  1 | = Data Streaming with Kafka and Quarkus
  2 | 
  3 | ==== Problem Statement
  4 | 
  5 | The problem statement is described here
  6 | https://developers.redhat.com/blog/2020/09/28/build-a-data-streaming-pipeline-using-kafka-streams-and-quarkus/
  7 | 
  8 | ==== Pre-requisite
  9 | 
 10 | 1. Make sure you have docker and kakfa cli available in your laptop/env
 11 | 
 12 | ==== Step 1: Run Kafka Cluster
 13 | 
 14 | Make sure you have docker installed on your laptop. Run following command to start a kafka cluster
 15 | ----
 16 | $ git clone https://github.com/wurstmeister/kafka-docker.git
 17 | $ cd kafka-docker
 18 | ----
 19 | 
 20 | open docker-compose-single-broker.yml and change the following line 
 21 | KAFKA_ADVERTISED_HOST_NAME: 192.168.99.100
 22 | 
 23 | to 
 24 | 
 25 | KAFKA_ADVERTISED_HOST_NAME: localhost
 26 | 
 27 | ----
 28 | $ docker-compose -f docker-compose-single-broker.yml up -d
 29 | ----
 30 | 
 31 | ==== Step 2: Create Kafka Topics
 32 | 
 33 | We will now create left-stream-topic, right-stream-topic, stream-stream-outerjoin, processed-topic topics using kafka cli
 34 | 
 35 | ----
 36 | $ cd <folder location where kafka cli binaries are located>
 37 | $ ./kafka-topics.sh --create --bootstrap-server localhost:9092 --replication-factor 1 --partitions 1 --topic left-stream-topic
 38 | $ ./kafka-topics.sh --create --bootstrap-server localhost:9092 --replication-factor 1 --partitions 1 --topic right-stream-topic
 39 | $ ./kafka-topics.sh --create --bootstrap-server localhost:9092 --replication-factor 1 --partitions 1 --topic stream-stream-outerjoin
 40 | $ ./kafka-topics.sh --create --bootstrap-server localhost:9092 --replication-factor 1 --partitions 1 --topic processed-topic
 41 | 
 42 | ----
 43 | 
 44 | ==== Step 3: Run the streaming application
 45 | 
 46 | ----
 47 | $ git clone https://github.com/kgshukla/data-streaming-kafka-quarkus.git
 48 | $ cd data-streaming-kafka-quarkus/quarkus-kafka-streaming
 49 | 
 50 | # start the application in dev mode. You could also package the application as a jar file and start using 'java -jar' command
 51 | $ ./mvnw compile quarkus:dev
 52 | 
 53 | ----
 54 | open a new terminal and initialize the application. This step wasn't needed if the application was defined with ApplicationScoped notation
 55 | 
 56 | ----
 57 | $ curl localhost:8080/startstream
 58 | ----
 59 | 
 60 | ==== Step 4: Run the producer application
 61 | 
 62 | Open a new terminal and run the following commands
 63 | ----
 64 | $ cd data-streaming-kafka-quarkus/quarkus-kafka-producer
 65 | 
 66 | $ ./mvnw compile quarkus:dev
 67 | 
 68 | ----
 69 | 
 70 | ==== Step 5: Watch the processed-topic topic
 71 | 
 72 | ----
 73 | $ cd <folder location where kafka cli binaries are located>
 74 | $ ./kafka-console-consumer.sh --bootstrap-server localhost:9092 --topic processed-topic --property print.key=true --property print.timestamp=true
 75 | ----
 76 | 
 77 | ==== Step 6: Simulate various use cases
 78 | 
 79 | Use case 1 - Send few records to left-stream-topic, right-stream-topic topics
 80 | 
 81 | Couple of records will be missing in left-stream-topic. You will notice that punctuator will process those records which have been put into state store.
 82 | 
 83 | ----
 84 | $ curl localhost:8082/sendfewrecords
 85 | ----
 86 | 
 87 | Use case 2 - Send one record to left-stream-topic only
 88 | 
 89 | You will notice that punctuator will process those records which have been put into state store.
 90 | 
 91 | ----
 92 | $ curl localhost:8082/sendoneleftrecord
 93 | 
 94 | # to see records that are present in the state store and not yet processed
 95 | $ curl localhost:8080/storedata
 96 | ----
 97 | 
 98 | Use case 3 - send 100000 records to both left-stream-topic, right-stream-topic topics
 99 | 
100 | ----
101 | $ curl localhost:8082/sendmanyrecords
102 | ----
103 |

 1 | # quarkus-kafka-producer project
 2 | 
 3 | This project uses Quarkus, the Supersonic Subatomic Java Framework.
 4 | 
 5 | If you want to learn more about Quarkus, please visit its website: https://quarkus.io/ .
 6 | 
 7 | ## Running the application in dev mode
 8 | 
 9 | You can run your application in dev mode that enables live coding using:
10 | ```
11 | ./mvnw quarkus:dev
12 | ```
13 | 
14 | ## Packaging and running the application
15 | 
16 | The application can be packaged using `./mvnw package`.
17 | It produces the `quarkus-kafka-producer-1.0.0-SNAPSHOT-runner.jar` file in the `/target` directory.
18 | Be aware that it’s not an _über-jar_ as the dependencies are copied into the `target/lib` directory.
19 | 
20 | The application is now runnable using `java -jar target/quarkus-kafka-producer-1.0.0-SNAPSHOT-runner.jar`.
21 | 
22 | ## Creating a native executable
23 | 
24 | You can create a native executable using: `./mvnw package -Pnative`.
25 | 
26 | Or, if you don't have GraalVM installed, you can run the native executable build in a container using: `./mvnw package -Pnative -Dquarkus.native.container-build=true`.
27 | 
28 | You can then execute your native executable with: `./target/quarkus-kafka-producer-1.0.0-SNAPSHOT-runner`
29 | 
30 | If you want to learn more about building native executables, please consult https://quarkus.io/guides/building-native-image.

 1 | # quarkus-kafka-streaming project
 2 | 
 3 | This project uses Quarkus, the Supersonic Subatomic Java Framework.
 4 | 
 5 | If you want to learn more about Quarkus, please visit its website: https://quarkus.io/ .
 6 | 
 7 | ## Running the application in dev mode
 8 | 
 9 | You can run your application in dev mode that enables live coding using:
10 | ```
11 | ./mvnw quarkus:dev
12 | ```
13 | 
14 | ## Packaging and running the application
15 | 
16 | The application can be packaged using `./mvnw package`.
17 | It produces the `quarkus-kafka-streaming-1.0.0-SNAPSHOT-runner.jar` file in the `/target` directory.
18 | Be aware that it’s not an _über-jar_ as the dependencies are copied into the `target/lib` directory.
19 | 
20 | The application is now runnable using `java -jar target/quarkus-kafka-streaming-1.0.0-SNAPSHOT-runner.jar`.
21 | 
22 | ## Creating a native executable
23 | 
24 | You can create a native executable using: `./mvnw package -Pnative`.
25 | 
26 | Or, if you don't have GraalVM installed, you can run the native executable build in a container using: `./mvnw package -Pnative -Dquarkus.native.container-build=true`.
27 | 
28 | You can then execute your native executable with: `./target/quarkus-kafka-streaming-1.0.0-SNAPSHOT-runner`
29 | 
30 | If you want to learn more about building native executables, please consult https://quarkus.io/guides/building-native-image.
