Missing Testcases:
- Port at least all blackbox tests from the "old" MemoryStore to the new implementation
- Check for corner cases that should fail gracefully
- Write a more realistic ToArchive/FromArchive tests
- Test edgecases for horizontal aggregations
Release Data
- Implement API endpoint for releasing old data
- Make sure data is written to disk before it is released
- Automatically free up old buffers periodically?
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
Implement basic support for query of most recent value for every metric on every host
Optimize horizontal aggregations
All metrics are known in advance, including the level: Use this to replace level.metrics hashmap by slice?
