Hi Reynold,

Sure, new function from_csv() has the same signature as from_json().

The options are passed to the function via map, for example:
select from_csv('2
We could also deprecate Py2 already in the 2.4.0 release.

It's not splitting hairs, Erik. It's actually very close to something that
I think deserves some discussion (perhaps on a separate thread.) What I've
been thinking about also concerns API "friendliness" or style. The original
RDD API was very intentionally modeled on the Scala parallel collections
I write code to connect kafka with spark using python and I run code on

My 2 cents on this is that the biggest room for improvement in Python is
similarity to Pandas. We already made the Python DataFrame API different from
Scala/Java in some respects, but if there’s anything we can do to make it more
obvious to Pandas users, that will help the most. The other issue
Most of those are pretty difficult to add though, because they are
fundamentally difficult to do in a distributed setting and with lazy
execution.
We should add some but at some point there are fundamental differences
between the underlying execution engine that are pretty difficult to
reconcile.

That's a big chunk of what I'm getting at: How much is it even possible to
do this kind of reconciliation from the underlying implementation to a more
normal/expected/friendly API for a given programming environment? How much
more work is it for us to maintain multiple
I don’t think we should remove any API even in a major release without
deprecating it first...

Subject: Re: Should python-2 be supported in Spark 3.0?
I am not involved with the design or development of the V2 API - so these could
be naïve comments/thoughts.
Just as dataset is to abstract away from RDD, which otherwise required a little
more intimate knowledge about Spark internals, I am guessing the absence of
partition operations is either d
I'm +1 for this proposal: "Extend SessionConfigSupport to support passing
specific white-listed configuration values"
One goal of data source v2 API is to not depend on any high-level APIs like
SparkSession, SQLConf, etc. If users do want to access these high-level
APIs, there is a workaround: cal
I think we can deprecate it in 3.x.0 and remove it in Spark 4.0.0. Many
people still use Python 2. Also, techincally 2.7 support is not officially
dropped yet - https://pythonclock.org/

+1 for this idea since text parsing in CSV/JSON is quite common.
One thing is about schema inference likewise with JSON functionality. In
case of JSON, we added schema_of_json for it and same thing should be able
to apply to CSV too.
If we see some more needs for it, we can consider a function lik

A few preliminary notes:
Wenchen for some weird reason when I hit your key in gpg --import, it
asks for a passphrase. When I skip it, it's fine, gpg can still verify
the signature. No issue there really.
The staging repo gives a 404:

Ah I missed the Scala 2.12 build. Do you mean we should publish a Scala
2.12 build this time? Current for Scala 2.11 we have 3 builds: with hadoop
2.7, with hadoop 2.6, without hadoop. Shall we do the same thing for Scala
2.12?

I think one build is enough, but haven't thought it through. The
Hadoop 2.6/2.7 builds are already nearly redundant. 2.12 is probably
best advertised as a 'beta'. So maybe publish a no-hadoop build of it?
Really, whatever's the easy thing to do.
