Re: Read a big geotiff，it went memory overflow error

[Jia Yu]

Hi,

Each GeoTiff image is treated as a single record in Sedona DataFrame. It
means that the image itself is not partitioned and cannot be too large. The
use scenario of Sedona is that you have tons of small GeoTiff images rather
than a single big image.

Thanks,
Jia
