--------------------------------------
Summary: Allow OperatorTransformation to bootstrapWith a Scala
DataSet
Key: FLINK-17445
URL: https://issues.apache.org/jira/browse/FLINK-17445
Project: Flink
Issue Type: Improvement
Components: API / State Processor
Affects Versions: 1.10.0, 1.11.0
Reporter: Brandon Bevans
Currently there is no way to use OperatorTransformation.bootstrapWith using a
Scala DataSet. The functionality does seem to be there since a Scala DataSet
appears to just be a wrapped Java DataSet. This functionality could be achieved
with minimal invasiveness by passing through the underlying Java DataSet to the
call.
Also, the docs suggest that this function should work:
From
[https://ci.apache.org/projects/flink/flink-docs-stable/dev/libs/state_processor_api.html]:
{code:java}
val currencyDataSet = bEnv.fromCollection(CurrencyRate("USD", 1.0),
CurrencyRate("EUR", 1.3)) val broadcastTransformation = OperatorTransformation
.bootstrapWith(currencyDataSet) .transform(new CurrencyBootstrapFunction){code}
I would love to take this issue on.
