This document provides an overview and agenda for a CouchDB relaxation session at OSC 2009 Tokyo/Fall. It introduces the speakers and topics, which include basic relaxation, social relaxation, and CMS relaxation. Details are then provided on CouchDB versions, Windows installers, related projects, and the CouchDB JP community group. The bulk of the document consists of slides from a presentation on basic CouchDB concepts, including accessing documents via HTTP, storing data as JSON, using design documents to customize views and formatting, and replication between CouchDB servers. Examples of suitable data types for CouchDB are given as documents, cards, books, source code, and configuration files. Setting up and using CouchDB is encouraged to relax with one's data

The SlideShare 101 is a quick start guide if you want to walk through the main features that the platform offers. This will keep getting updated as new features are launched.
The SlideShare 101 replaces the earlier "SlideShare Quick Tour".
Two years ago, Spotify introduced Scio, an open-source Scala framework to develop data pipelines and deploy them on Google Dataflow. In this talk, we will discuss the evolution of Scio, and share the highlights of running Scio in production for two years. We will showcase several interesting data processing workflows ran at Spotify, what we learned from running them in production, and how we leveraged that knowledge to make Scio faster, and safer and easier to use.
I'm learning elasticsearch now.

6. Document-Oriented Database
For example here's a document:
FirstName="Bob", Address="5 Oak St.", Hobby="sailing".
Another document could be:
FirstName="Jonathan", Address="15 Wanamassa Point Road", Children=("Michael,
10", "Jennifer,8", "Samantha,5", "Elena,2").
Notice that both documents have some similar information and some different - but
unlike a relational database where each record would have the same set of fields and
unused fields might be kept empty, there are no empty 'fields' in either document
(record) in this case. This system allows information to be added any time without
wasting storage space for "empty fields" as in relational databases.
