Data Systems Lab

The Data Systems Lab focuses on how storage systems behave under real application constraints.

Core Topics

• relational modeling
• indexes and query behavior
• transactions
• isolation levels
• write contention
• replication lag
• leader-follower patterns
• sharding
• eventual consistency
• search indexing

Why This Lab Matters

Many developers know database terms without seeing how those choices affect correctness and latency in a running system.

Desired Output

Users should be able to explain:

• what consistency model a flow needs
• what stale reads can break
• where transaction boundaries matter
• when data duplication is acceptable
