## Summary of changes This PR introduces three new abstractions: 1. `Resolver`: Resolves which reader and writer to use for a template. 2. `Writer`: Writes a template project to disk. Prompts the user if necessary. 3. `Reader`: Reads a template specification from disk, built into the CLI or from GitHub. Introducing these abstractions helps decouple reading a template from writing it. When I tried adding telemetry for the `bundle init` command, I noticed that the code in `cmd/init.go` was getting convoluted and hard to test. A future change could have accidentally logged PII when a user initialised a custom template. Hedging against that risk is important here because we use a generic untyped `map<string, string>` representation in the backend to log telemetry for the `databricks bundle init`. Otherwise, we risk accidentally breaking our compliance with our centralization requirements. ### Details After this PR there are two classes of templates that can be initialized: 1. A `databricks` template: This could be a builtin template or a template outside the CLI like mlops-stacks, which is still owned and managed by Databricks. These templates log their telemetry arguments and template name. 2. A `custom` template: These are templates created by and managed by the end user. In these templates we do not log the template name and args. Instead a generic placeholder string of "custom" is logged in our telemetry system. NOTE: The functionality of the `databricks bundle init` command remains the same after this PR. Only the internal abstractions used are changed. ## Tests New unit tests. Existing golden and unit tests. Also a fair bit of manual testing. |
