With Amazon EC2 and S3, is it possible to do both transfers to AND FROM S3 through EC2, making it free? -

-

This can be a silly question, but in the same area as the transit between EC2 and S3 Is independent within, why it is not possible to transmit all transfers through S3 and EC2 and transfer is completely free?

In particular, I'm looking at Heroko, which is Ruby on the hosting service of Rail 2 running ES2, where bandwidth is free, they upload uploads first, and especially note They are free for the S3 when displayed through Heroku. However, I was wondering why a single move would not work in reverse, as if any requested file is flown through EC2?

If this is possible, will it be difficult to setup? I can not find any ideas of this concept on Google.

The transfer is free, but it still spends money to store the data on the S3. .. or am I forgetting something?

oracle - The fastest way to check if some records in a database table? -

-
I have a big table to work with. I have to see that there are some records whose parent_id is equal to my passing value. Currently I do this by implementing "my_table using select count (*) where parent_id =: id"; If the result> 0, it means that they exist. Because this is a very large table, and I do not care what the actual number of records present, I just want to know if it exists, so I think count (*) Bit is disabled. How do I apply this requirement most quickly? I'm using Oracle 10. # Tips for Hibernation & amp; Tricks It suggests writing in such a way: Integer number = (integer) session .createQuery ("Select Count (*) to ...."). UniqueResult (); I do not know what is the magic of the unique rule? Why does it fast? To compare, select "1 from mytable where parent_id = passId and rowrum", which is more efficient? If you are not interested in the number of records, then there is an EXISTS query one: Select 'y'
