Package com.netflix.hystrix

Core functionality of Hystrix including the HystrixCommand and HystrixCollapser to be extended from.

Description

Interface Summary

HystrixCircuitBreaker	Circuit-breaker logic that is hooked into HystrixCommand execution and will stop allowing executions if failures have gone past the defined threshold.
HystrixCollapser.CollapsedRequest<ResponseType,RequestArgumentType>	A request argument RequestArgumentType that was collapsed for batch processing and needs a response ResponseType set on it by the executeBatch implementation.
HystrixCollapserKey	A key to represent a HystrixCollapser for monitoring, circuit-breakers, metrics publishing, caching and other such uses.
HystrixCommandGroupKey	A group name for a HystrixCommand.
HystrixCommandKey	A key to represent a HystrixCommand for monitoring, circuit-breakers, metrics publishing, caching and other such uses.
HystrixExecutable<R>	Common interface for executables (HystrixCommand and HystrixCollapser) so client code can treat them the same and combine in typed collections if desired.
HystrixThreadPool	ThreadPool used to executed HystrixCommand.run() on separate threads when configured to do so with HystrixCommandProperties.executionIsolationStrategy().
HystrixThreadPoolKey	A key to represent a HystrixThreadPool for monitoring, metrics publishing, caching and other such uses.

Class Summary

Hystrix	Lifecycle management of Hystrix.
HystrixCollapser<BatchReturnType,ResponseType,RequestArgumentType>	Collapse multiple requests into a single HystrixCommand execution based on a time window and optionally a max batch size.
HystrixCollapser.Setter	Fluent interface for arguments to the HystrixCollapser constructor.
HystrixCollapserKey.Factory
HystrixCollapserProperties	Properties for instances of HystrixCollapser.
HystrixCollapserProperties.Setter	Fluent interface that allows chained setting of properties that can be passed into a HystrixCollapser constructor to inject instance specific property overrides.
HystrixCommand<R>	Used to wrap code that will execute potentially risky functionality (typically meaning a service call over the network) with fault and latency tolerance, statistics and performance metrics capture, circuit breaker and bulkhead functionality.
HystrixCommand.Setter	Fluent interface for arguments to the HystrixCommand constructor.
HystrixCommandGroupKey.Factory
HystrixCommandKey.Factory
HystrixCommandMetrics	Used by HystrixCommand to record metrics.
HystrixCommandMetrics.HealthCounts	Number of requests during rolling window.
HystrixCommandProperties	Properties for instances of HystrixCommand.
HystrixCommandProperties.Setter	Fluent interface that allows chained setting of properties that can be passed into a HystrixCommand constructor to inject instance specific property overrides.
HystrixRequestCache	Cache that is scoped to the current request as managed by HystrixRequestVariableDefault.
HystrixRequestLog	Log of HystrixCommand executions and events during the current request.
HystrixThreadPoolKey.Factory
HystrixThreadPoolMetrics	Used by HystrixThreadPool to record metrics.
HystrixThreadPoolProperties	Properties for instances of HystrixThreadPool.
HystrixThreadPoolProperties.Setter	Fluent interface that allows chained setting of properties that can be passed into a HystrixThreadPool via a HystrixCommand constructor to inject instance specific property overrides.

Enum Summary

HystrixCollapser.Scope	The scope of request collapsing.
HystrixCommandProperties.ExecutionIsolationStrategy	Isolation strategy to use when executing a HystrixCommand.
HystrixEventType	Various states/events that execution can result in or have tracked.
