Do you find yourself struggling with Pandas' limitations when handling massive datasets or real-time data streams?

Discover Polars, the lightning-fast DataFrame library built in Rust. This talk presents two advanced features of the next-generation dataframe library: lazy queries and streaming mode.

Lazy evaluation in Polars allows you to build complex data pipelines without the performance bottlenecks of eager execution. By deferring computation, Polars optimises your queries using techniques like predicate and projection pushdown, reducing unnecessary computations and memory overhead. This leads to significant performance improvements, particularly with datasets larger than your system’s physical memory.

Polars' LazyFrames form the foundation of the library’s streaming mode, enabling efficient streaming pipelines, real-time transformations, and seamless integration with various data sinks.

This session will explore use cases and technical implementations of both lazy queries and streaming mode. We’ll also include live-coding demonstrations to introduce the tool, showcase best practices, and highlight common pitfalls.

Attendees will walk away with practical knowledge of lazy queries and streaming mode, ready to apply these tools in their daily work as data engineers or data scientists.

Change data feeds are a common tool for synchronizing changes between tables and performing data processing in a scalable fashion. Serverless architectures offer a compelling solution for organizations looking to avoid the complexity of managing infrastructure. But how can you bring CDFs into a serverless environment? In this session, we'll explore how to integrate Change Data Feeds into serverless architectures using Delta-rs and Delta-kernel-rs—open-source projects that allow you to read Delta tables and their change data feeds in Rust or Python. We’ll demonstrate how to use these tools with Lakestore’s serverless platform to easily stream and process changes. You’ll learn how to: Leverage Delta tables and CDFs in serverless environments Utilize Databricks and Unity Catalog without needing Apache Spark

Join us as we introduce Delta-Kernel-RS, a new Rust implementation of the Delta Lake protocol designed for unparalleled interoperability across query engines. In this session, we will explore how maintaining a native implementation of the Delta specification — with native C and C++ FFI support — can deliver consistent benefits across diverse data processing systems, eliminating the need for repetitive, engine-specific reimplementations. We will dive deep into a real-world case study where a query engine harnessed Delta-Kernel-RS to unlock significant data skipping improvements — enhancements achieved “for free” by leveraging the kernel. Attendees will gain insights into the architectural decisions, interoperability strategies and the practical impact of this innovation on performance and development efficiency in modern data ecosystems.

Delta Kernel makes it easy for engines and connectors to read and write Delta tables. It supports many Delta features and robust connectors, including DuckDB, Clickhouse, Spice AI and delta-dotnet. In this session, we'll cover lessons learned about how to build a high-performance library that lets engines integrate the way they want, while not having to worry about the details of the Delta protocol. We'll talk through how we streamlined the API as well as its changes and underlying motivations. We'll discuss some new highlight features like write support, and the ability to do CDF scans. Finally we'll cover the future roadmap for the Kernel project and what you can expect from the project over the coming year.

Five years ago, the delta-rs project embarked on a journey to bring Delta Lake's robust capabilities to the Rust & Python ecosystem. In this talk, we'll delve into the triumphs, tribulations and lessons learned along the way. We'll explore how delta-rs has matured alongside the thriving Rust data ecosystem, adapting to its evolving landscape and overcoming the challenges of maintaining a complex data project. Join us as we share insights into the project's evolution, the symbiotic relationship between delta-rs and the Rust community, and the current hurdles and future directions that lie ahead.

Spark applications often need to query external data sources such as file-based data sources or relational data sources. In order to do this, Spark provides Data Source APIs to access structured data through Spark SQL.

Data Source APIs have optimization rules such as filter push down and column pruning to reduce the amount of data that needs to be processed to improve query performance. As part of our ongoing project to provide generic Data Source V2 push down APIs, we have introduced partial aggregate push down, which significantly speeds up spark jobs by dramatically reducing the amount of data transferred between data sources and Spark. We have implemented aggregate push down in both JDBC and parquet.

Scribd's data architecture was originally batch-oriented, but in the last couple years, we introduced streaming data ingestion to provide near-real-time ad hoc query capability, mitigate the need for more batch processing tasks, and set the foundation for building real-time data applications.

Kafka and Delta Lake are the two key components of our streaming ingestion pipeline. Various applications and services write messages to Kafka as events are happening. We were tasked with getting these messages into Delta Lake quickly and efficiently.

Our first solution was to deploy Spark Structured Streaming jobs. This got us off the ground quickly, but had some downsides.

Since Delta Lake and the Delta transaction protocol are open source, we kicked off a project to implement our own Rust ingestion daemon. We were confident we could deliver a Rust implementation since our ingestion jobs are append only. Rust offers high performance with a focus on code safety and modern syntax.

In this talk I will describe Scribd's unique approach to ingesting messages from Kafka topics into Delta Lake tables. I will describe the architecture, deployment model, and performance of our solution, which leverages the kafka-delta-ingest Rust daemon and the delta-rs crate hosted in auto-scaling ECS services. I will discuss foundational design aspects for achieving data integrity such as distributed locking with DynamoDb to overcome S3's lack of "PutIfAbsent" semantics, and avoiding duplicates or data loss when multiple concurrent tasks are handling the same stream. I'll highlight the reliability and performance characteristics we've observed so far. I'll also describe the Terraform deployment model we use to deliver our 70-and-growing production ingestion streams into AWS.

Rust guarantees zero memory access bug once a program compiles. However, one can still introduce logical bugs in the implementation.

In this talk, I will first give a high level overview on common formal verification methods used in distributed system designs and implementations. Then I will talk about our experiences with using TLA+ and Stateright to formally model delta-rs' multi-writer S3 backend implementation. The end result of combining both Rust and formal verification is we end up with an efficient native Delta Lake implementation that is both memory safe and logical bug free!
