Spark Basics | Partitions
Ғылым және технология
Spark is a distributed computing system that is used within Foundry to run data transformations at scale. This series covers the core Spark concepts you need to know for working with data in Foundry.
In this video we introduce partitions, discuss the importance of partition sizing, demonstrate how to find the count and size of partitions for a dataset in Foundry, and describe methods for changing the number of partitions in a Spark DataFrame.

Please keep this series going. Your spark tutorials are very useful. ! Making me love your product more and more
Hi Team, Found this video really informative, I'll be really grateful if you guys can put some more data partitioning concepts and methods along with some advance best practices while working with spark. I'm new to Spark, I wanna learn it very thoroughly. Thanks
This video gave me ideas about my recurrent OOM driver problems, cause : many too small partitions
Great video! More hadoop videos please)
can we get into detail on the methods on repartition?
need more videos
I had a requirement of having space in partition.But when I am writing data to S3 in parquet format with space in partition, it is failing Can I please have a solution?
Use delta lake 2.0 and the optimize command and never worry about the headache of managing partition size or counts again.
The video quality is quite good, but I'd appreciate if the videos are more beginner friendly. 😀
