Will a call to SQL cause my multi threading app to bottleneck?

The way I would approach this is to have a Queue which you add the stuff you're going to parse and persist and then have that serviced by a pool of threads, or even just one thread, it depends on the expected throughput. The key here is the queue is serviced as soon as possible, but if there is a backlog it doesn't affect adding more items.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
