Data Channel Configuration

Internode communication uses the data channel to exchange table data during operations such as queries. The data channel is managed by the nodes in the cluster and implemented using normal TCP networking.

The data channel uses SSL to encrypt the data. The DataSSLParams configuration parameter is a string that must contain a comma-separated list of TLS credentials:

You must be a database administrator to set this parameter. You cannot set this parameter without setting the EncryptSpreadComm parameter. The EncryptSpreadComm parameter must be set as a completely separate step. It cannot be set at the same time as DataSSLParams in the same statement even if EncryptSpreadComm appears first in that statement. For more information, see Security Parameters.
