Difference between partitioning (vertical split) and sharding (horizontal split across servers)

Three partitioning strategies: range, list, and hash partitioning with real use cases

How partition pruning makes queries 10-100x faster by skipping irrelevant partitions

Sharding strategies and how Instagram, Discord, and Uber distribute data across servers

When to partition (single server, 100M+ rows) vs when to shard (multiple servers, billions of rows)

Partition maintenance: adding, dropping, and archiving old partitions

Sharding challenges: cross-shard queries, rebalancing, and maintaining consistency

Real-world decision framework for choosing partition keys and shard keys
