Erica Fischer 7130d21bf5 Merge remote-tracking branch 'origin/main' into clean-polygons 2023-12-22 14:38:02 -08:00
Erica Fischer 02e3bac2c0 Reduce memory consumption during tiling (#177) 
* Drop duplicate geometries sooner in coalescing-as-needed

* Concatenate geometries before partial cleaning

* Spend less time with two feature representations in memory

* Further reduce in-memory duplication

* Remove another copy

* Don't keep duplicates in memory while coalescing

* Also clear out the mvt layer once it is no longer needed

* Update changelog

Erica Fischer d359461e61 Reduce tile-join overzooming memory usage (#162) 
* 16 bits is enough for tile numbers

* Revert "16 bits is enough for tile numbers"

This reverts commit 71a0c4e1cf.

* Check what child tiles each overzoomed tile will have

and don't queue further overzooming of empty tiles

* Clean up naming; use std::move to avoid copying large arrays
