Instructor: So how does S3 consistency work?
Well, as of December 2020, now there is strong consistency
on Amazon S3 for all operations
and this is something that was different from before.
So just remember that now it's very simple.
All operations are strongly consistent.
What does that mean?
Well, that means that after you write a new object,
so after you do a successful write
and you write a new object into Amazon S3
or after you overwrite or delete an existing object,
okay, after you do any of these operations,
any time you do a read, okay, read after write,
you're going to receive the object that was just written.
And they used to be not the case, but now it is.
And anytime you do a list,
then you're going to also see that item into the list.
So it is something new for Amazon S3 as of December 2020
so just remember that now Amazon S3 is strongly consistent
so anytime you do a write, then you do a read after,
the read is going to give you the same results
of what you just uploaded or what you just wrote,
so this is perfect.
And this is available to you
at no additional cost without any performance impact.
So that's it, just a very short one on this,
but I will see you in the next lecture.
