The past years I have been working with search solutions, mostly elasticsearch. During this time a bought myself a raspberry pi and installed java and elasticsearch on it. Then I put it in the closet and it did not come out anymore. Than a few weeks a go the guys from elasticsearch released marvel. Marvel is a monitoring tool for your elasticsearch cluster. Suddenly I realized what the problem with the raspberry pi is. It is not fun to have just one. Therefore I decided to buy two more and create an elasticsearch cluster. With this cluster I can do experiments. The first experiment is evaluating marvel.

In this blog post I will show some of the concepts of marvel. To make this possible I will also explain the steps I had to take to install elasticsearch on my raspberry pi cluster.

elasticsearch – how many shards?

We’ve all been there – you’re provisioning for an elasticsearch index and one of the first questions that comes to mind is “how many shards should I create my index with?”. In my previous posts on the subject, I wrote about how to find the maximum shard size for elasticsearch. Although informative, the results of the tests also raised a new question: would more shards on a single elasticsearch node increase performance? In this blog post I’m going to try to show the performance consequences of different choices for the number of shards.

Last Friday I was with Elissa, Boaz and Shay from Elasticsearch and with Henk and Thomas from TriforkĀ at the Open Source conference where Trifork had a joint stand together with Elasticsearch. The Open Source conference is an annual event in the Benelux gathering industry leaders and speakers on the topics big data, cloud, mobile and social strategies. This year the event took place at Beurs Van Berlage in Amsterdam.

How to avoid the split-brain problem in elasticsearch

Elasticsearch LogoWe’ve all been there – we started to plan for an elasticsearch cluster and one of the first questions that comes up is “How many nodes should the cluster have?”. As I’m sure you already know, the answer to that question depends on a lot of factors, like expected load, data size, hardware etc. In this blog post I’m not going to go into the detail of how to size your cluster, but instead will talk about something equally important – how to avoid the split-brain problem.
