Spring Cloud Stream Partitioning Sample
|
||||
========================================
|
||||
|
||||
This is a collection of applications that demonstrates how partitioning works in Spring Cloud Stream.
|
||||
|
||||
## Quick introduction
|
||||
|
||||
The producer used in the sample produces messages with text that has a length of 1, 2, 3 or 4.
|
||||
There is a configuration in the producer's application.yml file for `partition-key-expression` that uses the length of the payload minus 1 as the partition key expression to use.
|
||||
This value will be used by the binder for selecting the correct partition based on the total number of partitions configured on the destination at the broker.
|
||||
We use 4 partitions for this demo.
|
||||
|
||||
There is a common producer module called partitioning-producer and then there is a consumer for kafka and rabbit - partitioning-consumer-kafka and partitioning-consumer-rabbit respectively.
|
||||
Follow the instructions below to run the demo for Kafka or RabbitMQ.
|
||||
|
||||
## Running the sample for Kafka
|
||||
|
||||
The following instructions assume that you are running Kafka as a Docker image.
|
||||
|
||||
* `docker-compose up -d`
|
||||
|
||||
* cd partitioning-consumer-kafka
|
||||
|
||||
* `./mvnw clean package`
|
||||
|
||||
* `java -jar target/partitioning-consumer-kafka-0.0.1-SNAPSHOT.jar --server.port=9008`
|
||||
|
||||
On another termimal start another instance of the consumer.
|
||||
|
||||
* `java -jar target/partitioning-consumer-kafka-0.0.1-SNAPSHOT.jar --server.port=9009`
|
||||
|
||||
* cd ../partitioning-producer
|
||||
|
||||
* `./mvnw clean package`
|
||||
|
||||
* `java -jar target/partitioning-producer-0.0.1-SNAPSHOT.jar --server.port=9010`
|
||||
|
||||
Producer sends messages randomly that has string length of 1, 2, 3, or 4.
|
||||
Watch the consumer console logs and verify that the correct partitions are receiving the messages.
|
||||
The log message has the payload and partition information in it.
|
||||
|
||||
Once you are done testing, stop all the instances.
|
||||
|
||||
* `docker-compose down`
|
||||
|
||||
## Running the sample for Rabbit
|
||||
|
||||
The following instructions assume that you are running Rabbit as a Docker image.
|
||||
|
||||
Make sure that you are at the root directory of partitioning samples (partitioning-samples)
|
||||
|
||||
Rabbit partitioning demo is slightly different from Kafka.
|
||||
We need to spin up 4 consumers for each of the four partitions.
|
||||
|
||||
* `docker-compose -f docker-compose-rabbit.yml up -d`
|
||||
|
||||
* cd partitioning-consumer-rabbit
|
||||
|
||||
* `./mvnw clean package`
|
||||
|
||||
* `java -jar target/partitioning-consumer-rabbit-0.0.1-SNAPSHOT.jar --server.port=9005`
|
||||
|
||||
On another terminal start another instance of the consumer.
|
||||
|
||||
* `java -jar target/partitioning-consumer-rabbit-0.0.1-SNAPSHOT.jar --server.port=9006 --spring.cloud.stream.bindings.input.consumer.instanceIndex=1`
|
||||
|
||||
On another terminal start another instance of the consumer.
|
||||
|
||||
* `java -jar target/partitioning-consumer-rabbit-0.0.1-SNAPSHOT.jar --server.port=9007 --spring.cloud.stream.bindings.input.consumer.instanceIndex=2`
|
||||
|
||||
On another terminal start yet another instance of the consumer.
|
||||
|
||||
* `java -jar target/partitioning-consumer-rabbit-0.0.1-SNAPSHOT.jar --server.port=9008 --spring.cloud.stream.bindings.input.consumer.instanceIndex=3`
|
||||
|
||||
* cd ../partitioning-producer
|
||||
|
||||
* `./mvnw clean package -P rabbit-binder`
|
||||
|
||||
* `java -jar target/partitioning-producer-0.0.1-SNAPSHOT.jar --server.port=9010`
|
||||
|
||||
Producer sends messages randomly that has string length of 1, 2, 3, or 4.
|
||||
Watch the consumer console logs and verify that the correct instances are receiving the messages.
|
||||
The first consumer we started should receive messages with a string length of 1 (partition-0), second consumer with `instanceIndex` set to 1 should receive messages with string length of 2 (partittion-1) so on and so forth.
|
||||
|
||||
Once you are done testing, stop all the instances.
|
||||
|
||||
* `docker-compose -f docker-compose-rabbit.yml down`

Spring Cloud Stream Partitioning Sample
|
||||
========================================
|
||||
|
||||
These sample apps demonstrate how partitioning works in Spring Cloud Stream with Apache Kafka.
|
||||
Sample producer and consumer are provided.
|
||||
|
||||
## Quick introduction
|
||||
|
||||
The producer used in the sample produces messages with text that has a length of 1, 2, 3 or 4.
|
||||
There is a configuration in the producer's application.yml file for `partition-key-expression` that uses the length of the payload minus 1 as the partition key expression to use.
|
||||
This value will be used by the binder for selecting the correct partition based on the total number of partitions configured on the destination at the broker.
|
||||
We use 4 partitions for this demo.
|
||||
|
||||
## Running the samples
|
||||
|
||||
The following instructions assume that you are running Kafka as a Docker image.
|
||||
|
||||
* `docker-compose up -d`
|
||||
|
||||
* Ensure that you are in the directory `kafka-partitioning`
|
||||
|
||||
* `./mvnw clean package`
|
||||
|
||||
* `java -jar partitioning-consumer-sample-kafka/target/partitioning-consumer-sample-kafka-0.0.1-SNAPSHOT.jar --server.port=9008`
|
||||
|
||||
On another termimal start another instance of the consumer.
|
||||
|
||||
* `java -jar partitioning-consumer-sample-kafka/target/partitioning-consumer-sample-kafka-0.0.1-SNAPSHOT.jar --server.port=9009`
|
||||
|
||||
On another terminal start the producer.
|
||||
|
||||
* `java -jar partitioning-producer-sample-kafka/target/partitioning-producer-sample-kafka-0.0.1-SNAPSHOT.jar --server.port=9010`
|
||||
|
||||
Producer sends messages randomly that has string length of 1, 2, 3, or 4.
|
||||
Watch the consumer console logs and verify that the correct partitions are receiving the messages.
|
||||
The log message has the payload and partition information in it.
|
||||
|
||||
Once you are done testing, stop all the instances.
|
||||
|
||||
* `docker-compose down`

Spring Cloud Stream Partitioning Sample
|
||||
========================================
|
||||
|
||||
These sample apps demonstrate how partitioning works in Spring Cloud Stream with RabbitMQ.
|
||||
Sample producer and consumer are provided.
|
||||
|
||||
## Quick introduction
|
||||
|
||||
The producer used in the sample produces messages with text that has a length of 1, 2, 3 or 4.
|
||||
There is a configuration in the producer's application.yml file for `partition-key-expression` that uses the length of the payload minus 1 as the partition key expression to use.
|
||||
This value will be used by the binder for selecting the correct partition based on the total number of partitions configured on the destination at the broker.
|
||||
We use 4 partitions for this demo.
|
||||
|
||||
## Running the samples
|
||||
|
||||
The following instructions assume that you are running Rabbit as a Docker image.
|
||||
|
||||
* `docker-compose up -d`
|
||||
|
||||
* Ensure that you are in the directory `rabbit-partitioning`
|
||||
|
||||
* `./mvnw clean package`
|
||||
|
||||
Rabbit partitioning demo is slightly different from Kafka.
|
||||
We need to spin up 4 consumers for each of the four partitions.
|
||||
|
||||
* `java -jar partitioning-consumer-sample-rabbit/target/partitioning-consumer-sample-rabbit-0.0.1-SNAPSHOT.jar --server.port=9005`
|
||||
|
||||
On another terminal start another instance of the consumer.
|
||||
|
||||
* `java -jar partitioning-consumer-sample-rabbit/target/partitioning-consumer-sample-rabbit-0.0.1-SNAPSHOT.jar --server.port=9006 --spring.cloud.stream.bindings.listen-in-0.consumer.instanceIndex=1`
|
||||
|
||||
On another terminal start another instance of the consumer.
|
||||
|
||||
* `java -jar partitioning-consumer-sample-rabbit/target/partitioning-consumer-sample-rabbit-0.0.1-SNAPSHOT.jar --server.port=9007 --spring.cloud.stream.bindings.listen-in-0.consumer.instanceIndex=2`
|
||||
|
||||
On another terminal start yet another instance of the consumer.
|
||||
|
||||
* `java -jar partitioning-consumer-sample-rabbit/target/partitioning-consumer-sample-rabbit-0.0.1-SNAPSHOT.jar --server.port=9008 --spring.cloud.stream.bindings.listen-in-0.consumer.instanceIndex=3`
|
||||
|
||||
On another terminal start the producer.
|
||||
|
||||
* `java -jar partitioning-producer-sample-rabbit/target/partitioning-producer-sample-rabbit-0.0.1-SNAPSHOT.jar --server.port=9010`
|
||||
|
||||
Producer sends messages randomly that has string length of 1, 2, 3, or 4.
|
||||
Watch the consumer console logs and verify that the correct instances are receiving the messages.
|
||||
The first consumer we started should receive messages with a string length of 1 (partition-0), second consumer with `instanceIndex` set to 1 should receive messages with string length of 2 (partition-1) so on and so forth.
|
||||
|
||||
Once you are done testing, stop all the instances.
|
||||
|
||||
* `docker-compose down`
