Now I need link repositories in JetBrains Space (for others Git system) to Datalore, have any plan for this feature?
Could you please describe your use case in more details? What do you mean by saying link repositories in JetBrains Space (for others Git system) to Datalore? What do you expect?
You can use Space repository as any other private repository. Just create an application password for this. You can even use Space API in a notebook if you add token to secrets. Here is the demo I done for JPoint in spring: JetBrains Datalore: A powerful environment for Jupyter notebooks.
