Vespa Schema Authoring
Vespa .sd schemas — fields, tensors/HNSW, rank profiles
Vespa · Apache-2.0
When
Writing, validating and evolving Vespa .sd schema files: field types, indexing pipelines, match modes, tensors and HNSW, rank profiles, structs, fieldsets, common pitfalls.
The Catch
Apache-2.0 from the repo LICENSE; SKILL.md declares none. Engine is Apache-2.0 and free to self-host forever; Vespa Cloud is a free trial only ($300 credits, no card, app stops when credits run out) — not forever-$0 Cloud. Vespa-specific .sd grammar — not Elasticsearch mappings. Schema changes can require reindexing; verify with deploy validation.
