I have 9 tenants. Each tenant is about 1 TB. Could I create 1 index for each tenant? so 9 indices in total? this would mean each index is 1 TB 9 TB of data over 9 indices. To maintain safe shard size, my index will have 48 Primaries (so each shard is 25 GB). Does this design look good? ---

That seems reasonable. It might be worth trying different shard sizes as from 30-50 gig is the usual recommendation, and you might find a different size is better for your use case. ---

The ideal shard size will depend on your data as well as your queries and latency requirements. 25GB sounds like a good starting point but i would recommend running a benchmark with realistic data and queries. The result could be larger or smaller than 25GB. The 30GB to 50GB is often recommended for time-series data queried through aggregations. If your use case is a search use case your optimum may however be quite different. ---
