Java client for Dynomite

Dyno

Dyno encapsulates features necessary to scale a client application utilizing Dynomite.

See the blog post for introductory info.

See the wiki for documentation and examples.

Dyno Client Features

• Connection pooling of persistent connections - this helps reduce connection churn on the Dynomite server with client connection reuse.
• Topology aware load balancing (Token Aware) for avoiding any intermediate hops to a Dynomite coordinator node that is not the owner of the specified data.
• Application specific local rack affinity based request routing to Dynomite nodes.
• Application resilience by intelligently failing over to remote racks when local Dynomite rack nodes fail.
• Application resilience against network glitches by constantly monitoring connection health and recycling unhealthy connections.
• Capability of surgically routing traffic away from any nodes that need to be taken offline for maintenance.
• Flexible retry policies such as exponential backoff etc
• Insight into connection pool metrics
• Highly configurable and pluggable connection pool components for implementing your advanced features.

Build

Dyno comes with a Gradle wrapper.

git clone https://github.com/Netflix/dyno.git
