URL: https://github.com/apache/beam/pull/12704
Change-Id: I660b98ac7cd562eb03aab6d15d829eae8726ebad
The following API changes the way that the Interactive Runner caches
data from unbounded sources. Previously, a user-configurable duration
would run a "Background Caching Job" that would cache all elements from
unbounded source. Then, the user pipeline would run by reading from
that cache after completion. Now, there is a long lived "Background
Recording Job". This replaces the caching job with a background pipeline
that records elements from the unbounded sources and most importantly
does not block user pipeline execution.
The following APIs have changed:
show(*pcolls, include_window_info=False, visualize_data=False) -->
show(*pcolls, n='inf', duration='inf', include_window_info=False,
visualize_data=False)
The show() command was modified to include a max number of elements and
a max duration of elements to read. The show() command will end when
either of the limiters gets triggered, whichever comes first. If a
limiter is not supplied it is assumed to be infinite. For example,
show(pcoll, n=5000) will read and block until 5000 elements are read.
collect(pcoll, include_window_info=False) -->
collect(pcoll, n='inf', duration='inf', include_window_info=False)
The collect() command was modified to include a max number of elements and
a max duration of elements to read. The collect() command will end when
either of the limiters gets triggered, whichever comes first. If a
limiter is not supplied it is assumed to be infinite. For example,
show(pcoll, n=5000) will read and block until 5000 elements are read.
head() was removed.
