Apache Kafka Meetup @ Zalando

Welcome to the next Helsinki Apache Kafka Meetup hosted by Zalando.

Doors open at 17:30, first talk starts at 18:00. Welcome!

Agenda:

• Nakadi Event Broker - Dmitriy Sorokin, Zalando

Nakadi is an event broker, built on top of Kafka-like queues, that provides a REST API for easy integration with microservices. In this talk, we will briefly introduce Nakadi, and then focus on one of its most interesting features, Timelines.

Timelines allow administrators to transparently move topics between different clusters, without interrupting producers or consumers. This is useful to move between clusters, possibly using different technologies, but also as a fail-over for publishers in case of downtime on a cluster. Timelines can also be used to move event types between brokers on the same cluster, which is an alternative to rebalance operations. Contrary to rebalance operations, using timelines does not require additional data copy between brokers, which can slow them down. We also have plans to use timelines for re-partitioning, i.e. changing the number of partitions in an event type.

• Debezium & Change Data Capture from PostgresQL to Kafka, Hannu Valtonen, Aiven
