[jira] [Created] (IGNITE-6717) Hashcode/equals is not needed for custom keys serialized into a binary form

Denis Magda created IGNITE-6717:
-----------------------------------

             Summary: Hashcode/equals is not needed for custom keys serialized into a binary form
                 Key: IGNITE-6717
                 URL: https://issues.apache.org/jira/browse/IGNITE-6717
             Project: Ignite
          Issue Type: Task
      Security Level: Public (Viewable by anyone)
            Reporter: Denis Magda
            Assignee: Denis Magda
             Fix For: 2.3


It turns out that hashCode/equals implementation is no longer required for custom complex keys if a key is serialized to the binary form. Discussed here:

The marshaller calculates the hash code automatically. This info has to be added to the binary marshaller page:
