Queries getting sluggish? Index strategy matters.

In Webdock’s Beginner’s Guide: Clustered vs Non-clustered Index, you'll find a clean breakdown of how these two index types impact performance:

  • Clustered Index - orders data physically by the indexed column. Ideal for range queries, but only one allowed per table.
  • Non-clustered Index - lives in a separate B-tree structure with pointers to the data. Multiple per table, great for specific lookups.

Key reminders:

  • Clustered is table-level sorting; best for ranges (e.g., id, timestamps).
  • Non-clustered assists lookups on filtered fields (e.g., username, email), at some write cost.

Understanding when and how to use each can turn slow queries into efficient hits.
