> Key: IGNITE-23401
> URL: https://issues.apache.org/jira/browse/IGNITE-23401
> Project: Ignite
> Issue Type: Bug
> Reporter: Pavel Tupitsyn
> Priority: Critical
> Labels: ignite-3, important
> Fix For: 3.0
>
>
> Read-only transaction locks Low Watermark at the given timestamp on the
> coordinator, so that relevant data is not removed by GC while the transaction
> is active.
> However, other nodes have independent Low Watermark instances, which can move
> past the read timestamp and cause the data to be removed.
> To solve this, we should introduce a Global Low Watermark and lock it for RO
> transactions.
> Reproducer: https://github.com/apache/ignite-3/pull/4533
