- Delete this file and create more GitHub issues instead?
|
|
|
|
|
- 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?
|
|
|
|
|
- Implement basic support for aggregations over time (stats like min/max/avg)
|
|
|
|
|
- Optimization: Once a buffer is full, calculate min, max and avg
|
|
|
|
|
- Calculate averages buffer-wise, average weighted by length of buffer
|
|
|
|
|
- Implement basic support for query of most recent value for every metric on every host
|
|
|
|
|
- Optimize horizontal aggregations
|
|
|
|
|
- Optimize locking of levels in the tree structure
|
|
|
|
|
- In 99.9% of cases, no new level will need to be created, so all lookups into `level.children` will be read only
|
|
|
|
|
- `level.metrics` will be modified more often and will accesses will need to be serialized here
|
|
|
|
|
- Suggestion: Use a proper Mutex for `level.metrics`, but something read-optimized and possibly lock-free for `level.children`
|
