Incrementally maintaining materialized temporal views in column-oriented NOSQL databases with partial deltas

Abstract

Different from the relational database systems, each column in a column-oriented NoSQL database (CoNoSQLDB) maintains multiple data versions in which each data version is attached with an explicit timestamp (TS). In this paper, we study how to maintain the materialized temporal views (MTVs) in CoNoSQLDBs with partial temporal data-changes (deltas). We first review our previous work and indicate that not all change-data capture (CDC) approaches are able to provide complete deltas. Then, we propose approaches for maintaining MTVs with partial deltas.
