@triump2020 Yes, it has been used in various use cases in many servers as a storage engine.

@greensky00 thanks for your quick response !
BTW, in ebay, has there been any case in where jungle has been used as a wal-raft-log store ? we want to multiplex it,
namely to improve the performance for the disk io , we plan to put multi wal-logs come from different raft groups into one
Jungle instance which correspond to one disk. is it feasible ? how did it performs? Thanks again !

@triump2020
Yes, one of the use cases of Jungle is the Raft log store, but we use one Jungle instance for each Raft group (there can be multiple isolated instances in a single process). If you want to share multiple log stores on a single Jungle instance, you may need to have a mapping from each log store's index number to Jungle's sequence number. That won't be easy while the benefit is questionable compared to having multiple Jungle instances.

@greensky00 Got it , thanks!
