How git stores snapshot -

-

GET, as stated, deltas but not snapshot . Now I have a very specific question.

Let's say I have a code and it's master 

  #include

And then I'll just change it to an additional line and add another reverse call to the last line of the last 

  # Include & lt; Iostream & gt; using namespace std; Zero swap (four * a, int i, et j) {int t = a [ii]; A [i] = a [ja]; A [j] = t; } Zero Reverse (four * A, int size) {for (int i = 0; i & lt; size / 2; i ++) swap (a, i, size-1i); } Int main () {int n; Cin & gt; & Gt; N; Four a [n]; Int k; Cin & gt; & Gt; K; (Int i = 0; i & lt; n; i ++) cin & gt; & Gt; A [i]; Reverse (A, N-Kashmir); Reverse (A + N-Kashmir, Kashmir); Reverse (A, n); For (int i = 0; i & lt; n; i ++) COAT & LT; & Lt; A [i]; Cout & lt; & Lt; Endl; }

And then I commit it to the same branch ( master ).

Now my question is, what does GIT Store really do not answer me? Snapshot I want to know whether the snapshot means technically what it means that it stores the entire file as it is, it will actually be disabled or it actually stores delta but if That's why, then why do they call them a snapshot?

A new blob for the modified file modified and then a new revised directory For trees and then a new commit and then put these three (and other objects created) in the object database.

Blob for a file is a binary object that contains the object type (blob), object size, and actual content. So, yes, if you modify only one row in a file, then GIT will store the whole thing twice, not only the difference

Normally, the disk for git speed and from that perspective It is not "disabled" by any means, in any way.

Although this method of storage (called called objects) is not particularly suited for transport, therefore, git has the ability to pack these loose items in the packed file and an index. The packing process will identify the small difference object, put them together and compile the delta into a packed file. They are more compact and more efficient than the transport point of view.

It is best that I can say in the words of your question. The link I commented on describes what happens when you store something in detail. If you have specific questions, please ask more precisely.

I have a requirement whenever I run my own kettle, dynamically took database connection parameters from an excel source Every run should go. I have an Excel column names: hostname, username, database, password. I want to pass these connection parameters to my table input stage dynamically whenever it runs the job. This is what I was trying to do. You can get it Connection parameters from the DB reading source (for example Excel or a CSV file in my example) < / Li> Store the parameters in the variable Using the variable in your connection's settings. Setting Variables Create another conversion for (you can not do it in the same conversion Uses): set variables element variable: The element that reads / writes your data creates a new connection and sets the connection parameter using $ {variable name_} Note that you will need to type in the field field in the field $ {password} Also keep in mind that this can be a security problem as the

I am trying to implement a screen-scraps application that opens a URL in which a parameter changes as it is for a loop: var data = [ '100', '101', '102', '103', '104']; (Var indexA = 0; indexA & lt; data.length; indexA ++) for {Phantom Generation ({'port': freeport}, function (pH) {ph.create page (function (page) {page.open ("http: //...++ data [index B] +" ...

Data is verified in scrap HTML and from index to array Matches. So in page 101 I scrap '101 and retrieve' and pu
