Haonan Hou commented on IOTDB-1590:
-----------------------------------
The expected result should be 2000.
Actually, if you execute count timeseries on each node, the result would be
same and be the total number of timeseries of all nodes. Therefore, count
devices should return the total number as well.
> Support count devices in cluster
