---------------------------------------
Summary: Improve locks scalability (was: Optimize coarse-grained locks)
> Improve locks scalability
> -------------------------
>
> Key: IGNITE-23301
> URL: https://issues.apache.org/jira/browse/IGNITE-23301
> Project: Ignite
> Issue Type: Improvement
> Affects Versions: 3.0.0-beta1
> Reporter: Alexey Scherbakov
> Assignee: Alexey Scherbakov
> Priority: Major
> Labels: ignite-3
> Fix For: 3.0
>
>
> Currently coarse-grained (table,index) locks use the same path as
> fine-grained key locks.
> This leads to broken TPS scaling in high amount of cores environments due to
> high contention.
> This can be fixed by implementing specialized type of locks to handle high
> contention scenarios.
> We need only IX and S locks to enforce serializability in the current
> approach.
> IX locks can be implemented as counter-based and we need only tryLock(IX)
