java - Searching strategy in an infinte list -

-

I am listening to a third party web-service, when the service begins, I get a stream of goods That is what I am receiving. I have to find a specific object within the amount of time and some processing should be done if the object has been found or an error has been placed in any of the following situations:

  1. Web service stops And I object is not found
  2. My timer has expired
  3. Any other wrong status

I am wondering what is the best way to search for the object that I am searching for an infinite list and the items in which they appear in the list are predicted Can not be done?

If the order can not be estimated, then there is no better than simply obtaining each object No way

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'
