What does it even mean to query streaming data, and how does this compare to a SQL database? Well, it’s actually quite different to a SQL database. Most databases are used for doing on-demand lookups and modifications to stored data. KSQL doesn’t do lookups (yet), what it does do is continuous transformations— that is, stream processing. For example, imagine that I have a stream of clicks from use
May 24, 2016 - The capabilities of open source systems for distributed stream processing have evolved significantly over the last years. Initially, the first systems in the field (notably Apache Storm) provided low latency processing, but were limited to at-least-once guarantees, processing-time semantics, and rather low-level APIs. Since then, several new systems emerged and pushed the state of t
Streaming is necessary to handle IoT data rates and latency but SQL is unquestionably the lingua franca of data. Apache Samza and Apache Storm have new high-level query interfaces based on standard SQL with streaming extensions, both powered by Apache Calcite. Calcite's relational algebra allows query optimization and federation with data-at-rest in databases, memory, or HDFS. A talk given by Juli
With the rise of the Internet of Things (IoT) and low-latency analytics, streaming data becomes ever more important. Surprisingly, one of the most promising approaches for processing streaming data is SQL. In this presentation, Julian Hyde shows how to build streaming SQL analytics that deliver results with low latency, adapt to network changes, and play nicely with BI tools and stored data. He al
Now, next, and beyond: Tracking need-to-know trends at the intersection of business and technology AI/ML Few technologies have the potential to change the nature of work and how we live as artificial intelligence (AI) and machine learning (ML).
