I've just pushed in libtiff upstream, and its internal copy in GDAL, support
zstd compression , and the appropriate changes in the GDAL GeoTIFF driver.
This requires building libtiff (or GDAL with its internal libtiff copy) against
libzstd >= 1.0
My findings are that single-core compression is at least twice faster with zstd
deflate, for equivalent or better compression rate. Decompression is a bit
faster, but not
So a compelling use case for zstd is potentially in complex processing chains
have many intermediate internal products. At that point of adoption, I'd not
for consumer-facing products.
