Partition downsampling #15

Open bluestreak01 opened 3 years ago

bluestreak01 commented 3 years ago

Summary

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.
