The High-Performance
Analytics transformations in SAS Data Integration Studio use the OLIPHANT
procedure and the LASR procedure, which are part of SAS LASR Analytic
Server.
The SAS LASR Analytic
Server is an analytic platform that provides a secure, multi-user
environment for concurrent access to data that is loaded into memory.
The server can take advantage of a distributed computing environment
by distributing data and the workload among multiple machines and
performing massively parallel processing. The server can also be deployed
on a single machine where the workload and data volumes do not demand
a distributed computing environment.
For distributed deployments,
having local storage available on machines is critical in order to
store large data sets in a distributed form. The SAS LASR Analytic
Server supports HDFS as a co-located data provider. HDFS is used because
the server can read from and write to HDFS in parallel. In addition,
HDFS provides replication for data redundancy. HDFS stores data as
blocks in distributed form on the blades and the replication provides
failover capabilities.
