does anyone know any concern if I construct a cluster with data nodes with different disk size?
5 data nodes with 200GB Disk
5 data nodes with 1TB disk and
5 data nodes with 10TB disk.
Will this cause any issue if the data size fill up those small nodes?
Elasticsearch assumes all nodes have the same amount of disk so that would cause a problem unless you divide your cluster into "zones" using shard allocation filtering, e.g. hot/warm/cold architecture.
