> This is a follow-up to HDDS-8485.
> The issue of delayed delete block processing in SCM still persists due to 
> internal behavior in Apache Ratis.
> Although a timer-based flush mechanism was introduced, its effectiveness is 
> limited because Ratis enforces a *minimum transaction gap (1024)* before 
> triggering certain operations such as snapshot-related checks.
> *Code Reference: [RaftServerImpl (lines 
> 1317–1320)|https://github.com/apache/ratis/blob/f141e10551a1bef69c0c7387dd184bc88e821b6d/ratis-server/src/main/java/org/apache/ratis/server/impl/RaftServerImpl.java#L1317-L1320]*
> Because of this constraint, flush operations remain indirectly gated by the 
> transaction gap, negating the intended benefit of the timer-based approach.
> *Proposed Fix*
>  * Reduce the value of {{ozone.scm.ha.ratis.server.snapshot.creation.gap}} 
> from *1024 to 1*
>  * Remove this configuration from Ozone to avoid duplication and rely on 
> appropriate defaults within Ratis
