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?
Thanks,

Then there could be some opportunities that one SG belongs to many regions (for
adding regions for existed SG). If so, I think the following design may be more
formal. What do you think?
ALTER STORAGE GROUP ADD (DATA | SCHEMA) REGION
And I think we should also display the region count in SHOW
Hi,
We will create a region for this storage group, and allocate all replicas
of this region to datanodes. Then, newly created data partition could be
routed to this region.
1. Does the exist data under the prefixPath will be automatically migrated
to the new region?
Currently, no.
But we

Hi,
Could you explain what will happen after a region being created manually in
detail? And I have some questions about this SQL
1. Does the exist data under the prefixPath will be automatically migrated to
the new region?
2. Does the prefixPath must be a storage group name, or any arbitrary
Hi,
I'm planning to add a SQL for IoTDB cluster version. Here are the
details of this SQL:
Motivation:We don't have enough evidence to design an
optimalRegionGroupexpansion algorithm yet.
If a large number of devices are created in a StorageGroup and the
SeriesPartitionSlot is filled, the

Is back to normal.
