A Spark Application can consist of more than one session A SparkSession on the other hand is associated to a Spark Application: Generally, a session is an interaction between two or more entities. With the help of tremendous contributions from the open-source community, this release resolved more than 3400 tickets as the result of contributions from over 440 contributors.A Spark job can consist of more than just a single map and reduce. Apache Spark 3.0 builds on many of the innovations from Spark 2.x, bringing new ideas as well as continuing long-term projects that have been in development. This release is based on git tag v3.0.0 which includes all commits up to June 10.

We have curated a list of high level changes here, grouped by major modules. You can consult JIRA for the detailed changes. This release improves its functionalities and usability, including the pandas UDF API redesign with Python type hints, new pandas UDF types, and more Pythonic error handling.Here are the feature highlights in Spark 3.0: adaptive query execution dynamic partition pruning ANSI SQL compliance significant improvements in pandas APIs new UI for structured streaming up to 40x speedups for calling R user-defined functions accelerator-aware scheduler and SQL reference documentation.To download Apache Spark 3.0.0, visit the downloads page. PySpark has more than 5 million monthly downloads on PyPI, the Python Package Index. In TPC-DS 30TB benchmark, Spark 3.0 is roughly two times faster than Spark 2.4.Python is now the most widely used language on Spark.
