difficult to meet the requirements of real-time analysis of risk events.2), Memory Database scheme: Because of the huge transaction data query, analysis consumes the database resource extremely, may use the memory database scheme to replace the relational database, guarantees the risk event real-time processing performance. But currently open source memory data in Voltdb, H2, MonetDB, Fastdb, Berkeley DB, SQLite in large-scale business applications of the maturity of the application is yet to b

Coordinator is stateless and can be used to process simple events and complex events. However, they do not combine their own new complex events, that is, event Coordinator cannot combine simple events (that is, aggregation) as complex events, mainly because they cannot be maintained. Generally, only one event stream or channel can be input, but multiple event streams or channels can be output. This example includes an integrated proxy.Complex Event Processing (

15.6.8. Permission Authorization Model To solve the application permissions. Seam Security provides a scalable framework. The following class diagram provides an overview of the main components of the permission framework: The related classes will be explained in detail in the following sections.15.6.8.1. PermissionResolver This is actually an interface that provides a solution to the permissions of individual objects. Seam provides the following built-inPermissionResolverImplementation: RuleB

Hara CoffeeonesugarTranslation: Liu BinhuaIn my previous post, I mentioned my recent passion for complex event processing (CEP) (complex incident handling). In short, the CEP takes the data stream as input, redirecting the data (or part of the data) to the listener based on a set of predefined rules, or triggering an event when the implied patterns (pattern) are found in the data.

In short, CEP uses data streams as input and redirects data (or part of data) to listeners based on a series of predefined rules, or Pattern in data discovery).

is to add a filter to the task instance: simply open the hibernate file of the task instance and add some hibernate filters: Note that the parameter passed to the filter starts with ":", and other fields (such as _ id) belong to taskinstance. Then, when you fill your database, make the selected filter take effect: String SQL = "from org.jbpm.taskmgmt.exe. taskinstance "; String sql = "from org.jbpm.taskmgmt.exe.TaskInstance";session.enableFilter("filterPriority").setParameter("paramPrior

However, if you want to specify that all versions above a certain version support how to specify? For example, to support more than 2014 Premierepro CC, how t

Due to the need for work, I began to learn drools, based on the introduction of the official website in Eclipse built the drools development environment.Environment: MacOS10.10 + EclipselunaDrools Version: DROOLS61.

a literal condition. When a rule has more than one literal condition for an object type, these literal conditions are linked together. This is to say that if an application asserts an account object, it must first satisfy the first literal condition before it can reach the next alphanode. In Dr. In Forgy's paper, he uses intraelement conditions to express. The following illustration shows the alphanode combination of cheese (name = = "Cheddar", strength = = "Strong"):

Allow out-opt from offset committing for the Kafka consumer: By default, Kafka commits the offsets to the Kafka b Roker once a checkpoint has been completed. This change allows the users to disable this mechanism (FLINK-3398). CEP LibraryThe CEP library has been greatly enhanced and are now able to accommodate more use-cases Out-of-the-box (ex

executing the rule and other actions. the inference (rule) engine of RBEs corresponds to human thinking. The rule engine has two ways of reasoning: Forward-chaining) and induction (backward-chaining ). The explain method starts from an initial fact and constantly applies rules to draw conclusions (or execute specified actions ). The induction rule is to start from assumptions and constantly look for facts that conform to the assumptions. rete algorithm is currently the most efficient fo
