Understanding Server Tags

What is a Server Tag?

A server tag is a text string that is associated with a table that is loaded into memory on a SAS LASR Analytic Server instance. The server tag is specified in the LIBNAME statement or as a data set option. The server tag and the table name are used together to match the name used for tables in the SAS LASR Analytic Server.

Why Use a Server Tag?

The following list identifies some reasons for specifying a server tag:

You must use a server tag in a LIBNAME statement or as a data set option to access tables that are loaded from HDFS.
Different users can load tables with the same name, such as Forecast, into a server instance. You use a server tag and the Forecast table name to specify which table to access.
Tables that are loaded into memory with the LASR procedure (but not from HDFS) use the libref as the server tag. In order to access these tables, you must specify the server tag.
When you load a table into memory from HDFS with the LASR procedure, the table is assigned a server tag. The server tag represents the directory path from which the SASHDAT file was loaded. You need to use that server tag to access the table.
