Problem

Design how to sync relational databases across a faulty network connection.

Asked in the Final decomp (team lead) stage. Explain a practical design for reliable bidirectional synchronization, including change capture, retries, ordering, conflict resolution, consistency guarantees, and recovery after prolonged disconnection.

Clarify assumptions and synchronization semantics.
Design the client, transport, server, and storage workflow.
Handle duplicate delivery, reordering, partial writes, and schema changes.
Explain observability, testing, and operational failure recovery.

Keep the design implementable for relational data and explain where an ML component could help detect anomalous replication behavior without being part of the correctness path.
