The reason that we don't make every little thing atomic by default is, that there's a performance cost and for many issues Really don't really want thread protection. A couple of areas of our code will need it and for people couple of elements, we have to compose our code in a very thread-Safe and sound way applying locks, mutex or synchronization.
atomic concept, historical philosophical speculation that each one items could be accounted for by innumerable combinations of hard, small, indivisible particles (called atoms) of assorted measurements but of precisely the same standard content; or the modern scientific idea of make any difference In keeping with which the chemical things that Merge to type the great a number of substances consist by themselves of aggregations of similar subunits (atoms) possessing nuclear and electron substructure attribute of every element.

These kinds of denormalizations are quite common, because it is quite tricky to draw the road and what is atomic and what's not. With regards to the application, a multi-portion column could really well be the ideal Remedy occasionally. It can be significantly less structured, but more simple.
