Indexes aren’t magic —
…but they often look like magic when your query goes 40 sec → 20 ms. ⚡

🏆 5 Index Types Everyone Should Know

• 🔹 Clustered Index — defines table order

• 🔹 Nonclustered Index — fast lookup

• 🔹 Include Columns — covering index booster

• 🔹 Filtered Index — tiny but powerful

• 🔹 Columnstore Index — analytics monster

-- Example: filtered index
CREATE INDEX IX_Orders_Active
ON Orders(Status)
WHERE Status = 'Active';

💡 Bonus

Never add indexes “everywhere”. Measure impact with Query Store.
