Resolved! Feature store : Can create_training_set() be implemented to execute an inner join?

For timeseries feature tables, an inner join is made at the creation of the feature table. For the other type of feature tables, a left join is made, so NaN values can show up in the training set. Can the inner join in create_training_set() method be...

Thank you Hubert, that's a good alternative, I just thought I'd stick to the api as much as possible, but this solves it.

Can you deploy models that can be queried/called/inferred outside your organization?

It looks like you can via MLflow but I wanted to check before diving deeper?Also it seems like if it is possible, it's just for small scale experimentation?Thank you!

Yes, If somebody outside Databricks can query/use a model built in Databricks. I assume the answer must be yes?

What can I do to reduce the number of MLflow API calls I make?

I'm fitting multiple models in parallel. For each one, I'm logging lots of params and metrics to MLflow. I'm hitting rate limits, causing problems in my jobs.

The first thing to try is to log in batches. If you are logging each param and metric separately, you're making 1 API call per param and 1 per metric. Instead, you should use the batch logging APIs; e.g. use "log_params" instead of "log_param" http...

Yes, you will hit rate limits if you try to query the API so fast in parallel. Do you just want to manipulate the run data in an experiment with Spark? you can simply load all that data in a DataFrame with spark.read.format("mlflow-experiment").load(...

For tuning hyperparameters with Apache Spark ML / MLlib, when should I use Spark ML's built-in tuning algorithms vs. Hyperopt?

When should I use Spark ML's CrossValidator or TrainValidationSplit, vs. a separate tuning tool such as Hyperopt?

Both are valid choices. By default, I'd recommend using Hyperopt nowadays. Here's the rationale, as pros & cons of each.Spark ML's built-in toolsPros: These fit the Spark ML Pipeline framework, so you can keep using the same type of APIs.Cons: Thes...

In this case, you just want your feature store to have a timestamp column as a timestamp key. You would compute your features as of whatever dates you like and add them as features, and those are used to train. At runtime, to make a prediction as of ...
