camundas DecisionService#evaluateDecistionTable returns an EveluationResult which basically (depending on the hit policy) returns a key/value map of output columns (or list of map).

Using jackson, it is easily possible to automatically transform these to data objects. This would allow easier access to the result and handling of missing values.

Current usage:

VariableMap map = Variables.createVariables();
VariableReadWriteAdapter adapter = VariableReadWriteAdapter.of(map);

adapter.write(FOO, "foo")

// now map contains "foo"

desired:

VariableMap map = VariableReadWriteAdapter.map()
    .write(FOO, "foo")
    .getMap();

All dependencies and versions should be managed by a gradle java-platform project.

Camunda does not provide a BOM for spring boot components, so we could offer an (oppinionated) BOM that provides:

• SpringBoot
• Camunda
• Camunda-Spring Boot
  -these addons

it's a separate project: https://github.com/holunda-io/camunda-bpm-data

addon ideas that are not yet "production ready" should reside in an incubator space

If a variable requires a specific read/write converter, this might not necessarily be available from a static context (objectMapper, mapstruct, ...)
To support those cases it should be possible to define an empty variable definition and register it to a context at runtime

5.3.1 by now

provide simplified, jackson based, custom jobs

By automatically converting Date to LocalDate/LocalTime

addons are written in kotlin, but we have to make sure they can beu easily used from java code

Once we created a variableReadWriteAdapter, it would be nice to reuse it in a fluent way.

so instead of

VariableReadWriteAdapter adapter = VariableReadWriteAdapter.of(delegateExecution);
adapter.write(FOO, "foo");
adapter.write(BAR, "bar");

support

VariableReadWriteAdapter adapter = VariableReadWriteAdapter
     .of(delegateExecution)
    .write(FOO, "foo")
    .write(BAR, "bar");
