# rholder/guava-retrying

This is a small extension to Google's Guava library to allow for the creation of configurable retrying strategies for an arbitrary function call, such as something that talks to a remote service with flaky uptime.

## What it is
A small Java library extending Google Guava that provides configurable retrying strategies for arbitrary function calls via a RetryerBuilder DSL. It supports retry conditions based on results or exceptions, stop strategies, and exponential or Fibonacci backoff wait strategies.

## Use cases
- retry flaky remote service calls in Java
- add exponential backoff to API requests
- retry a callable until it succeeds or attempts run out
- retry only on specific exception types
- implement well-behaved service polling with backoff
- wrap unreliable network operations with configurable retries

## When to choose
- you're on the JVM and already use Guava
- you need fine-grained control over retry conditions, stop rules, and wait strategies
- you want a lightweight, focused retry library without pulling in a full resilience framework

## When to avoid
- you need circuit breaking, rate limiting, or bulkheading alongside retries (consider Resilience4j)
- you're not using Java/JVM languages
- you need a library under active development with frequent updates

## Facets
- artifact type: library
- maturity: maintenance
- function: error-handling, concurrency, developer-tools
- domain: developer-tools, backend, microservices
- platform: jvm
- tags: retry, retryer, guava, backoff, resilience, java-library
