– TransactionBulkService uses Spring Data JPA’s saveAll() wrapped in a single transaction. When the number of valid rows exceeds the configured batch size (default = 5 000), the service splits the list into sub‑batches to avoid hitting the JDBC parameter limit.
Overall code quality is high and matches the team’s standards. FSDSS-536
