[ML] Explain data frame analytics API by dimitris-athanasiou · Pull Request #49455 · elastic/elasticsearch

dimitris-athanasiou · 2019-11-21T17:44:39Z

This commit replaces the _estimate_memory_usage API with
a new API, the _explain API.

The API consolidates information that is useful before
creating a data frame analytics job.

It includes:

memory estimation
field selection explanation

Memory estimation is moved here from what was previously
calculated in the _estimate_memory_usage API.

Field selection is a new feature that explains to the user
whether each available field was selected to be included or
not in the analysis. In the case it was not included, it also
explains the reason why.

I'll come back to add this

I have now added this in

@alvarezmelissa87 pinging you as this is the PR that adds field selection explanation

dimitris-athanasiou · 2019-11-21T17:46:21Z

@szabosteve I'm updating documentation too in this PR, could you please take a look at the docs changes?

Great stuff! Some minor comments.

Also, I think you might need to black list the failure focused yaml tests for the ml with security tests

Thank you @dimitris-athanasiou for documenting this! I left a couple of minor comments, but it LGTM.

Should these be kept in sync with log-levels in AnalyticsProcessManager.java (which are currently info)?

As this API is not part of the life-cycle of the job, I'd rather it stays quiet in the info level unless something goes wrong.

Objects.requireNonNull?
Also, should we use ExceptionHelper.requireNonNull instead?

ExceptionsHelper.requireNonNull makes sense for user facing code. We thus use it when we parse request objects. In this case we create this ourselves Objects.requireNonNull should be enough.
