Does it support custom tile scheme?

[King-JXN]

I have a scene like this: Given a tile scheme, including resolution and scale, how does it create vector tile with target level in the tile scheme

No With Table Source and Yes With Function Source

Not Support With Table Source

The answer would be not If you are using the Table Source . As martin fetch tiles with this:

martin/martin/src/pg/query_tables.rs

Lines 187 to 210 in 59040a8

	let query = format!(
	r#"
	SELECT
	ST_AsMVT(tile, {layer_id}, {extent}, 'geom'{id_name})
	FROM (
	SELECT
	ST_AsMVTGeom(
	ST_Transform(ST_CurveToLine({geometry_column}), 3857),
	ST_TileEnvelope($1::integer, $2::integer, $3::integer),
	{extent}, {buffer}, {clip_geom}
	) AS geom
	{id_field}{properties}
	FROM
	{schema}.{table}
	WHERE
	{geometry_column} && ST_Transform({bbox_search}, {srid})
	{limit_clause}
	) AS tile;
	"#
	)
	.trim()
	.to_string();
	Ok((id, PgSqlInfo::new(query, false, info.format_id()), info))

See more on the postgis doc.

• ST_AsMVTGeom

Yes With Function Source

But with Function Source you could make tile envelop with your custom tile schema. So the answer would be yes.
