SAS Visual Analytics
can load data from registered tables or from SASHDAT files stored
in HDFS to the SAS LASR Analytic Server.
The following table identifies some of the advantages and disadvantages
of each method:

|
Provides a rapid method
for loading tables.
|
Appropriate for smaller
data sets because the data must be transferred over the network.
If the table is unloaded
or the server stops, the data must be transferred over the network
again.
|
|
|
Impressive performance
for loading very large data sets in parallel.
If a SAS LASR Analytic Server
is stopped or the table is unloaded from the server, loading it again
is also very fast.
|
Requires a separate
step to add the data to HDFS and then load it before the data is available
to SAS clients.
