There is an implementation for Spark 3, but GraphFrames isn't released
often enough to match every point version. It supports Spark 3.4. Try it -
it will probably work.

I think it is awesome. Brilliant interface that is missing from Spark.
Would you integrate with something like MLFlow?

Usually, the solution to these problems is to do less per line, break it
out and perform each minute operation as a field, then combine those into a
final answer. Can you do that here?

Oops, it has been long since Russell labored on Hadoop, speculative
execution isn’t the right term - that is something else. Cascading has a
declarative interface so you can plan more, whereas Spark is more
imperative. Point remains :)

I don't think Spark can do this with its current architecture. It has to
wait for the step to be done, speculative execution isn't possible. Others
probably know more about why that is.

I had to create a pyspark.sql.Row in a map operation in an RDD before I
call spark.createDataFrame. Check out lines 92-138.
Not sure if this helps, but I thought I'd give it a try ;)

What is the actual deployment model for Spark Streaming? All I know to do
right now is to restart the PID. I'm new to Spark, and the docs don't
really explain this (that I can see).

Actually, I can imagine a one or two line fix for this bug: call
row.asDict() inside a wrapper for DataFrame.rdd. Probably deluding myself
this could be so easily resolved? :)

to a database is a pretty common thing to do from PySpark, and lots
of analysis must be happening in DataFrames in PySpark?
Anyway, the workaround for this bug is easy, cast the rows as dicts:
my_dataframe = my_dataframe.map(lambda row: row.asDict())

Ok, I'm also unable to save to Elasticsearch using a dataframe's RDD. This
seems related to DataFrames. Is there a way to convert a DataFrame's RDD to
a 'normal' RDD?

To answer my own question, DataFrame.toJSON() does this, so there is no
need to map and json.dump():
on_time_dataframe.toJSON().saveAsTextFile('../data/On_Time_On_Time_Performance_2015.jsonl')
Thanks!
