http://traffic.libsyn.com/sedaily/mesos-and-kubernetes_edited_1.mp3Podcast: Play in new window | Download Mesos and Kubernetes are tools for distributed systems management. Kubernetes is built with an emphasis on running services, whereas Mesos is commonly used for a wider variety of workloads, including data infrastructure like Spark and Kafka. Mesos can also be used as a platform to provide resource management for Kubernetes. Dharmesh Kakadia is the author of Apache Mesos Essentials, and has spent time
http://traffic.libsyn.com/sedaily/event_sourcing_edited.mp3Podcast: Play in new window | Download When a user of a social network updates her profile, that profile update needs to propagate to several databases that want to know about such an update–search indexes, user databases, caches, and other services. When Neha Narkhede was at LinkedIn, she helped develop Kafka, which was deployed at LinkedIn to help solve this very problem. Using Kafka as an event queue, LinkedIn adopted
http://traffic.libsyn.com/sedaily/scaling_emails_Edited.mp3Podcast: Play in new window | Download “As the scale continues to increase, certain effects of architecture become less and less efficient.” When you spend money online, you expect a receipt to come in your email. When you register for a new web site, you need to verify your sign up in your email. These types of emails are called “transactional email” and sending these types of email at scale
From Nicolae Marasoiu’s answer via Quora: Kafka is a high performance messaging system which provides an immutable, linearizable, sharded log of messages. Throughput and storage capacity scale linearly with nodes. Kafka can push astonishingly high volume through each node; often saturating disk, network, or both, while keeping a low cpu utilization. You would use Kafka in scenarios of asynchronous communication and processing pipelines, predominantly in distributed systems, cloud & big data,
“Systems are giving up correctness for latency, and I’m arguing that stream processing systems have to be designed to allow the user to pick the tradeoffs that the application needs.”
“My bet is that there is going to be a big shift towards streaming technologies in the future.”
Apache Flink is an open-source framework for distributed stream and batch data processing.
Databases Week began with a set of fundamental questions. What is a database? Every interviewee during Database Week has given a different answer to the question of "What is a database?" — SE Daily (@software_daily) August 21, 2015 One definition: “an application component for storing and retrieving data”. All of the different databases companies have this functionality. But similarities end there. RethinkDB pushes data to the application MemSQL is a faster, proprietary version

VoltDB provides streaming analytics with transactions. Questions How does VoltDB exemplify Michael Stonebraker’s thesis that one size does not fit all? What is the difference between OLTP and Streaming? How does VoltDB serve the common Zookeeper-Kafka-Storm-Cassandra stack? What trends and requirements among OLTP and OLAP systems are changing most

Questions What are continuous views? Why is PipelineDB a good fit for the Kafka+Storm+HBase-type architecture? How does PipelineDB affect the application tier or the browser tier? What are the latency guarantees for how long it takes raw data streams to be converted into the refined queries provided by a continuous view?
Fundamental questions as big as data itself loomed at the beginning of Big Data Week. Some answers: How do customers of multiple managed big data companies deal with the heterogeneity? Confluent provides Kafka, Rocana provides ops, Databricks gives you data science, Cloudera and Hortonworks give you everything else. Each company has a proprietary layer meshed with open-source software. Generally, the more proprietary software you are running, the more you will need
