Description

Hi guys, we are also using PebbleDB, the data scale is 19.5B KV number, and the storage occupies 1.4TB.

I would like to ask a question, for pebbledb or similar LSM-tree DB, what size of storage can be efficiently read and written? Do you have any experience? At what scale is sharding better than a single database?
