Meet Apache Samza – LinkedIn’s Stream Processing Framework

Meet Apache Samza - LinkedIn’s Stream Processing FrameworkWith the advent of Big Data and the rapidly growing scale of web-applications, monolithic relational databases were replaced by scalable, partitioned, NoSQL databases and HDFS; individual queries to relational databases were replaced by the likes of Hive and Pig.

That’s when LinkedIn came up with Samza. Apache Software Foundation’s incubation project since September 2013, Apache Samza is the distributed stream processing framework that incorporates Apache Kafka for messaging, and Apache Hadoop YARN to provide fault tolerance, processor isolation, security, and resource management.

How to Interview a Data ScientistYou know the feeling. You’re sat across the table from an interviewee and the conversation starts to run away from you. Your eyes start scanning the room as they’re reeling off another jargon-crammed answer. You notice the chip in the Channing Tatum mug you received from the office Secret Santa last Christmas. You then notice the scratch on your hand that your 4 year old gave you, in exchange for closing the laptop during that far too familiar One Direction song. The only thing you’re not noticing are the answers the other person in the room has been reeling off at you. If this typically happens to you most when you’re conducting technical interviews, it could be either that the person your interviewing is talking in a language not known...
