Hello,
Could anybody prompt me, please? Is it possible to remove one node from the cluster with replication factor 1 without lost data? What is the best solution to do it? Aspike - isn’t the enterprise version.
Thanks in advance.

Enterprise has quiesce which allows you to move a node out of the replica list which would allow removing a node from a replication factor 1 cluster without data loss.
Community doesn’t have this feature, so you will need to maintain more than one replica if you want to perform these actions without data loss.
You could run asbackup -l <nodeip:port> -n <namespace> -o <filename>
on that host to take a backup… then after you take it down, restore that data to the cluster. You’d potentially lose any updates made while the backup was ongoing, and lose reads/update while the data was unavailable. Depending on the nature of your data, that’s your call to make.
