Hi [~sdanilov]

could you please provide this change as patch on 2.9.1 ?

> Clarify WAL archive size configuration

>                 Key: IGNITE-12892
>                 URL: https://issues.apache.org/jira/browse/IGNITE-12892
>             Project: Ignite
>          Issue Type: Sub-task
>            Reporter: Semyon Danilov
>            Assignee: Semyon Danilov
>            Priority: Major
>             Fix For: 2.10

>          Time Spent: 1h 20m
>  Remaining Estimate: 0h

> Actual maximum size of WAL archive that can be reserved for historical 
> rebalance is calculated as minimum of three properties:
>  # DataStorageConfiguration#walHistSize (units: number of checkpoints)
>  # DataStorageConfiguration#maxWalArchiveSize (units: bytes)
>  # IgniteSystemProperties#IGNITE_PDS_MAX_CHECKPOINT_MEMORY_HISTORY_SIZE 
> (units: number of checkpoints)
> The logic is a little unclear, so I propose following changes:
>  # Stop using walHistSize at all (it's already deprecated) for WAL truncation
>  # Use IGNITE_PDS_MAX_CHECKPOINT_MEMORY_HISTORY_SIZE only in case WAL archive 
> is managed externally (so we limit the quantity of checkpoints stored in 
> memory, but don't remove WAL files)
>  # Use -1 for maxWalArchiveSize (instead of Long.MAX_VALUE) to disable WAL 
> truncation
