Open-source Hadoop software developed by the Apache Software Foundation (ASF).
cache access application for update
Application for storing initial data and updating data in a cache in an XTP Server.
CEP (Complex Event Processing)
Refer to "complex event processing".
Refer to "high-performance CEP engine".
Service that runs on the CEP Server and manages the CEP engine.
Technique of rapidly analyzing, assessing and processing in real time the content and status of massive volumes of event data being sent continuously.
It is used in the complex event processing feature provided by this product.
complex event processing language
Language for specifying the rules of complex event processing.
It allows the use of SQL format.
Rule described using the complex event processing language, consisting of at least one complex event processing statement.
complex event processing statement
Structural unit of rules specified using the complex event processing language.
A complex event processing statement describes processing using statements such as the SELECT statement and the CREATE WINDOW statement.
Feature that outputs debug messages to the engine log when a complex event processing statement is executed.
User of the operating system when a CEP engine is running.
File containing the output of CEP engine system messages and debug messages defined in the rules.
Time-series data, such as sensing data or location information about people, and that shows when something occurred.
File containing event data which is recorded by logging.
event log analysis application
Application that analyzes event logs in the Hadoop system.
Application that sends event data to a CEP engine.
Definition information about the format of event data.
The event data can be specified in XML or CSV format.
Refer to "high-speed filter language".
Refer to "high-speed filter rule".
Refer to "high-speed filter statement".
Technique for effectively performing distributed and parallel processing of data accumulated in massive volumes. It basically consists of the HDFS (Hadoop Distributed File System) and the MapReduce which is known as a parallel distributed processing technique.
Refer to "Apache Hadoop".
In logging context, a feature for recording event data from the CEP Server directly in the Hadoop system.
System on which Hadoop is running.
HDFS (Hadoop Distributed File System)
Distributed file system used by Hadoop.
For the placement of big data, HDFS creates multiple replicas of data blocks and distributes them on nodes called DataNodes, which are then managed by nodes called NameNodes.
The processing unit in this product.
It allows massive volumes of event data to be processed rapidly by combining the high-speed filter with conventional complex event processing.
Feature that uses a technique unique to Fujitsu to allow high-speed filtering of massive volumes of event data while matching the event data with the master data.
Language for specifying the rules in the high-speed filter.
It allows the use of IF-THEN format.
Rule described using the high-speed filter language, consisting of at least one high-speed filter statement.
Structural unit of rules specified using the high-speed filter language.
A high-speed filter statement is described for each event type definition.
input adapter that allows event data to be received using HTTP communication.
It allows more lightweight communication when compared to a SOAP adapter.
CEP engine created at installation.
Feature that receives event data from outside the CEP Server.
Feature that records event data in a Hadoop system or in the engine log.
Feature that logging the processing results of a complex event processing statement.
Data used by this product to match event data in high-speed filter processing.
It is deployed in the CEP Server in CSV format, and consists of schema files (where the item names for each column are defined), and data files (where the data rows are stored).
Definition information of the master data to be referenced during high-speed filter processing.
Feature that sends the processing results of complex event processing outside the CEP Server.
Log containing the resource usage of a CEP engine.
It is stored in CSV format, so it can be analyzed using a tool such as Excel.
Processing details for the high-speed filter (high-speed filter rule) and complex event processing (complex event processing rule) features.
Data sent from a variety of sensors.
Sensing data is a type of event data.
SOAP (Simple Object Access Protocol)
Lightweight protocol, which is subject to ongoing standardization work by the World Wide Web Consortium (W3C).
For its communication infrastructure, SOAP uses the Internet standards of Hyper Text Transfer Protocol (HTTP) and (eXtensible Markup Language (XML).
input adapter that allows event data to be received using SOAP.
Feature that uses SOAP to send the processing results of a complex event processing statement to an external system.
Defines information required to perform communication using a SOAP listener.
It defines information such as the URL of the external system that is to be the communication target.
Services and applications that provide open communication generated by diverse content (such as text, voice and video) exchanged and shared on the Internet by a variety of people, in contrast to the traditional information media (such as newspapers and television).
input adapter that performs communication using a format unique to this product.
Socket adapters are more suitable for receiving massive volumes of event data than a SOAP adapter or HTTP adapter.
Application that uses SOAP to receive processing results of a complex event processing statement sent from a SOAP listener.
WSDL (Web Services Description Language)
Interface description language in Web services, which allows the description of information such as the access point in Web services (URL), the protocol to be used (SOAP, HTTP, or MIME), and the message format (XML Schema).
It is used in the development of a user-developed Web service, which is an application for collaborating with this product.
In complex event processing for this product, a feature for referencing the cache of an XTP Server outside the CEP Server.
XTP collaboration is used to reference frequently updated data from a complex event processing rule.
