“Data stream” is a word that can be used in multiple ways. A stream can refer to data in motion or data at rest.  When a stream is data in motion, an endpoint is receiving new pieces of data on a continual basis. Each new data point is sent over the wire and captured by the other end. Another way a stream can be represented is as a sequence of events that have been written to a storage medium. This is a stream at rest. Pravega is a system for storing large streams of data. Pravega can be used as an alternative to systems like Apache Kafka or Apache Pulsar. Flavio Junqueira is an engineer at Dell EMC who works on Pravega. He joins the show to talk about the history of stream processing and his work on Pravega.

Pravega: Storage for Streams with Flavio Junqueira

Apache ZooKeeper enables highly reliable distributed coordination.  Flavio Junqueira is a committer and PMC of Apache ZooKeeper, and former VP of ZooKeeper. Questions include:  Why is master election so important in Hadoop? How does a new user begin working with ZooKeeper? How do nodes “watch” each other? Should ZooKeeper be used as a message queue or notification system? What is ZooKeeper’s place in a data center made increasingly complicated by tools like Mesos and Docker? How will the interactions between managed Big Data companies change in the future? Why wasn’t a company built around ZooKeeper? What is the future of the data center?  Links:  ZooKeeper: Distributed Process Coordination by Flavio Junqueira and Ben Reed Apache ZooKeeper home page Keep moving forward: Liveness in distributed systems by Flavio Junqueira Libsei: scalable error isolation for distributed systems Apache Kafka with Flavio on SE Radio   The post Apache ZooKeeper with Flavio Junqueira appeared first on Software Engineering Daily.
