuery, Cloud Storage and PubSub. The log entries will be written to the destination automatically. You can then use tools to process the exported entries. This is the recommended method.
2. Write your own code in Python, Java, etc. to read the log entries and do what you want with them. Scheduling is up to you. This method is manual and requires your management of schedule and destination.

What happens to the log entries which are larger than 100KB. I assume they get truncated. Is my assumption correct? If yes, is there any way in which we can export/view the full(which is not at all truncated) Log entry?

Entries that exceed the max size of an entry cannot be written to Stackdriver. The API call that attempts to create the entry will fail with an error message similar to (Python error message):

400 Log entry with size 113.7K exceeds maximum size of 110.0K

This means that entries that are too large will be discarded unless the writer has logic to handle this case.
