In an ideal world, every data source you want to connect to already has a Spark data source implementation (either v1 or v2), then this Python API is useless. But I feel it's common that people want to do quick data exploration, and the target data system is not popular enough to have an existing Spark data source implementation. It will be useful if people can quickly implement a Spark data source using their favorite Python language.I'm +1 to this proposal, assuming that we will keep it simple and won't copy all the complicated features we built in DS v2 to this new Python API.On Tue, Jun 20, 2023 at 2:11 PM Maciej <mszymkiew...@gmail.com> wrote: Similarly to Jacek, I feel it fails to document an actual community need for such a feature. Currently, any data source implementation has the potential to benefit Spark users across all supported and third-party clients. For generally available sources, this is advantageous for the whole Spark community and avoids creating 1st and 2nd-tier citizens. This is even more important with new officially supported languages being added through connect. Instead, we might rather document in detail the process of implementing a new source using current APIs and work towards easily extensible or customizable sources, in case there is such a need.-- Best regards,Maciej Szymkiewicz Web:https://zero323.net PGP: A30CEF0C31A501EC On 6/20/23 05:19, Hyukjin Kwon wrote:Actually I support this idea in a way that Python developers don't have to learn Scala to write their own source (and separate packaging). This is more crucial especially when you want to write a simple data source that interacts with the Python ecosystem.

Were there any? I'm just curious. I've seen no emails requesting it. I also doubt that Python devs would like to work on new data sources but support their wishes wholeheartedly :) Pozdrawiam, Jacek Laskowski ---- "The Internals Of" Online Books <https://books.japila.pl/> Follow me on https://twitter.com/jaceklaskowski <https://twitter.com/jaceklaskowski> On Fri, Jun 16, 2023 at 6:14 AM Allison Wang <allison.w...@databricks.com.invalid> <mailto:allison.w...@databricks.com.invalid> wrote: Hi everyone, I would like to start a discussion on “Python Data Source API”. This proposal aims to introduce a simple API in Python for Data Sources. The idea is to enable Python developers to create data sources without having to learn Scala or deal with the complexities of the current data source APIs. The goal is to make a Python-based API that is simple and easy to use, thus making Spark more accessible to the wider Python developer community. This proposed approach is based on the recently introduced Python user-defined table functions with extensions to support data sources. *SPIP Doc*: https://docs.google.com/document/d/1oYrCKEKHzznljYfJO4kx5K_Npcgt1Slyfph3NEk7JRU/edit?usp=sharing *SPIP JIRA*: https://issues.apache.org/jira/browse/SPARK-44076 Looking forward to your feedback.
