Google App Engine Query Limit and Timeout

I am using App Engine to build a site, and now I worry about the 30 seconds Time per request limit.

For example, I have more than 10,000 members or even more, and I do the following:

# class Member(db.Model): ...
# Start a query 
result = Member.all().filter('username =','example').filter('password = ','123456').get()
#Will this time out?
result = Member.all().order('joindate').fetch(10)
#Will this time out?

I wonder, will these queries work without Timeout? I am afraid the .all().filter().order() will timeout.

Is there some more secure way to do that when the number of members are too large?

By the way, will this 30 secs per request limit apply when I upload a video to the app engine Blobstore? The max single file size for Blobstore is 2GB, and if I upload via an HTML form, it may take hours. Will the 30 secs per request limit apply?

Thanks a lot!

To be short:

  1. the first two fetch query will be completed within 1 second. Actually, it should be completed within several hundreds of ms or dozens of ms.

  2. the '.all().filter().order()' has not tried to fetch any data at all, so don't worry about the time.
