They can scale up to 2048 Nodes. The major components of Teradata are Parsing Engine, BYNET and Access Module Processors (AMPs). The big advantage Teradata has over other database systems is that its high level of parallelism was part of the Teradata architecture from the start many years ago (when most of its components were implemented in hardware instead of software) In the course of time, even new features have been made possible in order to further increase parallelism. Die wichtigsten Mitbewerber sind andere High-End-Hersteller wie IBM mit dem RDBMS DB2, Oracle mit dem gleichnamigen RDBMS und der Appliance EXAdata sowie Exasol mit dem gleichnamigen Produkt. Teradata Architecture:-To know more about various Teradata we would first need to understand the architecture of Teradata. VARCHAR DirectoryPath = @jobvar_datafiles_path. Teradata Nodes, its Access Module Processors (AMPs) and the disks associated with AMPs work independently. I wonder does this data cause connection timeout? ('DROP TABLE ' || @jobvar_tgt_dbname || '.Trans;'). Teradata Architecture 1. In this case the number of AMPs is few. Access Module Processors (AMPs) BYNETs. Teradata provides two products.
