Hi all,
I’m currently working on enhancing a Beam test suite to check compatibility
with Java 11 UDFs. As JDK11 introduces several useful features, I wanted to
turn to the Devlist to gather your opinions on which features should be
included in the DoFn.
To give you an idea of how the test will be designed, I’m planning to
create a test pipeline with a custom DoFn which will use JDK11 specific
features. This test will be compiled with JDK11 and ran using a binary of
Beam built with JDK8 in order to simulate a situation in which the user
downloads the Beam from Maven repository and uses it in their project built
in Java 11.
The features I believe are worth checking are:
-
String manipulation methods:
-
.repeat
-
stripTrailing, stripLeading and strip()
-
isBlank
-
Lines
-
RegEx asMatchPredicate
-
Local parameter type inference in lambda expressions
-
Optional::isEmpty
-
Collection::toArray
-
Path API change - Path::of
I don’t think that checking other new features in Java 11 such as flight
recording or new HTTP client which we probably won’t use in Beam is
justified, but I’m open to suggestions and discussion.
Which of those new features should be included in the DoFn applied in the
test?
I will be grateful for any input.
Have a good day
Michal
