Problem compressed vector tiles in MBTiles about go-pmtiles

[bdon]

can you share your MBTiles dataset, or at least the values in the metadata table?

[halset]

The metadata tables are equal. I am unfortunately not able to share the MBTiles. Should I add a compression row?

Bad one:

sqlite> select * from metadata where name != 'url_template';
name|naviz
format|pbf
minzoom|2
maxzoom|13

Good one:

sqlite> select * from metadata where name != 'url_template';
name|naviz
format|pbf
minzoom|2
maxzoom|13

Turns out, I had used zlib compression in the MBTiles, but I should have used gzip compression. Sorry for the noise.

@halset thanks for reporting back! The reason Gzip is supported instead of zlib, deflate, etc is to be readable directly in browsers. Is there a particular need addressed by using zlib? From what I understand Gzip is a header wrapper around a zlib payload.

No special reason. Just an error on my side in the code I wrote to create MBTiles. Fixed it now so my future MBTiles are gzip and work with go-pmtiles. Thank you.
