The three key modules are query optimizer, execution engine, and storage engine. Among them, the role of execution engine to the DBMS is like the chef to a restaurant. This article focuses on the execution engine of theApache Dorisdata warehouse, explaining the secret to its high performance....
The query processing system stores actual cardinality values determined during the execution of the logical steps in the database catalog for use by subsequent queries. The query processing device therefore re-uses previously-determined cardinality values.GHAZAL, AHMAD...
In Stream 2, the query runs a network operation in Segment 4 and Segment 5 to send intermediate results to the leader node for further processing. The last segment of a query returns the data. If the return set is aggregated or sorted, the compute nodes each send their piece of the inte...
Business process integration (BPI) is necessary to take full advantage of advances in data analytics, generative AI (GenAI), automation with AI-powered agents (agentic AI), and natural language processing. There are several methods for connecting applications and data sources, including the native ...
While the advantages are obvious, edge computing systems come with many of the same requirements for physical and cybersecurity and fault tolerance that are faced in larger data centers. Micro data centers are self-contained systems that bring processing power closer to the end user or device to...
