Composing Event Streams: SnakeGame$

Diving deeper into building user interfaces you may encounter a few challenges in how to manage asynchronicity between features and events, the y may occur in a given point in time.

So we will be recreating the snake game using event composition with Observables.

warning: this is not a introduction to Observables neither to event composition and it may have a lot of mistakes which you could/ may point them out and I will be more than happy to take into account as a feedback.

There are plenty async primitives that empower us to model our application from callbacks, promises, to all way around to Observables. I chose Observables because it makes the data flow natural and fluid. In my so adorable opinion, I think, they are the best and funniest async primitive to composing events on Javascript.

TLTR:stops this madness and show me the code!

For starters we will modelling user interaction as a stream. So every time the user press a key down the snake will reacts accordingly, in other words we could map keys over updates in the snake position. We will be listen for ‘ArrowUp’, ‘ArrowDown’, ‘ArrowLeft’, and ‘ArrowRight’ keys but you may use another set of keys combination.

Stateful stream processing with Apache Flink(part 1): An introduction

Apache Flink, a 4th generation Big Data processing framework provides robust **stateful stream processing capabilitie**s. So, in a few parts of the blogs, we will learn what is Stateful stream processing. And how we can use Flink to write a stateful streaming application.

What is stateful stream processing?

In general, stateful stream processing is an application design pattern for processing an unbounded stream of events. Stateful stream processing means a** “State”** is shared between events(stream entities). And therefore past events can influence the way the current events are processed.

Let’s try to understand it with a real-world scenario. Suppose we have a system that is responsible for generating a report. It comprising the total number of vehicles passed from a toll Plaza per hour/day. To achieve it, we will save the count of the vehicles passed from the toll plaza within one hour. That count will be used to accumulate it with the further next hour’s count to find the total number of vehicles passed from toll Plaza within 24 hours. Here we are saving or storing a count and it is nothing but the “State” of the application.

Might be it seems very simple, but in a distributed system it is very hard to achieve stateful stream processing. Stateful stream processing is much more difficult to scale up because we need different workers to share the state. Flink does provide ease of use, high efficiency, and high reliability for the**_ state management_** in a distributed environment.

Spark Structured Streaming – Stateful Streaming

Welcome back folks to this blog series of Spark Structured Streaming. This blog is the continuation of the earlier blog “Internals of Structured Streaming“. And this blog pertains to Stateful Streaming in Spark Structured Streaming. So let’s get started.

Let’s start from the very basic understanding of what is Stateful Stream Processing. But to understand that, let’s first understand what Stateless Stream Processing is.

In my previous blogs of this series, I’ve discussed Stateless Stream Processing.
