It's time for the second Elastic meetup at "The Cube Athens" on June 4th 2018!

We are happy to host two speakers:

• Errikos Koen, engineer at E-Travel S.A., presenting: "From Splunk to the Elastic Stack: The Good, the Bad and the Ugly",

Abstract:
An insight look of E-Travel S.A's (pamediakopes.gr etc) journey migrating from Splunk to the Elastic stack

• Philipp Krenn, Developer Advocate at Elastic, presenting "Make Your Data FABulous",
  Abstract:

The CAP theorem is widely known for distributed systems, but it's not the only tradeoff you should be aware of. For datastores there is also the FAB theory and just like with the CAP theorem you can only pick two:

• Fast: Results are real-time or near real-time instead of batch oriented.
• Accurate: Answers are exact and don't have a margin of error.
• Big: You require horizontal scaling and need to distribute your data.

While Fast and Big are relatively easy to understand, Accurate is a bit harder to picture. This talk shows some concrete examples of accuracy tradeoffs Elasticsearch can take for terms aggregations, cardinality aggregations with HyperLogLog++, and the IDF part of full-text search. Or how to trade some speed or the distribution for more accuracy.

So, what is the Elastic Stack?

The Elastic Stack is the next evolution of ELK, where "ELK" is the acronym for three open source projects: Elasticsearch, Logstash, and Kibana. Elasticsearch is a search and analytics engine. Logstash is a server‑side data processing pipeline that ingests data from multiple sources simultaneously, transforms it, and then sends it to a "stash" like Elasticsearch. Kibana lets users visualize data with charts and graphs in Elasticsearch.
