------------------------------------
Summary: Integrate communication with coordinator in tx protocol
Key: IGNITE-5932
URL: https://issues.apache.org/jira/browse/IGNITE-5932
Project: Ignite
Issue Type: Sub-task
Components: cache
Reporter: Semen Boikov
Assignee: Semen Boikov
Need integrate communication with coordinator in transactions protocol:
- after locks are acquired need request ID from coordinator
- this ID should be passed to primary/backups and passed to update
- after tx is committed need notify coordinator
Notes:
- there are differences in prepare logic for
optimistic/pessimistic/serializable transactions, so most probably work with
coordinator should be implemented separately for these tx types
- need support case when coordinator fails during prepare (need think is
necessary rollback and retry tx or switch to next assigned coordinator)
