-----------------------------------
Summary: Decouple Topology Definition from Java Code
Key: STORM-3860
URL: https://issues.apache.org/jira/browse/STORM-3860
Project: Apache Storm
Issue Type: Task
Reporter: Bipin Prasad
Current Topology definition is tightly integrated with Java code. Even though
the topology definition is defined in thrift, the Java class itself is
serialized at the ComponentObject level as a binary serialized java object.
If the ComponentObject contains, two fields:
- type of Component (shell or java..) - string
- name of class - string
then the topology definition can be decoupled from Java code (and serialization
requirement). The topology can be displayed directly from the definition. And
the definition can be created via other visualization tools.
Jars used by the topology can be part of deployment rather than topology
definition.
In future, the same topology definition can be deployed in a different way, in
a different environment (i.e. Kubernetes) in a much lightweight manner to
achieve higher throughput per megabyte CPU.
