Um estudo de caso sobre uso de processamento de dados distribuídos através do citus

Abstract

Since 2007, the Public Digital Bookkeeping System was implemented in Brazil in private sector companies and also in public government institutions, which are responsible for the supervision and control of such activities as city and state tax authorities and the Federal Revenue Service itself. At this context, although the agility in the monitoring of tax authorities and economy, the large volume of data stored from electronic invoices has driven the demand for the development of new technologies for analysis and monitoring in an efficient manner. Thus, the present work conducted a study to evaluate the performance of query execution time in Citus in comparison with PostgreSQL.
