This is interesting. We recently deployed a solution that uses pmtiles and it's great.

https://docs.protomaps.com/pmtiles/

afaik, pmtiles uses mvt, let's hope the tooling to convert the tiles to mlt also becomes available.

PMTiles is actually pretty agnostic to what kind of tiles it contains! There is already a PMTiles PR that updates the byte that specifies the type of tile to include MLT.

Oh wow, thank you, looking forward to this

Neat, as someone integrating PMTiles right now, thank you!

PMtiles is often used with MVT tiles, but it can encapsulate a variety of tile types: the current spec [1] has defined tile types for MVT, PNG, JPEG, WebP and AVIF (plus "Unknown/Other").

Absolutely, we have MVT tiles at the moment, I'm hoping to test MLT soon

I'm building PMTiles through Tilemaker, PMTiles is incredible, but sadly it will take a lot of work to produce MLT though Tilemaker :/

Oh pmtiles is such a simple and innovative solution!

Yes, Absolutely in love with it. Loading tiles with range requests made our application so much faster.

It's very cool! If you want to get higher cache hit rates from a CDN or redis etc. and lower the amount of S3 reads, you can get set up a proxy to convert `/{z}/{x}/{y}.mvt` requests into the byte-range requests: https://docs.protomaps.com/deploy/

Brandon has some example code you can lift to dump it into a Cloudflare Worker or other platforms on that page.

Thank you. I'm going to try this on a different project that we have. Our current deployment is designed to work directly through s3/api gateway which reduces the number of moving parts.

We update the tiles frequently, so the setup has been amazing for us.

It is. I’ve found it so useful I created an Elixir library to act as a cache in front on a pmtiles file. https://hex.pm/packages/ex_pmtiles
