Heaptrack can handle millions of allocations per second, and thanks to the deduplication built into the trace file format combined with zstd compression, the overhead is pretty manageable. It's pretty hard to get "hundreds of GB" of data recorded.

Another thing: you can always just runtime attach and profile a partial time to reduce the amount of data recorded.

Finally: if your tools do so many allocations, maybe you should consider optimizing them...

Thanks! Should look into heaptrack - reading that it's linux only, but probably can be adopted for Windows?

MTuner exists for Windows which is similar but different. Porting heaptrack is not straight forward, as it heavily relies on libraries that do not work on Windows or do not support Windows executables and debugging information, such as libunwind and elfutils.
