In this release, the Get and Set modules have been replaced by
GetLocal/SetLocal and GetGlobal/SetGlobal. Briefly, the difference
between these pairs of modules is that the Global pair maintains state
between executions, while the Local pair do not. (Remember that a single
loop in the visual program is considered a single execution). If you do
not do anything to modify your visual program, any Get/Set pairs which
you have will be replaced by GetGlobal and SetGlobal, and the visual
program will run as it did before. However, in many cases you can
replace your Get/Set pair by GetLocal and SetLocal for performance
advantages. One way to know if you can do this is if you are using the
First module to reset Get on each execution. If so, then you can
certainly replace your Get and Set by GetLocal and SetLocal (and the
First module is no longer necessary, as GetLocal automatically resets on
each new execution).
See GetLocal, SetLocal, GetGlobal,
and SetGlobal in IBM Visualization Data
Explorer User's Reference for more detailed information.
