Hi, I am confused about why our current algorithm cannot expand RegionGroup automatically and had to add region manually by DBA? Is it possible to set a threshold when SeriesPartitionSlot is coming filled and execute the logic you create a region automatically?

Here are the details of this SQL: Motivation: We don't have enough evidence to design an optimal RegionGroup expansion algorithm yet. If a large number of devices are created in a StorageGroup and the SeriesPartitionSlot is filled, the current algorithm cannot expand RegionGroup anymore. Therefore, we need a special SQL to enable DBA expand RegionGroup manually. Syntax Definition: create (data | schema) region on prefixPath(Represent a specific StorageGroup) Function Definition: Create a new data/schema RegionGroup for the specific StorageGroup. ------------------------------------------------------------------------------------------------------------ Yongzao Dan, School of Software, Tsinghua University
