海外TECH	DEV Community	Introduction to Key Apache KafkaⓇ Concepts	https://dev.to/cerchie/introduction-to-key-apache-kafka-concepts-2mbp	Introduction to Key Apache KafkaⓇConcepts IntroductionLast week I started a brand new role Developer Advocate at Confluent So far I ve been gladdened by stepping fully into an area of tech that satisfies my teaching heart I ve also felt supported by my new teammates I m new to the Kafka scene with a background in JavaScript and GraphQL In order to help onboard me smoothly my teammates are meeting with me frequently checking in on my progress they even reviewed this article and are helping me select material from Confluent s abundance of resources to learn Kafka My first step in my learning journey was this course on Kafka I took notes throughout the course which broke Kafka down to its core concepts I ll share the synthesis of those notes below in hopes that if you re coming from a similar background you ll find it useful What is Kafka According to its website Kafka is a distributed event streaming platform Well what does that mean to me a mostly JavaScript developer with a background in web development and GraphQL My usual approach to learning entirely new concepts is to take a back to square one approach and understand some fundamental vocabulary first Much like you might estimate the result of a math problem before tackling its execution e g estimating that the sum of will not be above I like to situate myself with respect to the context of a new skill before executing it The following paragraphs set the context of Kafka by defining and illustrating key concepts What is an Event So a distributed event streaming platform The key piece of terminology here is event Before I took the course I understood an event as a thing that happens which still holds up within the context of Kafka In Kafka events are things that happen and the representation of these things are recorded by machines Let s take for example the event of a credit card transaction The event is composed of a notification and the event s state To implement this event in Kafka you d need certain pieces of information including a key value timestamp and optional metadata headers So you d have something like Key “Credit Card Payment Value “Paid for a ham sandwich Timestamp “ Kafka serializes these pairs into a structured format like JSON Avro or Protobuf By default event sizes in Kafka are MB What is a Topic At a high level topics are ways of organizing events They are programmatic logs of events as opposed to application logs You can see this article by Jay Kreps to learn more about the difference Logs have noteworthy aspects They are append only New messages are only applied to the end of a log They can t be insertedーunlike with a different structure like a graph You can t change events in a log This was important for me to wrap my head around since I was coming from a GraphQL background and you can certainly mutate data objects using GraphQL Access to logs is sequential from a given offset so they re read by picking an arbitrary offset and scanning What is a Cluster Ok cool but where are these events and logs kept so I can access them Are they hosted somewhere Kafka s storage layer is a cluster of things called brokers Brokers are servers that handle things like write and read requests to partitions as well as replication Which brings us to What is a Partition Logs are hosted and replicated across a cluster of machines rather than clogging up one machine 🪠 Partitions make this possible They take a single topic log and break it up into multiple logs Now how are messages written to partitions If the messages are keyless they ll be assigned one after the other until the last partition is reached in which case the process starts from the top Messages which have keys are assigned to partitions holding messages with the same keys Kafka does this by hashing the key and using a mod function If you want to take a deep dive into partitions you can read this blog post by Ricardo Ferreira that examines them from the perspective of both developers and data ops What is a Producer The producer sends the key value pairs to the clusters managing the interaction between brokers over a network Incidentally producers are also responsible for message assignment to partitions You can view a producer instance created with the Confluent client in Python in the Confluent Developer website Parse the configuration See config parser ConfigParser config parser read file args config file config dict config parser default Create Producer instance producer Producer config What is a Consumer A Kafka consumer reads the data from the stream Many independent consumers can read from one topic When a message is read it is not deleted Consumers handle scaling automatically You can see how to instantiate a consumer instance in Node JS on the Confluent Developer Getting Started tutorial function createConsumer config onData const consumer new Kafka KafkaConsumer createConfigMap config auto offset reset earliest return new Promise resolve reject gt consumer on ready gt resolve consumer on data onData consumer connect ConclusionLet s go back to the original definition of Kafka a distributed event streaming platform We now know that an event is a representation of a thing that happens expressed in a key value pair These events are organized by topics logs which are partitioned by producers and read by consumers The platform is a cluster of brokers that enable replication and fault tolerance Together this system is Kafka The system arises from the viewpoint that data is not static that it s everywhere flowing and interconnected That doesn t mean you can t integrate streaming data with classic data sources like databases and REST APIs or that you can t filter transform and manage it But that s a topic for another day	2022-10-11 20:37:58
