Mahendershah commented 6 years ago

Hello ,

I am facing one issue when my Layer is having Multiple Styles in place, there is multiple database query that is getting fired. I have tried using true on the layer, but still this not helping me. When I have Layer with 2 styles there is 2 execute of query that is getting fired. Any help on this? I am using Mapnik 3.0.9 version.

Thanks Mahender Shah

Hi, you can set cache-features="true" on the Layer to prevent database query per each style. You have to keep in mind that it consumes some memory depending on how many and how big those features are. This is why the option is set to false by default.
