> Key: IGNITE-18091
> URL: https://issues.apache.org/jira/browse/IGNITE-18091
> Project: Ignite
> Issue Type: Task
> Reporter: Denis Chudov
> Assignee: Denis Chudov
> Priority: Major
> Labels: ignite-3
>
> *Motivation*
> Today we have several possible implementations of deadlock prevention: AI 3
> [1], transactions POC [2], and possible implementation based on concurrency
> control paper [3]. Moreover, we have a multiple granularity lock model [4]
> where some lock modes are compatible, others are not, which allows
> reenterability in some cases, and sharing of locks between transactions. We
> should understand the differences of behavior of each implementation in
> different scenarios, and how it matches with our expectations.
> *Definition of done*
> Table with a set of scenarios and description of behavior, including the
> expected one.
