Basics

What is a datacenter? What tasks do we have there?

  • Easy to scale or adopt to new requirements.
  • Handling peak performance is easier.
  • Less infrastructure bulls**t because the interaction with the hardware layer is minimized.

Why AWS is good, when to use?

  • Wouldn’t put bank application on it (for a good reason).

https://www.elastic.co/guide/en/elasticsearch/reference/5.2/query-cache.html

CreateIndexRequestBuilder cirb = new CreateIndexRequestBuilder(esTransportClient.admin().indices()).setIndex(index);
ImmutableSettings.Builder indexSettings = ImmutableSettings.settingsBuilder();
indexSettings.put("analysis.analyzer.default.type", "cjk");
cirb.setSettings(indexSettings);
