---------------------------------------
Priority: Critical (was: Major)
> Lock LWM when executing an RO transaction on a data node
> --------------------------------------------------------
>
> Key: IGNITE-23748
> URL: https://issues.apache.org/jira/browse/IGNITE-23748
> Project: Ignite
> Issue Type: Improvement
> Reporter: Roman Puchkovskiy
> Priority: Critical
> Labels: ignite-3, important
>
> Global watermark mechanism proposed in IGNITE-23401 seems to be too complex,
> here a replacement is defined.
> # We need to lock local LWM not just on the coordinator (as it's done now),
> but on every data node that executes the RO transaction in question
> # If an attempt to lock local LWM with the RO transaction read timestamp
> fails, we need to return a failure instead of just ignoring the failure (it
> seems that now we just ignore it)
