An Advanced HTTP Reverse Proxy with Dynamic Sharding Strategies

Weaver

Weaver is a Layer-7 Load Balancer with Dynamic Sharding Strategies. It is a modern HTTP reverse proxy with advanced features.

Features:

  • Sharding request based on headers/path/body fields
  • Emits Metrics on requests per route per backend
  • Dynamic configuring of different routes (No restarts!)
  • Is Fast
  • Supports multiple algorithms for sharding requests (consistent hashing, modulo, s2 etc)
  • Packaged as a single self contained binary
  • Logs on failures (Observability)

Installation

Build from source

  • Clone the repo:
git clone [email protected]:gojektech/weaver.git
  • Build to create weaver binary
make build

Architecture

weaver_architecture

Weaver uses etcd as a control plane to match the incoming requests against a particular route config and shard the traffic to different backends based on some sharding strategy.

Weaver can be configured for different routes matching different paths with various sharding strategies through a simple route config named ACL.

The various sharding strategies supported by weaver are:

  • Consistent hashing (hashring)
  • Simple lookup based
  • Modulo
  • Prefix lookup
  • S2 based

Examples

We have examples defined to deploy it to kubernetes and using acls.

Configuration

Please note

As the famous saying goes, All Load balancers are proxies, but not every proxy is a load balancer, weaver currently does not support load balancing.
