7.00pm - Talk - "Real-time full-text search for streaming data with Luwak, Kafka and Samza" by Alan Woodward
Traditionally, search works like this: you have a large corpus of documents, and users write ad-hoc queries to find documents within that corpus. Documents may change from time to time, but on the whole, the corpus is fairly stable.
However, with fast-changing data, it can be useful to turn this model on its head, and search over a stream of documents as they appear. For example, companies may want to detect whenever they are mentioned in a feed of news articles, or a Twitter user may want to see a continuous stream of tweets for a particular hashtag.
In this talk, we describe open source tools that enable search on streams: Luwak is a Lucene-based library for running many thousands of queries over a single document, with optimizations that make this process efficient. Samza is a stream processing framework based on Kafka, allowing real-time computations to be distributed across a cluster of machines. We show how Luwak and Samza can be combined into an efficient and scalable streaming search engine.
Alan Woodward is a director of Flax, the Cambridge-based open source search specialists, and a committer to the Apache Lucene/Solr project. Alan is the author of Luwak, Flax's scalable stored search library used by companies such as Bloomberg and Infomedia A/S in their large-scale media monitoring systems. Alan has also recently built log analytics systems using Logstash, Apache Kafka and Elasticsearch.
