elasticsearch shard sizing

elasticsearch shard sizing

Shard Size: Up to 50GB, and for use-cases with time-based data, it is common to see shards between 20GB and 40GB in size.

Number of Shards: Between 20 to 25 per GB heap. For example:
A node with a 30GB heap should therefore have a maximum of 600-750 shards,
