[FLI-847] Proposal: Copy Namespace API

[markphelps]

Problem

If namespaces are used as environments its challenging to copy data from one namespace to another without relying on export/import.

Ideal Solution

It would be nice if we provided a 'Copy Namespace API' that allows the user to duplicate all data from one namespace to a new or potentially existing one. More on the latter below.

Potential Structure

URL: POST /api/v1/namespaces/{sourceNamespace}/copy
Body:

{
  "target": {
    "key": "string",
   },
  "conflict_strategy": "fail"
}

Field Descriptions

• target/target.key contains info about the destination namespace either to be created or existing. its an object to allow for future iteration (ie: maybe we add a name field allowing the new namespace to be created with key and name, by default name will match key)
• conflict_strategy: options fail | overwrite , specifies what to do on conflict (only for existing namespaces) that is conflicts that occur from object key/id collision. Either we fail the operation or overwrite the target namespace. Default would be fail.

Etc

• After this API existed we could then easily add the ability to copy namespaces in the UI
• This would only work for relational backends as declarative backends are read-only

Search

• I searched for other open and closed issues before opening this
