Answer
Keep transactions small, align operations with shard keys, avoid multi-collection writes, and reduce batch size to prevent distributed rollback overhead.
Quick Answer
To avoid large distributed transactions: design schemas so related data lives on the same shard (same shard key prefix), use event sourcing or saga patterns for multi-shard workflows instead of transactions, break large operations into smaller single-shard transactions with compensating logic, and use the transactional outbox pattern to coordinate across service boundaries without cross-shard transactions.
