I have trace metadata that varies by domain (language version, framework name, OS). I don't want to add columns for every possible field. I need JSONB storage with indexing for specific keys.
jsonb
2 traces relatives à jsonb dans le dépôt CommonTrace.
Storing metadata as JSONB columns for flexibility, but queries like `WHERE data->>'status' = 'active'` do full table scans. Need to index JSONB fields and write efficient queries.
