This talk was given during Lucene Revolution 2017 and has two goals: first, to discuss the tradeoffs for running Solr on Docker. For example, you get dynamic allocation of operating system caches, but you also get some CPU overhead. We'll keep in mind that Solr nodes tend to be different than your average container: Solr is usually long running, takes quite some RSS and a lot of virtual memory. This will imply, for example, that it makes more sense to use Docker on big physical boxes than on configurable-size VMs (like Amazon EC2).

They say optimize is bad for you, they say you shouldn't do it, they say it will invalidate operating system caches and make your system suffer. This is all true, but is it true in all cases? In this presentation we will look closer on what optimize or better called force merge does to your Solr search engine. You will learn what segments are, how they are built and how they are used by Lucene and Solr for searching.

Lennart Koopmann and Taylor Rhoades talk about the new features in Graylog v2.3.0. In this release, we introduced lookup tables and support for Elasticsearch 5 which includes the AWS Elasticsearch service.

Here's a quick, in-depth LogDNA tutorial. Learn how the blazing fast, simple log management tool works for easy logging analytics. Centralize logs from all servers, apps, and systems. Search, monitor, analyze, and manage views/alerts with ease.

In this webinar, Michael DeSa will define what time series data is (and isn't), how the problem domain time series differs from more traditional data workloads like full-text search, and examine how InfluxData is differentiated from other proposed solutions.

One of the Sematext differentiators is that it’s not just a monitoring solution or just log management solution. It’s monitoring AND log management in a single solution. This single pane of proverbial glass makes DevOps lives simpler.

Lennart Koopmann and Taylor Rhoades talk about the new features in Graylog v2.2.

We are known worldwide for our Elasticsearch, ELK stack and Solr consulting services, and we are always happy to help others improve their skills in these technologies, not only through Solr & Elastic Stack trainings, but also by sharing our knowledge in meetups and conferences. On 7-9 November 2016, we joined O’REILLY Velocity 2016 conference, discussing the latest tech in Elasticsearch.
