1. 1 Tips & Tricks about Apache Kafka in the Cloud for Java Developers Ricardo Ferreira, Developer Advocate @riferrei
3. 3 About Us: • Ricardo Ferreira ◦ Developer Advocate @ Confluent ◦ Ex-Oracle, Red Hat, IONA Tech ◦ Currently ~10% Smart, ~90 Dumb ◦ https://riferrei.net • Echo Dot (Alexa) ◦ The voice behind Amazon ◦ Ex-Raspberry Pi, Arduino, T3? ◦ Currently ~90% Smart, ~10 Dumb @riferrei @alexa99
4. 4 #1 Managed Kafka Services • Kafka is a fine proven technology • People don’t know/care internals • Human labor is often too costly • Install-patch-monitor-scale repeat • Build applications, not clusters! https://www.confluent.io/confluent-cloud @riferrei @jeeconf
5. 5 Let's Create a Cluster 1. Log in to the Confluent Cloud. 2. Create a new cluster on-the-fly. 3. Connect your Java applications. https://confluent.cloud @riferrei @jeeconf
6. 6 http://kafka.apache.org/documentation.ht ml#connect https://docs.confluent.io/current/connect /quickstart.html https://debezium.io #2 Apache Kafka Connect • Moving data in-and-out is hard • +75 connectors available now • Integrated with Schema Registry • CDC via Red Hat's Debezium • Connectivity code is you, let the Serialization, Partitioning, Fault- Tolerance, Schema Mgmt on us. @riferrei @jeeconf
7. 7 Pushing Data to Redis Cache using Apache Kafka Connect @riferrei @jeeconf
8. 8 Connecting the Layers 1. Please scan the barcode below. 2. Listen the song and try to guess. 3. Enter with your name and send. @riferrei @jeeconf
9. 9 #3 Kafka Streams and KSQL • Create stream processing apps • Data computation outside Kafka • Same partitioning/scaling model • Complex pipelines using filters, aggregations, windows & more. • Flavors: Java, Scala and KSQL https://kafka.apache.org/documentation/ streams https://www.confluent.io/product/ksql @riferrei @jeeconf
10. 10 @riferrei @jeeconf Processing the Data In-Motion and Creating a New Data Set
11. 11 #4 Distributed Tracing • Monitor distributed transactions • Glue your Java code with Kafka • Trace producers and consumers • Decorators and Interceptors API • Trace Kafka services such as REST Proxy, Connect and KSQL https://github.com/opentracing-contrib/java-kafka- client https://github.com/riferrei/jaeger-tracing-support @riferrei @jeeconf
12. 12 https://github.com/opentracing-contrib/java-kafka- client https://github.com/riferrei/jaeger-tracing-support @riferrei @jeeconf Tomorrow: 11:05 – 11:50 Implementing Distributed Tracing 'Like a Boss' in your Apache Kafka Deployments
13. 13 #5 Infrastructure-as-Code • Create immutable infrastructure • Handle dependencies of the code • Build your Java code on-the-fly • Connect with Cloud automatically • Blend Kafka services with infra https://github.com/confluentinc/cp-docker-images https://github.com/confluentinc/cp-helm-charts https://github.com/confluentinc/ccloud-tools https://github.com/confluentinc/cp-ansible @riferrei @jeeconf
