Size of the tile buffer on each side. A value of 0 produces no buffer. A value of 512 produces a buffer as wide as the tile itself. Larger values produce fewer rendering artifacts near tile edges and slower performance.

If the data is a collection of point features, setting this to true clusters the points by radius into groups. Cluster groups become new Point features in the source with additional properties:

Max zoom on which to cluster points if clustering is enabled. Defaults to one zoom less than maxzoom (so that last zoom features are not clustered). Clusters are re-evaluated at integer zoom levels so setting clusterMaxZoom to 14 means the clusters will be displayed until z15.

Radius of each cluster if clustering is enabled. A value of 512 indicates a radius equal to the width of a tile.

Whether to generate ids for the geojson features. When enabled, the feature.id property will be auto assigned based on its index in the features array, over-writing any previous values.

Whether to calculate line distance metrics. This is required for line layers that specify line-gradient values.

Maximum zoom level at which to create vector tiles (higher means greater detail at high zoom levels).

When loading a map, if PrefetchZoomDelta is set to any number greater than 0, the map will first request a tile at zoom level lower than zoom - delta, but so that the zoom level is multiple of delta, in an attempt to display a full map at lower resolution as quick as possible. It will get clamped at the tile source minimum zoom. The default delta is 4.

Douglas-Peucker simplification tolerance (higher means simpler geometries and faster performance).
