Class StopRequestStore

java.lang.Object

com.knezevic.edaf.v3.persistence.jdbc.StopRequestStore

public final class StopRequestStore
extends Object

Persists/queries cooperative stop requests for long-running runs and experiments.

This store is intentionally defensive because stop checks run inside hot optimization loops. A transient persistence failure must never abort the optimization itself. Therefore:

• SQLite busy conditions are retried with bounded backoff.
• connection-pool exhaustion is treated as transient and handled fail-open for reads.
• acknowledgement writes are best effort during shutdown/finalization paths.
