The database for the realtime web
Jorge Silva @thejsj Developer Evangelist @ RethinkDB
Preface Why is realtime important?
Realtime apps
Realtime apps
Realtime apps • More and more apps are built to
be realtime • Users have come to want and expect this behavior in their apps
Building realtime apps is hard • You can keep everything
in a single server • You can poll the database to keep track of updates • You can publish updates through a message broker
Building realtime apps is hard • All solutions present a
tradeoff between scalability and complexity • It’s hard to keep track of state in realtime architectures.
Introduction What is RethinkDB?
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
Built for Realtime Apps • Subscribe to change notifications from
database queries • No more polling — the database pushes changes to your app • Reduce the amount of plumbing needed to stream live updates
Built for Realtime Apps RethinkDB is an excellent database for:
• Collaborative web and mobile apps • Multiplayer games • Streaming analytics apps • Realtime marketplaces • Connected devices
Introduction to ReQL RethinkDB Query Language
Introduction to ReQL • ReQL embeds natively into your programming
language • Compose ReQL queries by chaining commands
Anatomy of a ReQL Query r.table("players") .orderBy({ index: r.desc("score") })
.limit(3) Top three players by score
Anatomy of a ReQL Query r.table("players") .orderBy({ index: r.desc("score") })
.limit(3) Access a database table
Anatomy of a ReQL Query r.table("players") .orderBy({ index: r.desc("score") })
.limit(3) Order results
Anatomy of a ReQL Query r.table("players") .orderBy({ index: r.desc("score") })
.limit(3) Use index as pre-processed lookup
Anatomy of a ReQL Query r.table("players") .orderBy({ index: r.desc("score") })
.limit(3) Order results in descending order
Anatomy of a ReQL Query r.table("players") .orderBy({ index: r.desc("score") })
.limit(3) Only get the first three results
Subscribe to change notifications on database queries Changefeeds
r.table("users").changes() Track changes on the users table Changefeeds
Changefeeds r.table("players") .orderBy({ index: r.desc("score") }) .limit(3) .changes() Get updates
on top three players
