> Project: Ignite
> Issue Type: Task
> Affects Versions: 3.0.0-alpha2
> Reporter: Alexey Scherbakov
> Assignee: Alexey Scherbakov
> Priority: Major
> Labels: iep-61, ignite-3
> 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.
