B-tree
Keep keys ordered in a balanced tree for lookups and range scans.
Use this when Queries filter by equality, compare ranges, or request indexed ordering.
without the term
“Choose an ordered index for these equality and range queries and verify that it helps.”
with the term · How do you ask a model for B-tree?
Evaluate a B-tree index for these equality and range queries. Verify the plans and write overhead.
What is B-tree?
A B-tree stores ordered keys in balanced levels. Database implementations often use B+ tree variants; PostgreSQL’s B-tree indexes support equality and ordered comparisons.
Why does B-tree matter when vibe coding?
An agent can choose an index by name while its expressions or column order do not fit the query.
How do you do B-tree?
Match the operator and key order to real queries. Inspect plans for equality, range, and ordering cases and measure write cost.
What goes wrong with B-tree?
An index can be slower than a scan for a large result set; existence does not guarantee selection.

B-tree supports equality and ordered range comparisons; suitability depends on the operator and query.
