------------------------------------------
Summary: Implement LockManager with deadlock prevention based on
operation ordering
Key: IGNITE-15057
URL: https://issues.apache.org/jira/browse/IGNITE-15057
Project: Ignite
Issue Type: Task
Affects Versions: 3.0.0-alpha2
Reporter: Alexey Scherbakov
Assignee: Alexey Scherbakov
Fix For: 3.0.0-alpha3
We assume two phase locking concurrency control in the first version of tx
protocol in Ignite 3.
We need a LockManager implementing this functionality.
If a shared/exclusive lock is acquired in incompatible mode, only "newest"
operations are allowed to wait for "oldest", according to ordering based on
globally comparable timestamp.
Otherwise, newer transactions are restarted preserving it's timestamp.
