Compute and Storage Separation

[thompson0012]

i have read the introduction of PolarDB (Compute Storage Seperation for PostgreSQL)

what i think is: can i use juicedata as the storage layer? (instead of the filesystem)
which means, i store the db file from postgres in object storage , so that can achieve the same architecture?

postgres -> db file (file system)
postgres -> db file (juicedata, backed by object storage)

[thompson0012]

if it works, it would be solve the problem from scale-out? right?

i would like to hear the why and why not

It is true that some people use juicefs as a storage tier for databases, and we recommend actually testing the performance.
