Embodiment Construction

[0054] In the following description, various embodiments will be described. For purposes of explanation, specific configurations and details are set forth in order to provide a thorough understanding of the embodiments. It will be apparent, however, to one skilled in the art that the embodiments may be practiced without these specific details. Furthermore, well-known features may be omitted or simplified in order to avoid obscuring the described embodiments.

[0055] In some applications, data can take the form of a continuous unbounded stream rather than a finite set of stored data. Examples of such data streams can include stock ticks in financial applications, performance measurements in network monitoring and traffic management, logging or clickstreams for web tracking and personalization, data feeds from sensor applications, firewall-based Network packets and messages in security, call detail records in telecommunications, and more. Due to their sequential nature, thes...

Abstract

Techniques for managing value-based windows on relations are provided. In some examples, an input relation is generated. The input relation is a bounded set of data records related to an application. A continuous query that identifies the input relation may be received. Additionally, a configurable window operator associated with processing the input relation may be identified. Then, the continuous query may be executed based at least in part on the configurable window operator to generate an output relation. Further, in some instances, the data records of the output relation may be provided based at least in part on execution of the continuous query.

Description

Background technique [0001] In traditional database technology, data is usually stored in one or more databases in the form of tables. The stored data is then queried and manipulated using a data management language such as Structured Query Language (SQL). For example, SQL queries can be defined and executed to identify relevant data from data stored in a database. Hence, SQL queries are executed on a limited set of data stored in the database. Additionally, when a SQL query is executed, it is executed once on a finite set of data and produces finite static results. Therefore, databases are best equipped to operate on finitely stored data sets. [0002] However, many modern applications and systems generate data as continuous streams of data or events rather than finite data sets. Examples of such applications include, but are not limited to, sensor data applications, financial tickers, network performance measurement tools (eg, network monitoring and traffic management ap...
