Abstract
Official abstract text for this publication.
Embodiments of the present invention include systems and methods for insuring better query consistency between at least two different databases, where one faster database has more up-to-date information than another slower database, and wherein updates are typically applied to the faster database first and then to the slower database. In embodiments, the systems and methods also insure that a query to the slower database is not performed until a set of one or more updates from the faster database have been applied to that slower database.
First claim
Opening claim text (preview).
What is claimed is: 1. An in-memory database system that supports fast ingest data transfer between the in-memory database system and a data warehouse system, the in-memory database system comprising: an in-memory database instance configured to receive data events in real-time or near real-time and update the in-memory database instance with the received data events; a listener configured to receive notifications of data events from the in-memory database instance to select a q…
