Join us on Tuesday, August 23 for our upcoming meetup in Mountain View. Doors open at 6pm and talks start at 6:30pm. 

• VoiceBase's John Bocharov on "Using Elastic to power voice search and analytics at VoiceBase" 

• SignalFx's Mahdi Ben Hamida on "Zero-Downtime Re-Indexing of Elasticsearch at SignalFx" 

Great conversation, food, and beverages will be provided!

Zero-Downtime Re-Indexing of Elasticsearch at SignalFx.

Certain changes in Elasticsearch, such as number of primary shards and mapping changes, require re-indexing. This can be challenging to do depending upon your data flows and uptime requirements. At SignalFx, we have designed our indexing pipeline to allow for a full re-indexing without impacting our service or its users. In this talk, Mahdi will present SignalFx's polyglot metadata search infrastructure and go through the zero-downtime re-indexing process. He will also talk about the lessons learned running this in production as well as how we plan to use this to do a zero-downtime upgrade from Elasticsearch 1.7 to 2.0.

Mahdi is a software engineer with a decade of experience writing software. Previously, he spent 7 years at VMware building key components of its cloud management stack. At SignalFx, Mahdi enjoys the challenges of concurrency and distributed systems while working on the search and metadata persistence layers. 

Using Elastic to power voice search and analytics at VoiceBase

At VoiceBase, we use Elastic to power search and analytics based on recorded speech, driven by our speech-to-text, semantic indexing, and predictive technologies. In addition, Elastic is helping our customers solve key problems of multi-tenancy, rich metadata integration, and interactive phrase ("keyword") spotting. In this talk, we will share how we integrate Elastic into our offering, and practical lessons learned along the way.

John Bocharov (Director of Engineering @ VoiceBase) manages a team of high-caliber engineers responsible for orchestrating speech analytics, over thousands of compute cores. Previously, he and his teams built a recommendation engine with Lambda architecture (before it was cool) and products for adaptive bit rate streaming over HTTP (way before it was cool). John is passionate about data products, fútbol, and toe socks. In fact, he is probably wearing a pair right now.
