Heya all!

As we kick into fall, we are super excited to announce our next Meetup at Stack Overflow. We welcome Andrew Montaleni, co-founder & CTO of Parse.ly, as our guest speaker. Andrew will be giving a talk titled: Improving High-Cardinality Analytics with Index-Stored HyperLogLogs

From the Elastic side, Peter Soderberg, Elastic Solutions Architect, will be speaking about the first open source APM: Elastic APM.

NB: Stack Overflow is located on the 28th floor.

**BONUS: We will be giving away a free ticket to the Elastic{ON} Tour - NY at this event.** (https://www.elastic.co/elasticon/tour/new-york)

Talk 1: Improving High-Cardinality Analytics with Index-Stored HyperLogLogs

Abstract:
One of Elasticsearch's most powerful analytics features is the "cardinality" aggregation, which can do blazing-fast distinct counts across millions of high-cardinality document values by leveraging the probabilistic data structure, HyperLogLog++ (aka HLL). In this presentation, Andrew Montalenti, the co-founder & CTO of Parse.ly, will discuss the open source work his team has done to bring "index-stored HLLs" to Elasticsearch. We'll begin with a discussion of what HLL is & how it works -- in other words, how cardinality aggregations work, under-the-hood. Then we'll discuss why massive cost & performance savings (on the order of 10x) can come from index-storage of serialized HLLs, with the key trade-off being individual value searchability. Finally, we'll showcase how a small team of (primarily Python) programmers managed to get its head around Elasticsearch's Java codebase in order to build a new custom aggregation & a new index type to support this use case, & why we're releasing this functionality as open source. We'll close with a discussion of the broader effort for index-stored data sketches in ES, which, in the future, might include the percentiles aggregation & its TDigest data structure.

Talk 2: Elastic APM

Abstract:
Over the last few years, Elastic has focused on optimizing the Elastic Stack for the use cases adopted by our community. This talk will focus on Elastic APM - the first open source APM solution. We'll explore instrumenting an application, the data model for metrics & logs, distributed tracing, & real user monitoring--the tools that enable realtime monitoring & intuitive troubleshooting.
