Hey all,
I have a general workflow which causes a memory leak. I have several functions which receive 1 or more rasters, perform some operations, and return a MemoryFile based raster, on which I perform other operations, which may also return a memory based raster, etc.
Closing this raster (or deleting the object) does not free the MemoryFile memory. So for now I have to propagate the memfile to all consumer functions which is annoying, not ergonomic, and prone to mistakes.
I'm familiar with rioxarray which might be useful, but we have a lot of code based on pure rasterio.
What is the best way to deal with this? Is it possible to create a specialized DatasetReader/DatasetWriter which closes the memory file on __del__?
Thanks
