The motivation here is to replace old partition content with lower resolution data by means of running a down-sampling logic, such as 1-minute average or similar. This would reduce disk space occupied by partition data while keeping summaries.
Expected outcome
There will be a dedicated SQL syntax to down-sample either individual or range of partitions. The operation will be transactional. It would also be integrated with #14 when it is ready.
