Manu Zhang updated GEARPUMP-111:
--------------------------------
Description:
In Stream DSL, all broadcasting chained operations will be translated to
individual tasks.
For example,
{code}
val stream = StreamApp.source(source, 1, "source")
stream.filter(fn, "filter A")
stream.filter(fn, "filter B")
stream.filter(fn, "filter C")
{code}
This will be translated to 1 SourceTask and 3 FilterTasks although it's
possible for them to be done in 1 Task.
was:
In Stream DSL, all broadcasting slave operations tailing a master operation
will be translated to individual tasks.
For example,
{code}
val stream = StreamApp.source(source, 1, "source")
stream.filter(fn, "filter A")
stream.filter(fn, "filter B")
stream.filter(fn, "filter C")
{code}
This will be translated to 1 SourceTask and 3 FilterTasks although it's
possible for them to be done in 1 Task.
