Swage

Swage is a collection of libraries useful for developing and running services.

Currently it consists of the following Java libraries:

  • Metrics
  • Type Safe
  • Thread Context
  • Disseminating Executors

Metrics

The Swage Metrics library provides a clean, robust API for recording metric events in a Java application, as well as a core implementation for sending the instrumented metric data to AWS CloudWatch.

It consists of the following modules:

  • metrics-core
  • metrics-api

Type Safe

Swage Type Safe is a small library that provides type-safe solutions that are not part of the Java standard libraries. At the moment it consists soley of the TypedMap, a class for storing heterogenous key/value pairs in a a type safe way.

It lives in the type-safe module.

Thread Context

Swage Thread Context is a library to help manage and propagate task context in an application across threads. Where a ThreadLocal can help manage context within one thread, this library provides a way to manage context where a task may span many threads.

It lives in the thread-context module.

Disseminating Executors

The Disseminating Executors library solves the same basic problem as the Thread Context library, but with a different approach. Ths library is intended to allow targetd state to cross thread boundaries without invasive changes at every execution point. It uses custom task executors to capture and propagate state.

It lives in the disseminating-executors module.
