Andrew, what would be the purpose of thread-safe access: just making it thread-safe without any particular requirement on how efficient this would be (1), or hope for true concurrent access with ideally close to linear scalability with the number of threads (2) ? If (1), then we could add a

If the purpose of multithreading is performance, a mutex will ruin that performance. Opening different datasets solves that already. For writing, allowing different synchronous writers is... scary. On Mon, 3 Jun 2024, 16:12 Chris Toney via gdal-dev, < gdal-dev@lists.osgeo.org> wrote: > Hi

[gdal-dev] Thread-safe raster access

2024-06-03 Thread Andrew Bell via gdal-dev
Hi, I am aware that there isn't thread-safe raster access with the current GDAL interface for various reasons. Given the state of processors, I was wondering if it would be valuable to take a look at providing the ability to do Raster I/O (at least reads) in a thread-safe way. This could be done
