Indexing Strategy and Design Questions
Choosing and designing indexes: B-tree, hash, composite, covering, partial, and full-text/inverted indexes, and the trade-offs between read acceleration and write/storage overhead. Covers selecting index columns from query patterns, cardinality and selectivity reasoning, diagnosing why an index is or is not used, and index maintenance: rebuilding or reorganizing a fragmented index, finding and dropping redundant or unused indexes, and rolling out a new index to production safely. Also covers indexing in analytical (bitmap, columnar), partitioned, and distributed/NoSQL systems. Central to database performance interviews.
