The +first difference is that weâve not focused on performance at all. For +some reason other implementations make a point about doing "atomic +changes" with various tricks, to ensure good performance. Since this is +used to guard access to external systems, where latencies range in +milliseconds and up, that seems completely useless, so weâve just put +"synchronized" on all methods, which should be safe. "It works" is +better than "itâs fast" for these types of things.</p><p>Second, other implementations have had really crude logic for what types +of exceptions cause the circuit to break. The most crude is "all", more +advanced ones allow exceptions that be excepted to be registered, but in +real cases this is not enough. Case in point is JDBC exceptions where +you want to fail on "connect exception" but not necessarily "invalid SQL +syntax". So instead weâve leveraged <code class="literal">Predicate</code> where +you get to provide your own specification that can use any logic to +determine whether a particular exception is ok or not.</p><p>Third, thereâs a big focus on manageability through JMX. A +circuitbreaker can be easily exposed in JMX as an MBean, where you can +track service levels and see exception messages, and trip/enable circuit +breakers.</p><p>Fourth, if an external system is unavailable due to a circuitbreaker +tripping it should be possible to expose this to other Polygene⢠services. +There is a standard implementation of the Availability interface that +delegates to a circuit breaker and the Enabled configuration flag, which +is what weâd suspect will be used in most cases where external systems +are invoked.</p><div class="table"><a id="idm4406"></a><p class="title"><strong>Table 24. Artifact</strong></p><div class="table-contents"><table summary="Artifact" border="1"><colgroup><col class="col_1" /><col class="col_2" /><col class="col_3" /></colgroup><thead><tr><th align="left" valign="top">Group ID</th><th align="left" valign="top">Artifact ID</th><th align="left" valign="top">Version</th></tr></thead><tbody><tr><td align="left" valign="top"><p>org.apache.polygene.libraries</p></td><td align="left" valign="top"><p>org.apache.polygene.library.circuitbreaker</p></td><td align="left" valign="top"><p>0</p></td></tr></tbody></table></div></div><br class="table-break" /><div class="section"><div class="titlepage"><div><div><h4 class="title"><a id="_direct_usage"></a>Direct usage</h4></div></div></div><p>The CircuitBreaker can be used directly, even without using anything else from the Polygene⢠SDK.</p><p>Here is a code snippet that demonstrate how to create a CircuitBreaker and how it behave:</p><pre class="programlisting brush: java">// Create a CircuitBreaker with a threshold of 3, a 250ms timeout, allowing IllegalArgumentExceptions +CircuitBreaker cb = new CircuitBreaker( 3, 250, CircuitBreakers.in( IllegalArgumentException.class ) ); + + [...snip...] + +// Service levels goes down but does not cause a trip +cb.throwable( new IOException() ); + + [...snip...] + +// Service level goes down and causes a trip +cb.throwable( new IOException() ); +cb.throwable( new IOException() ); + + [...snip...] + +// Turn on the CB again +cb.turnOn(); + + [...snip...] + +// Service levels goes down and causes a trip +cb.throwable( new IOException() ); +cb.throwable( new IOException() ); +cb.throwable( new IOException() ); + + [...snip...] + +// Wait until timeout + + [...snip...] + +// CircuitBreaker is back on + +</pre></div><div class="section"><div class="titlepage"><div><div><h4 class="title"><a id="_service_circuit_breaker"></a>Service Circuit Breaker</h4></div></div></div><p>As a facility you can make your Services extends <code class="literal">AbstractBreakOnThrowable</code>, set them a <code class="literal">CircuitBreaker</code> as +<code class="literal">MetaInfo</code> during assembly and annotate methods with <code class="literal">@BreaksCircuitOnThrowable</code>.
