What's New in SAS Federation Server
Overview
The following new features
have been added to SAS Federation Server 4.2:
-
SAS Federation Server connectivity
to SAS Scalable Performance Data Server (SPDS) allowing READ, WRITE,
and UPDATE to SPDS tables.
-
replacement of DataFlux Authentication Server by SAS Metadata Server for
authentication and other permission-based functions
-
support for SAS DS2 model scoring
code in your database
-
-
cache enhancements that include cache refresh for data held in memory (
MDS)
-
embedded data quality and cleansing
functions in data views
-
Read/Write access to Hadoop (HIVE)
using the SAS Federation Server Driver for Apache Hive
-
new SAS Federation Server
driver that allows shared data sources across multiple SAS Federation Servers
SAS Federation Server Driver for SPD Server
Tables located on SAS
SPD Server can be accessed for reading, writing, and update by SAS
Federation Server with the SAS Federation Server Driver for SPD Server
(Driver for SPD Server). The Driver for SPD Server provides connectivity
from a SAS Federation Server on any host to an SPD server running
anywhere. The Driver for SPD Server integrates with UNIX hosts as
well as Windows. See
SAS Federation Server Driver for SAS Scalable Performance Data (SPD) Server .
SAS Metadata Server
SAS Metadata Server replaces DataFlux Authentication Server as the authentication
provider. SAS Metadata Server provides access for user and group objects, as well
as other permission-based functions such as shared logins and trusted users. SAS Federation
Server objects are populated from objects created in SAS Metadata Server. There is
no longer a need to create federation server objects in SAS Federation Server Manager.
See the SAS
Federation Server: Administrator’s Guide for information
about how SAS Federation Server works with SAS Metadata Server.
SAS DS2 Language Support
DS2 is a SAS proprietary programming language that is used for advanced data manipulation.
DS2 provides capabilities not available through
SQL, such as scoring models. You can also use DS2 code to run data quality functions
using SAS Federation Server Manager.
New Data Masking Rules
New data masking features
include TRANC, which transliterates characters from the input string
to characters in the output string. A series of random data masking
rules are also available. See the
Data Masking Rule Types and Arguments for information about each of these new rules and their
functionality in SAS Federation Server Manager.
Enhanced Cache Operations
Federation Server now has the capability of refreshing cached data in MDS after a
server restart. In previous releases, cached data that was held in memory
was deleted if the server was restarted or shut down. Now the cache held in memory
is retained and refreshed at server restart by default. See the SET RESTART='REFRESH'
option in the CREATE CACHE statement for details. Also see “Data Caching” for additional
information about creating a cache table.
Data Quality and Cleansing
The new data quality
and cleansing is implemented using SAS Quality Knowledge Base (QKB)
with FedSQL and DS2. The data quality methods use data quality rules
from the SAS QKB in order to cleanse data. The SAS Quality Knowledge
Base (QKB) is a collection of files that store data and logic that
define data management operations such as parsing, standardization,
and matching. SAS software products refer to the QKB when performing
data management operations, also referred to as data cleansing, on
your data. See “Data Quality for SAS Federation Server”
for additional information.
SAS Federation Server Driver for Apache Hive
SAS Federation Server
supports big data with the SAS Federation Server Driver for Apache
Hive (Driver for Hive). The Driver for Hive enables SAS Federation
Server to query and manage large data sets that reside in distributed
storage. The Driver for Hive supports multiple versions of Hadoop.
See
About the SAS Federation Server Driver for Apache Hive. for additional information including configuration and
connection options.
SAS Federation Server Driver
You can now share data sources across multiple SAS Federation Servers with the new
federation server driver (FEDSVR). The driver enables you to define a connection from
one SAS Federation Server
to another SAS Federation Server. This connectivity can be useful for distributing
work load or to federate data between various federation servers. See “About the Federation
Server Driver” for additional information including configuration and connection options.
