Sandesh created APEXCORE-478:
--------------------------------
Summary: SerDe based on the types
Key: APEXCORE-478
URL: https://issues.apache.org/jira/browse/APEXCORE-478
Project: Apache Apex Core
Issue Type: Improvement
Reporter: Sandesh
During deploy time, Apex already knows the type of the object to be serialized
and deserialized. I am quoting Vlad here,
"
+1 for type based serialization. Tuples in most cases are flat
records/pojo and it should be possible programmatically construct a
codec that will significantly outperform Kryo. It should also reduce
amount of data passed over the wire. I started to look in that direction
as well as Kryo serialization is one of bottlenecks that limits Apex
throughput when operators are deployed into different containers
including NODE_LOCAL case."
