An Architecture for Fast and General Data Processing on Large Clusters https://bit.ly/440NCnR proposes an architecture for cluster computing systems that can tackle emerging data processing workloads at scale. Early cluster computing systems handled batch processing. Our architecture also enables streaming and interactive queries, while keeping scalability and fault tolerance.

A very beautiful talk on why distributed databases won't scale beyond a few 100s of TBs and how it's time for an architecture where storage isn't coupled with compute. ❗High operational overhead. ❗Log spikes. ❗Multi-tenancy. ❗Data reliability. ❗And always the high cost. Full talk here: https://lnkd.in/gtq9nA4Z

The Case for Shared Storage In this post, I’ll start off with a brief overview of “shared nothing” vs. “shared storage” architectures in general. This discussion will be a bit abstract and high-level, but the goal is to share with you some of the guiding philosophy that ultimately led to WarpStream’s architecture. We’ll then quickly transition to discussing the trade-offs between the two architectures more specifically in the context of data streaming and WarpStream; this is the WarpStream blog after all! https://lnkd.in/g9jBpQxD

Spark changed it’s memory architecture in 2016 to a “dynamic” unified memory architecture. Why? and what does “dynamic” mean? Spark’s unified memory is divided into 2 components, one for execution (where joins, aggregations happen) and the other for storage (where caching happens). Initially (< Spark 1.6), the portions for execution and storage memory were fixed. This meant that if your job is execution heavy and you’ve space left on the storage component (because there’s not a lot to cache), you still end up not using the storage memory and vice versa. This prompted to keep the slider between storage and execution memory movable (>= Spark 1.6) with more priority given to execution memory because at the end of the day, that is where your joins, aggregations etc.. happens. If execution needs memory, it evicts out RDD blocks from storage memory using the LRU algorithm. While on the other hand if storage needs more memory but it’s already being using by execution, storage will evict it’s own blocks based on LRU to make room for new data. Simple, yet beautiful. Have a look at the image below to understand various scenarios :) 👉Follow Girish Gowda for more data engineering related materials and information.

We managed to bring PyIceberg read times down from 50 seconds to 4 seconds by improving how we handle caching and network requests. It was a practical solution that made a noticeable difference in performance. If you're working with Iceberg and want to optimize data reads, you can find the details here 👇
