Method	`POST`
Operation	`UpdateTraceField`
Auth	`Authorization: Bearer $HANZO_API_KEY`

Changes how one span field is stored — selects or deselects it as a materialized column and tunes its index — and echoes the setting back.

Callers need the editor role; the runtime's own gate enforces it.

Request

6 fields, body application/json (required).

Field	In	Type	Required	Description
`dataType`	body	string	yes	DataType is the field's data type, e.g.
`index`	body	string	—	Index is the index expression to put on the column, e.g.
`indexGranularity`	body	integer	—	IndexGranularity is the index granularity in rows.
`name`	body	string	yes	Name is the field to tune.
`selected`	body	boolean	—	Selected materializes the field as its own column when true.
`type`	body	string	yes	Type is where the field lives: attributes or resources.

Response

Status	Body	Meaning
`200`	o11y.O11yFieldSetting	ok
