Chipmink: Efficient Delta Identification for Massive Object Graph
Supawit Chockchowwat, Sumay Thakurdesai, Zhaoheng Li +2
Ranging from batch scripts to computational notebooks, modern data science tools rely on massive and evolving object graphs that represent structured data, models, plots, and more.…
Kishu: Time-Traveling for Computational Notebooks
Zhaoheng Li, Supawit Chockchowwat, Ribhav Sahu +2
Computational notebooks (e.g., Jupyter, Google Colab) are widely used by data scientists. A key feature of notebooks is the interactive computing model of iteratively executing cel…
AirIndex: Versatile Index Tuning Through Data and Storage
Supawit Chockchowwat, Wenjie Liu, Yongjoo Park
The end-to-end lookup latency of a hierarchical index -- such as a B-tree or a learned index -- is determined by its structure such as the number of layers, the kinds of branching…
Transactional Python for Durable Machine Learning: Vision, Challenges, and Feasibility
Supawit Chockchowwat, Zhaoheng Li, Yongjoo Park
In machine learning (ML), Python serves as a convenient abstraction for working with key libraries such as PyTorch, scikit-learn, and others. Unlike DBMS, however, Python applicati…
A Step Toward Deep Online Aggregation (Extended Version)
Nikhil Sheoran, Supawit Chockchowwat, Arav Chheda +3
For exploratory data analysis, it is often desirable to know what answers you are likely to get before actually obtaining those answers. This can potentially be achieved by designi…
Automatically Finding Optimal Index Structure
Supawit Chockchowwat, Wenjie Liu, Yongjoo Park
Existing learned indexes (e.g., RMI, ALEX, PGM) optimize the internal regressor of each node, not the overall structure such as index height, the size of each layer, etc. In this p…
Airphant: Cloud-oriented Document Indexing
Supawit Chockchowwat, Chaitanya Sood, Yongjoo Park
Modern data warehouses can scale compute nodes independently of storage. These systems persist their data on cloud storage, which is always available and cost-efficient. Ad-hoc com…
