[Future Data] Storage Metadata for Modern Cloud Databases

Speaker:

Joyo Victor

System:

SingleStore

In modern database architecture, separating compute from storage unlocks powerful capabilities. Our tiered storage, “bottomless”, started by uploading files to remote object storage. This worked well until we wanted to create database branches pointing to the same remote storage. One branch does not know if it can delete a file that another branch depends on. To solve this, we built... Read More

[Fall 2025] Astronomer / Apache AirFlow Tech Talk

Speaker:

Julian LaNeve

System:

AirFlow

Apache Airflow is the most popular data orchestration tool there is, downloaded over 40m times per month and used to power the data, ML, and AI platforms at OpenAI, Lyft, Airbnb, Uber, and Apple. At its core, Airflow allows you to define data workflows as DAGs using Python. We’ll do a deep dive on how Airflow came to be and... Read More

[Future Data] Where We’re Going, We Don’t Need Rows: Columnar Data Connectivity with ADBC

Speaker:

Ian Cook

ADBC (Arrow Database Connectivity) is Apache Arrow’s answer to ODBC and JDBC: It’s a database access API and driver standard that delivers data in Arrow columnar format instead of a row-oriented format. ADBC is on a roll, speeding and simplifying data access for dbt, Databricks, DuckDB, Microsoft, Snowflake, and more. This talk presents the architecture of ADBC (APIs, drivers, driver... Read More

[Future Data] Vortex: LLVM for File Formats

Apache Parquet revolutionized columnar storage after its initial release in 2013, but has largely failed to evolve since then. As a result, nearly every Tier 1 tech company has built their own columnar format to replace Parquet. Enter Vortex, a Linux Foundation project that currently achieves 100x faster random access, 10-20x faster scans, and 5x higher write throughput, while maintaining... Read More

[Future Data] DuckLake: Learning from Cloud Data Warehouses to Build a Robust “Lakehouse”

Speaker:

Jordan Tigani

System:

When building scalable data systems, it is easy to focus on the storage and the compute, but metadata a critical third piece that is often overlooked. This talk will describe how metadata storage enables query performance and helps provide transactional semantics in modern data warehouses. We will then go into how the metadata story in popular open data formats take... Read More

[Future Data] Apache Hudi: A Database Layer over Cloud Storage for Fast Mutations and Efficient Queries

Speaker:

Vinoth Chandar

System:

Hudi

Video:

YouTube

Data lakes emerged as a way to store vast amounts of data as files and objects on infinitely scalable cloud storage, with processing done on scalable distributed compute engines. However, this architecture lacks many of the capabilities of traditional databases, such as efficient mutations, indexing, and transaction management. Apache Hudi was created as the first "lakehouse" project, to bridge this... Read More

[Fall 2025] On Holistic Database Optimization via Leveraging Similarity Across Actions, Workloads, Configurations, and Scenarios (William Zhang)

Speaker:

William Zhang

Modern database management systems (DBMSs) have evolved to support increasingly sophisticated data-intensive applications, at the cost of substantial complexity to configure them for two reasons. First, DBMSs expose a vast configuration space with trillions of possibilities that encompass system knobs, physical design (e.g., indexes), and query options, amongst others. Second, these applications are constantly evolving with changes in data access... Read More

What are you trying to tell me? That I can read data fast? No, User. I'm trying to tell you that when you are ready, you won't have to. Everyone's heard about how fast Apache Iceberg and maybe you've even heard a few notes about "predicate pushdown" and "file metrics" but you've been left wanting more. You want to know... Read More
