> Key: IGNITE-10663
> URL: https://issues.apache.org/jira/browse/IGNITE-10663
> Project: Ignite
> Issue Type: Task
> Reporter: Anton Vinogradov
> Assignee: Anton Vinogradov
> Priority: Major
> Labels: iep-31
> Fix For: 2.8
>
>
> The main idea is to provide special "read from cache" mode which will read a
> value from primary and all backups and will check that values are the same.
> In case values differ they should be fixed according to the appropriate
> strategy.
> ToDo list:
> 1) {{cache.withConsistency().get(key)}} should guarantee values will be
> checked across the topology and fixed if necessary.
> 2) LWW (Last Write Wins) strategy should be used for validation.
> 3) Since LWW and any other strategy do not guarantee that the correct value
> will be chosen.
> We have to record the event contains all values and the chosen one.
