----------------------------------
Summary: Add an annotation to State to indicate it should always
be fetched
Key: BEAM-9320
URL: https://issues.apache.org/jira/browse/BEAM-9320
Project: Beam
Issue Type: Improvement
Components: sdk-java-core
Reporter: Daniel Mills
Currently, if you have several StateIds that always need to be fetched for a
stateful DoFn, you have to have a block of .readLater() calls at the beginning
of each method. It would be nicer to have an nnotation on the
processElement/processTimer call params to indicate that the value should
always be fetched.
Something like:
@ProcessElement
void process(@RequiredStateId("foo") ValueState foo, E element) \{...}
