Writers Overview

GeoBrix ships a single raster writer, gdal, registered automatically whenever the GeoBrix JAR is on the classpath. Vector output flows through Spark's built-in writers or the product's native geospatial writers.

Available Writers

Writer	Format Name	Description
GDAL Writer	gdal	Emits each row's tile using the GDAL driver recorded in the tile's metadata.

At a Glance

• Input schema: exactly (source: string, tile: struct) — the reader's default schema. Don't .select() or add columns.
• Mode: .mode("append") only.
• Format on disk: comes from the driver stored in each tile's metadata. ext controls the filename suffix only.
• Target directory: must already exist; the writer does not create Volume roots.
