Back with Big Data Streams

I am slowly getting back to thinking about streams. In the past few years, new systems seem to have emerged that process streams.

• See the upcoming meeting in NY on Twitter's Cassandra and open source platform Storm (for continuous queries, distributed query processing, fault tolerance)
• Yahoo's S4 distributed stream platform which is a "general-purpose, distributed, scalable, partially fault-tolerant, pluggable platform that allows programmers to easily develop applications for processing continuous unbounded streams of data."
