------------------------------
Summary: Serialization of spouts/bolts
Key: STORM-168
URL: https://issues.apache.org/jira/browse/STORM-168
Project: Apache Storm (Incubating)
Issue Type: New Feature
Reporter: James Xu
Priority: Minor
https://github.com/nathanmarz/storm/issues/367
Once annoying thing about Java serialization is that it requires all
serializable objects to be explicitly marked with Serializable interface. When
using 3rd party libraries, sometimes people forget to do this. An idea here is
to use Kryo serialization instead and have it default to Java serialization.
The serializer should be prepped with the same serializers as is used for the
Kryo serializer for tuples in the topology.
----------
RomezzBorisov: It should be possible to choose the s11n approach via
configuration
----------
danehammer: @nathanmarz Can you explain further? Would this be implementing a
spout serializer? A bolt serializer?
----------
RomezzBorisov: It should be possible to provide a custom s11n for Storm objects
in topology (bolts and spouts both, I don't think it's necessary to distinguish
them) via implementing smth like StormSystemSerializer interface.
The instance of serializer should be passed to topology builder.
There should be several default implementations like JavaSystemSerializer,
KryoSystemSerializer e.t.c.
