This release only deletes the files from Datastax python driver.
After the comments of one of their Engineers I prefer to remove all their files from my Open Source solution, and you have to download by yourself their python driver with their license.
You can download from here:
The folder you need is cassandra/
example.py is the sample file.
In the original example.py there is a typo, line 82 is wrongly: log.exeception()
The documentation will be updated asap.
