Features Of Datastage:
There are 5 important features of DataStage, they are
- Any to Any,
- Plat form Independent,
- Node configuration,
- Partition parallelism, and
- Pipe line parallelism.
Any to Any:
Data stage can Extarct data from any source and can load data in to any target
Platform Independent:
A job can run in any processor is called platform independent
Data stage jobs can run on 3 types of processors
Three types of processor are there, they are
1. UNI Processor
2. Symmetric Multi Processor (SMP ), and
3. Massively Multi Processor (MMP).
Node Configuration:
Node is a logical CPU ie.instance of physical CPU
The process of creating virtual CPU’s is called Node configuration
Example:
ETL job requires executing 1000 records
In Uni processor it takes 10 mins to execute 1000 records
But in same thing SMP processor takes 2.5 mins to execute 1000 records
