Right-sizing Spark executor memory
At LinkedIn, we rely heavily on offline analytics for making data-driven decisions. Apache Spark provides a significant amount of the compute infrastructure powering use cases like data warehousing, data science, AI/ML, A/B testing, and metrics reporting. The scale of Spark at LinkedIn is significant with 150k+ unique jobs responsible for 300k+ executions consuming 200 petabyte-hours of compute da
Comparing Apache Flink and Spark for Modern Stream Data Processing
The ability to harness and act upon data in real time has become a critical differentiator, enabling everything from personalized customer experiences to optimized supply chain management. Traditional batch-oriented approaches to ETL (Extract, Transform, Load) and its variants, ELT and Reverse ETL, struggle to keep up, highlighting their limitations and the need for more agile and scalable solutio

Apache Spark Shuffle Service — there are more than one options!!
The purpose of this blog is to provide a list of Shuffle Service Implementations in Apache Spark and motivation for their design choices. This blog will also cover the high level understanding of Spark Shuffle service. Credit Note: All Credit goes to actual blogs and you tube videos published already for each Shuffle service implementation and the relevant links have been added in each section of
Spark Architecture
Edit from 2015/12/17: Memory model described in this article is deprecated starting Apache Spark 1.6+, the new memory model is based on UnifiedMemoryManager and described in this article Over the recent time I’ve answered a series of questions related to ApacheSpark architecture on StackOverflow. All of them seem to be caused by the absence of a good general description of the Spark architecture i
Spark Architecture: Shuffle
This is my second article about Apache Spark architecture and today I will be more specific and tell you about the shuffle, one of the most interesting topics in the overall Spark design. The previous part was mostly about general Spark architecture and its memory management. It can be accessed here. The next one is about Spark memory management and it is available here. What is the shuffle in gen

Project Nessie, Apache Iceberg, and Apache Spark Using Docker
In today’s modern data lakes, you work with a separation of data and metadata with open table formats like Apache Iceberg giving you vastly improved query performance, the ability to time-travel, evolve your table’s partitions/schema, and much more. Open table formats rely on metadata catalogs to track where the metadata lives so engines can access the tables using these formats. Tools like AWS Gl
