What is Kafka
Apache Kafka is publish-subscribe based fault tolerant messaging system. It is fast, scalable and distributed by design.
It was initially thought of as a message queue and open-sourced by LinkedIn in 2011. Its community evolved Kafka to provide key capabilities:
Publish and Subscribe to streams of records, like a message queue.
Storage system so messages can be consumed asynchronously. Kafka writes data to a scalable disk structure and replicates for fault-tolerance. Producers can wait for write acknowledgments.
Stream processing with Kafka Streams API, enables complex aggregations or joins of input streams onto an output stream of processed data.
Traditional messaging models are queue and publish-subscribe. In a queue, each record goes to one consumer. In publish-subscribe, the record is received by all consumers.
Pros of Kafka
Loose coupling - Neither service knows about each other regarding data update matters.
Durability - Guarantees that the message will be delivered even if the consumer service is down. Whenever the consumer gets up again, all messages will be there.
Scalability - Since the messages get stored in a bucket, there is no need to wait for responses. We create asynchronous communication between all services.
Flexibility - The sender of a message has no idea who is going to consume it. Meaning you can easily add new consumers (new functionality) with less work.
Cons of Kafka
Semantics - The developer needs to have a deep understanding of the message flow as its strict requirements. Complex fallback approaches may take place.
Message Visibility - You must track all those messages to allow you to debug whenever a problem occurs. Correlation IDs may be an option.

Please upload the videos of terminology and then we can move towards implementations.

[@CodeDecode]

Sure Prafull thanks for helping in deciding priorities 👍🙂

[@sidhanshuraghuvanshi1]

Important Update: we can use pub-sub system in ActiveMQ as well; I have worked on this. Kafka can handle large sets of data, so when we have real time or large sets of data better solution is to use Kafka. Btw thanks a lot for all the videos. Great videos.

[@sandiyr1989]

yes you r right...i was very confused about that...

[@gopishettymahindra2713]

Hi Madam , if the messages are not deleted and storing in disk, then how consumer came to know whether that message is already read or unread

[@kalekar100]

Thanks!

[@CodeDecode]

🙂

[@kumarabhishek1064]

Hi, I have seen code snippets where REST API calls are used to make asynchronous calls but you have clearly said that it falls under synchronous call.
can you clarify on this?

[@CodeDecode]

Can we send a rest api request and forget about it? Async means u send n forget about it even if receiving end is down, no issues. That's async communication

[@padmalankipalli593]

Pls share the terminology and architecture. Thank you @codedecode team

[@CodeDecode]

Sure Padma👍🙂

[@padmalankipalli593]

Thank you for uploading sample demo. Waiting for architecture

I want all terminology & details understanding for kafka

[@CodeDecode]

Sure Dhananjay🙂👍

[@hackstreet781]

I have one doubt, You are saying Rabbit MQ is a point to point message broker but in RabbitMQ, there is TOPIC exchange as well that supports one to many messaging. So, why are we calling Rabbit MQ is point to point and not topic based ?

[@CodeDecode]

Rabbit mq is both. You can use them as both but most use cases comes around with point to point. Kafka is better for pub sub models

[@pradeepkumar-qu1gc]

Hi, Can you provide these PPT's to us?
