I have migrated recently company clusters to 6.8.1 to use great features of x-pack, that not a long ago has been released to open source. I have two questions though:
- Can i use elasticsearch-certutil on one cluster to create 'ca' and p12 certificate bundles for using them on number of another elasticsearch clusters
- how much overhead ,in terms of performance, internode SSL encryption, and authentication before posting messages for indexing caused. I mean could it be a concern for cluster that handles tens of Terabytes of log events daily ?
