What is RethinkDB?

Open-source database for building realtime web applications
NoSQL database that stores schemaless JSON documents
Distributed database that is easy to scale
High availability database with automatic failover and robust fault tolerance

RethinkDB is the first open-source scalable database built for
realtime applications. It exposes a new database access model, in
which the developer can tell the database to continuously push updated
query results to applications without polling for changes. RethinkDB
allows developers to build scalable realtime apps in a fraction of the
time with less effort.

First install some dependencies. For example, on Ubuntu or Debian:

Generally, you will need

GCC or Clang
Protocol Buffers
jemalloc
Ncurses
Python 2 or Python 3
libcurl
libcrypto (OpenSSL)
libssl-dev

Then, to build:

See WINDOWS.md and mk/README.md for build instructions for Windows and
FreeBSD.
