KieSession.insert() 和 KieSession.fireAllRules() 是线程安全的吗？
Is KieSession.insert() and KieSession.fireAllRules() thread-safe?
我正在使用 Drools 和 Spring Boot。在我的项目中，我正在制作 KieSession、KieContainer 和 KieServices 的单例 Bean。 KieSession 将用于不同的单例服务和控制器。我想知道 KieSesion.insert() 和 KieSession.fireAllRules() 是否是 线程安全的 单例 bean 实现。或者我应该创建一个实用程序 class 具有 synchronized 访问 KieSesion.insert() 和 KieSession.fireAllRules()?
KieSession 自 Drools 6 以来一直是线程安全的，从 manual
Engine’s code dealing with multi-threading has been partially
rewritten in order to remove a large number of synchronisation points
and improve stability and predictability. In particular this new
implementation allows a clearer separation and better interaction
between the User thread (performing the insert/update/delete actions
on the session), the Drools engine thread (doing the proper rules
evaluation) and the Timer one (performing time-based actions like
events expiration).
自 7.52.0.Final 起，如果不需要获得一些性能，用户可以禁用线程安全。这是 relevant 发行说明：
As per the default configuration, a KieSession is thread-safe and can
be shared safely and used by multiple threads at the same time.
However, if a KieSession is running, it requires additional
synchronization points to support the thread-safety, which is not
required, and eventually, it slows the performance of the KieSession.
Therefore, a new ThreadSafeOption is introduced, which you can use to
optionally disable the thread-safety. The ThreadSafeOption consists of
two values including YES (default) and NO.
