* `mbtiles diff` now has an additional `--patch-type` param with `whole`, `bin-diff-raw` and `bin-diff-gz` values: * `whole` stores different tiles as before - as whole tiles in the `tiles` table * `bin-diff-raw` computes binary difference between tiles, and stores them as brotli-encoded value in a `bsdiffraw` table, together with a `xxh3_64` hash of the tile as it will be stored after patching * `bin-diff-gz` same as `bin-diff-raw`, but assumes the tiles are gzip-compressed, so it uncompresses them before comparing. The `xxh3_64` stores the hash of the uncompressed tile. The data will be stored in the `bsdiffrawgz` table (identical structure with above) * `mbtiles copy --apply-patch` will automatically detect if `bsdiffrawgz` or `bsdiffraw` tables exist, and will use binary patching. * `mbtiles apply-patch` does not support binary patching yet * `mbtiles copy --diff-with-file ... --patch-type ...` is an alias to `mbtiles diff --patch-type ...` |
