1. Federated Query Planning w/ Calcite & Substrait

• Speaker: Victor Barua (Datadog)
• Description: Substrait is a cross-language serialization format and specification for communicating relational plans across systems. It is currently under active development, and systems such as DataFusion and DuckDB have started to support consuming and producing Substrait plans. Another system that has support for Substrait is Calcite, via the Isthmus library.
  With Isthmus, it's possible to parse SQL queries with Calcite, perform planning and then delegate execution to external systems via Substrait plans. It's also possible to forgo SQL entirely, and submit Substrait plans directly to Calcite for planning. This talk aims to provide an introduction to Substrait, and showcase the capabilities of Isthmus in the context of generating plans for execution across multiple data systems.

2. Streaming, Incremental, Finite-Memory Computations in SQL Over Unbounded Streams
Speaker: Mihai Budiu (Feldera)

• Description: Learn how modern incremental view maintenance techniques make SQL the standard language for computing on unbounded streams. Mihai will showcase how indexes enable efficient updates with finite memory, solving challenges posed by growing unbounded data streams.

3. Revolutionizing Data Lakes SQL Interoperability and Optimization with Coral

• Speaker: Walaa Eldin Moustafa (LinkedIn)
• Description: TBA

4. Optimizing Common Table Expressions in Apache Hive with Calcite

• Speaker: Stamatis Zampetakis (Cloudera)
• Description: Discover how Apache Hive integrates with Apache Calcite to optimize common table expressions (CTEs). This talk explores techniques to detect, rewrite, and optimize CTEs, reducing query execution costs and improving efficiency.
