Master node resource requirement

It is understood that Master node resource specification is lesser that the of the data nodes. Wanted to know how many cpu cores, Memory and Disc space a typical Master node can have, considering 3 dedicated master eligible nodes in an elasticsearch cluster.

Dedicated master nodes need persistent storage, but not a lot of it. 1-2 CPU cores and 2-4GB RAM is often sufficient for smaller deployments. As dedicated master nodes do not store data you can also set the heap to a higher percentage (75%-80%) of total RAM that is recommended for data nodes.

We have around 4,5TB data with hot and warm node architecture and coordinating nodes.
