Is sharding region of Apache IoTDB based on time sharding? How can I reduce the quantity of this region? I think there are too many of this, so I got this error reported, but if I set this quantity too small, the writing performance cannot keep up. The error message looks like this: [AsyncDataNodeloTConsensusServiceClientPool-selector-120] INFO o.a.i.c.i.c.AsyncIoTConsensusServiceClient: 113 - Unexpected exception occurs in AsyncConfigNodeIServiceClient{TEndPoint(ip:192.168.242.135, port:10760)}: java.lang.IllegalStateException: Client has an error. Anyone know how to deal with this?
You can adjust the number of region of Apache IoTDB through these two parameters: default_data_region_group_num_per_database and data_region_per_data_node. You can increase the rpc timeout (such as to half an hour) and then restart IoTDB. This problem will be alleviated. Or you can update your IoTDB version, since the new 1.3.0 version will no longer report this error.
