entity caching in hazelcast

[Hakan Küçük]

We currently utilize Hazelcast in a non-clustered environment alongside Spring Cache Abstraction. However, we now intend to transition into a clustered environment and require our cache to be replicated across multiple machines. The challenge we're facing is that our cached entities involve one-to-many relationships, resulting in slow performance.

For instance, consider the following example:

class Student { 

    int id; 

   String name;

   @OneToMany(lazy) List<Lecture> lectures; 

} 

 @Cacheable(name=Cache)

 List<Student> search(String namePrefix) { 

 }

During the serialization process, all lazy fields are being serialized. Since our entities have deep relationships and sometimes even circular references, this leads to a significant amount of data being transmitted over the network in the clustering setup.

Is there a configuration setting in Hazelcast that allows us to bypass the serialization of lazy fields?

You can implement a custom serializer and omit those fields: https://docs.hazelcast.com/hazelcast/5.3/serialization/compact-serialization#implementing-compactserializer
