SAS Visual Analytics can
load tables into memory on a SAS LASR Analytic Server from
a table that is registered in SAS metadata. If the table is from a
DBMS library that is co-located with the SAS LASR Analytic Server
instance, then the server instance recognizes that the table is from
a co-located data provider and reads the data into memory in parallel.
If the table is not from a co-located data provider (for example,
a SAS data set), then the table is read from the data source, transferred
to the root node on the cluster, distributed to the machines on the
cluster, and then loaded into memory.
To load from a table:
-
Locate the table using
the SAS Folders view or by searching. Right-click the table icon and
select
Load from Table.
-
On the
General page,
specify values for the
Job name,
Location,
and
Description if you intend to save this
action as a job.
-
Select the
Settings page
and specify the SAS LASR Analytic Server and data parameters:
|
|
|
This field specifies
the location of the server description files.
|
|
This field specifies
the name of the server description file.
|
|
The table name is populated
automatically.
|
|
Specify a description
for the data. This description overrides the description that is
stored with the table. The description is displayed beside the table
name in the explorer interface.

-
The following items
provide additional information about loading from a table:
-
The table to use as the data source
must be registered in metadata before you can perform this task.
-
For deployments that use a co-located data provider, the SAS LASR Analytic Server
performs a comparison of IP address to determine whether a parallel
read is possible. The IP address that is in the SERVER= option of
the generated LIBNAME statement must match the IP address of the SAS LASR Analytic Server
root node.
-
When the data is loaded from a
data source that is not a co-located data provider, it is transferred
to the root node of the server, distributed evenly among the machines
in the cluster, and then loaded into memory.
