[gdal-dev] GDAL memory management

[Jesús]

Hi,

I have been working with C/C++ and GDAL with GEOS for some time now and I
have a question about GDAL memory management.

I wonder if there are any memory management options or tips to control
allocations and deallocations in the library since we are noticing
performance problems as our data increases in complexity, mainly OGR
operations (intersection, simplify).

For example, I would expect something to do the same as:
- std::allocator: http://www.cplusplus.com/reference/memory/allocator/
- CGAL allocator:
https://doc.cgal.org/latest/Manual/devman_memory_management.html
- SQLite memory allocation routines:
https://www.sqlite.org/c3ref/mem_methods.html

I have been looking for it, but GDAL is so big that maybe I missed
something.

Thanks,

Jesus Cano
