If I want to fetch million rows in hibernate, how would it work? Will hibernate crash? How can I optimize that.
If you read one/write one it will probably work fine. Are you sure this the way you want to read 1,000,000 rows? It will likely take a while.
If you want all the objects to be in memory at the same time, you might well be challenged.
You can optimize it best, probably, by finding a different way. For example, you can dump from the database using database tools much more quickly than reading with hibernate.
You can select sums, maxes, and counts in the database without returning a million rows over the network.
What are you trying to accomplish, exactly?
