It is used to transfer data between parsing engine (PE) and access module processor (AMP). These refer to virtual processors or VProcs. DEFINITION PE, acronym for "Parsing Engine," is the type of vproc (Virtual Processor) for session control, task dispatching and SQL parsing in the multi-tasking and possibly parallel-processing environment of the Teradata Database. Give some of the primary characteristics of the same. Question 105. AMP (Access Module Processor) is virtual processor which is responsible for parallelism in Teradata and each AMP is associated with a virtual disk which is subset of physical disk. Message Passing Layer − Message Passing Layer called as BYNET, is the networking layer in Teradata system. It provides up to 1 terabyte of storage. It receives the execution plan from Parsing Engine and sends to AMP. It is a way to logically look at hardware resources so that the actual details of the hardware pieces are abstracted or generalized. When the client runs queries to insert records, Parsing engine sends the records to BYNET. The Main component of teradata are given below : Parsing Engine aka PE Access module processor aka AMP Bynet Vdisk Parsing Engine : This is the manager , PE Knows every thing… Each optimized query step is sent as a message from the parsing engine (the virtual processor that performs optimization) to the AMPs (the virtual processors that execute the step in parallel), usually one step at a time. A few of them are widely used and play a significant role in making the tasks simple are spotlighted below. The Teradata RDBMS for UNIX is classified as a TPA. I am Rinki, having an overall experience of 8+ years ,all in Teradata. Virtual Disk is basically a compilation of a whole array of cylinders which are physical disks. multicore chips; see the processor metric definition on the price list), would require 8 * 0.5 = 4 processor licenses (each virtual core is considered equivalent to a physical core).” Bear in mind that for AWS at least, 4 vCPU = 2 Hyper-Threaded cores = 1 Oracle processor (following the Virtual Core table here) – Teradata 14.0 introduces Teradata Columnar – a new approach for organizing the data of a user-defined table or join index on disk. The responsibilities of parsing engine are −, Parse the SQL query check for syntax errors, Check if the user has required privilege against the objects used in the SQL query, Check if the objects used in the SQL actually exists, Prepare the execution plan to execute the SQL query and pass it to BYNET, Receives the results from the AMPs and send to the client.
