July meetup: Scala, Spark, Docker, Elasticsearch

Hello everybody,

hoping that not that many of you will be in holiday on July 20, we decided to have a meetup in July. See below the presentations & presenters (thank you Adrian Tanase and Radu Gheorghe for bringing up really interesting subjects), we're gonna discuss Scala and Spark, Docker and Elasticsearch.

19:00 - 19:30 gathering and socialization

19:30 - 20:10 Scala and building Spark applications, Adrian Tanase (https://www.linkedin.com/in/adrian-tanase-b7b10aa/) @ Adobe Romania

20:10 - 20:40 Using Docker with Elasticsearch (or other Big Data storage backends): Benefits and Challenges, Radu Gheorghe (https://www.linkedin.com/in/ragheorghe/) @ Sematext

Let's discuss about both high-level and low-level Dockerstuff. We know (do we?) that Docker works well for microservices and for development, but what about storage engines running in production,which typically need medium/big boxes already? Taking Elasticsearch as a case study - which is easily translatable to other big data tools, especially if they're Java-based - we'll have a look at advantages and disadvantages of containerizing. Then, we'll have a closer look under the hood, at things that we tend to bump into: things like OS caches, OOM killer, garbage collection options, JVM bugs - you know, the interesting stuff :) Please bring your own facts and opinions!

20:40 - 21:30 socialization & pizza sponsored by Netopia (http://wp.netopia.ro/).

See you all there,

Valentina
