I am still going through the documentation for ES, since we are at 1.x and would like to upgrade.
I couldnt port the data from one instance to new instance due to different hop versions to go with breaking changes.
We will require to run only in single node even in production, since we retain the data only one node and then data retention is set for only a week.
The reason for choosing one node :
We use timeseries database to store the data as the end result of our pipeline.
Do you think we can still setup to discovery type to single in production or we need to put some other special configs to ensure its the only master node for ES?
