Analyze key distribution across multiple nodes in a Redis Cluster (6.0.x)

[Jeff Schafer]

Hi -- I'm looking for thoughts (best practice) on how to do key distribution analysis on a Redis cluster.  All of my keys have a prefix, separator, and ID and I need to gather stats on prefix counts, ID variations, and possibly on some of the values within each hash.

Ultimately I guess I'm looking at warehousing style analysis.

Size of overall cluster is around 300M keys.

Using open source version.

Ideas or descriptions of successful solutions are all welcome.

Thanks -- Jeff
