> Exclude deprecated fields from node-to-node transmission after RU is completed
> ------------------------------------------------------------------------------
>
> Key: IGNITE-29120
> URL: https://issues.apache.org/jira/browse/IGNITE-29120
> Project: Ignite
> Issue Type: Task
> Reporter: Mikhail Petrov
> Assignee: Mikhail Petrov
> Priority: Major
> Time Spent: 50m
> Remaining Estimate: 0h
>
> Consider two schemas for the same message, each corresponding to a different
> Ignite version.
> {code:java}
> 2.19 2.20
> A A
> B B (deprecated)
> C C
> {code}
> While RU is in progress, field B is still filled by the previous logical
> version's code, so it must be transmitted:
> RU in progress (logical version is 2.19)
> {code:java}
> 2.20 <------------> 2.20
> A A A
> B (filled) B B (filled)
> C C C
> {code}
> Once RU is finished, the new logical version no longer fills B, so it is
> always null and we don't want to send it anymore. But the nodes have already
> agreed on B, so it is still transmitted:
> RU finished (logical version is 2.20)
> {code:java}
> 2.20 <------------> 2.20
> A A A
> B (null) B B (null)
> C C C
> {code}
> We need to support excluding deprecated field from transmission.
