Improve checkpoints/archives
- Store information in each buffer if already archived
- Do not create new checkpoint if all buffers already archived
Missing Testcases:
- General tests
- Check for corner cases that should fail gracefully
- Write a more realistic ToArchive/FromArchive tests
Optimization: Once a buffer is full, calculate min, max and avg
- Calculate averages buffer-wise, average weighted by length of buffer
- Only the head-buffer needs to be fully traversed
Optimization: If aggregating over hwthreads/cores/sockets cache those results and reuse some of that for new queres aggregating only over the newer data
