Nikita Amelchev updated IGNITE-29286:
-------------------------------------
Description:
Transaction and get messages still carry fields and flags that no node reads
anymore. They are filled in and sent with every transaction and remote get, so
they should be deprecated and excluded from the wire once a rolling upgrade
completes.
A client and two server nodes in one JVM, TRANSACTIONAL cache, `backups=1`,
`FULL_SYNC`; bytes sent by `TcpCommunicationSpi` of all nodes per operation,
with the deprecation features active (as after a finalized rolling upgrade):
| Operation | Before | After |
|---|---|---|
| PESSIMISTIC transaction putting two keys with different primaries | 2460 B |
2416 B (−44 B, −1.8%) |
| Near cache `getAll` of two keys with different primaries | 486 B | 434 B (−52
B, −10.7%) |
