---------------------------------------------
Summary: Bring GryoRegistrator to the forefront and deprecate
GryoSerializer
Key: TINKERPOP-1327
URL: https://issues.apache.org/jira/browse/TINKERPOP-1327
Project: TinkerPop
Issue Type: Improvement
Components: hadoop, io
Affects Versions: 3.2.1
Reporter: Marko A. Rodriguez
Fix For: 3.3.0
At the next major release (3.3.0), we should update the documentation and show
the safer model for using Kryo with {{SparkGraphComputer}}.
{code}
spark.serializer=KryoSerializer
spark.kryo.registrator=GryoRegistrator
{code}
{{GryoSerializer}} will simply be deprecated (and thus, backwards compatible).
When deprecating {{GryoSerializer}} we should update the priority for the
{{UnshadedKryoShimService}} as well. Also, in the documentation, we will have
to explain that people should implement {{SerializerShim}} instead of
{{Serializer}} if they want their custom classes to work moving forward. The
change for them is as simple as replacing {{implements Serializer}} with
{{implement SerializerShim}} and handling respective imports.
