What’s New In SAS LASR Analytic Server

Overview

SAS LASR Analytic Server 2.2 includes the following changes:
  • Enhancements to the IMSTAT procedure
  • The IMXFER procedure
  • Enhancements to the SAS LASR Analytic Server engine
  • Enhancements to the SAS Data in HDFS engine
  • Limited DATA step programs can run in memory for scoring.
  • Documentation enhancements

Enhancements to the IMSTAT Procedure

The IMSTAT procedure has the following enhancements:
  • The SCHEMA statement can be used to join in-memory tables.
  • The SET statement can be used to append entire in-memory tables to another in-memory table.
  • The LIFETIME and PURGETEMPTABLES statements can be used to manage (and conserve) memory.

IMXFER Procedure

The IMXFER procedure is a new procedure that enables you to transfer in-memory tables from a distributed SAS LASR Analytic Server to another. The servers can be on the same cluster or different clusters. The number of machines in each cluster can be different.
The procedure works with distributed servers only.

Enhancements to the SAS LASR Analytic Server engine

The engine has the following enhancements:
  • The VERBOSE= option is added. This option can be used to request more details for error messages related to connection problems.
  • The AUTOCOMMIT= option is added. This option enables you to control how the server commits rows during append operations.
  • The TEMPNAMES= option is enhanced to enable you to specify whether a variable is a numeric or character data type. For character data types, you can also specify the variable length.

Enhancements to the SAS Data in HDFS engine

The VERBOSE= option is added. This option is identical to the SAS LASR Analytic Server engine and can be used to help diagnose connection problems.

Support for DATA Step Programming for Scoring in SAS LASR Analytic Server

The DATA step is enhanced to support running in-memory for scoring. The DSACCEL=ANY SAS system option must be set. A subset of the DATA step syntax can be passed through to the server for parallel execution. Information about how to enable the feature and the limitations are provided in Programming with SAS LASR Analytic Server.

Documentation Enhancements

The language element reference information for the HPDS2 procedure is removed. The reference information is available in the Base SAS Procedures Guide: High-Performance Procedures.
SAS LASR Analytic Server: Reference Guide is a new document that covers administration and programming information for SAS LASR Analytic Server.
The SAS LASR Analytic Server: Administration Guide is not published for this release.
