CAP Theorem

CAP Theorem talks about tradoffs of disturbed systems

Here
C - Consistency (Every read request to the distributed system should return same result irrespective of whichever node we are reading from)
A - Availability (The system should respond to any request made to it irrespective of any node is failed or not)
P - Partition Tolerance (The system continues to respond/operate even though there is a network breakdown/partition between the nodes)

Before Diving into CAP theorem here is some background knowledge you should know

Distributed System : Data Stored in multiple servers instead of one(like we do when we apply horizontal scaling)

Why distributed systems?
> Spread Workload among multiple servers
> Can handle more number of requesss
> Improves overall performance

In distributed system we replicate same data across multiple systems to get the above benifits.

Server/s are called a node here.

Now let's talk about the CAP

Let's say there are there nodes X, Y and Z

Consistency says that whenever you read data from X, Y or Z they should return the same data and when you write then it should be propogated to other nodes to maintain consistency

Availability says that if B fails due to some hardware issue and go offline then A and C should still be working and should serve the requests

Partition Tolerance says if network partition happens on B and it can't communicate with A and C, then node B will still be serving requests even though it is not up to date with the data with other nodes(A and C) since it got a network partition.

CAP Theorem:
CAP Theorem states that in a distributed system, you can only guarantee two out of these three properties simultaneously. It's impossible to achieve all three

You can refer to the image below for clear understand about the statement once

Only the combination of
CA(Consistency-Availability), AP(Availability-Partition tolerance), CP(Consistency-Partition tolerance)
is possible

In distributed system there are very high chances of network partition so we should must handle P(partition tolerance).

So most of distributed systems choose either AP or CP because they can't afford network partition

What to choose between CP and AP
CP - if you can't afford inconsistent data then go for CP like banking, payment services where numbers are the most important thing

AP - if you can afford in consistent data but can't afford unavailability like social media can have slightly different likes, comments or views for different users but it can't have their apps down.

@ThedatagGuy which college is this?

[Tenma @tenma_dev]

@dextertwts Nice read

[Tenma @tenma_dev]

@pixperk will try this too

@zzzzshawn what is these bg called?, where can i find these cool bg, clean ui tho

[Tenma @tenma_dev]

how tf am I supposed to consolidate someone apart from saying it happens lmao

[Tenma @tenma_dev]

atp it's about minimizing things I don't know that I don't know ig

[Tenma @tenma_dev]

Tf is this ui of prajaakeeya

Seeing so many people's last btech last exam on my tl is kinda making me sad that I'll be posting the same by a year.
