ODSC and Big Things Spain Conferences 2021, Dr. Frank Munz:
Abstract: "Data comes at us fast" is what they say. In fact, the last couple of years taught us how to successfully cleanse, store, retrieve, process, and visualize large amounts of data in a batch or streaming way. Despite these advances, data sharing has been severely limited because sharing solutions were tied to a single vendor, did not work for live data, came with severe security issues, and did not scale to the bandwidth of modern object stores.
Conferences have been filled for many years with sessions about how to architect applications and master the APIs of your services, but recent events have shown a huge business demand for sharing massive amounts of live data in the most direct scalable way possible. One example is open data sets of genomic data shared publicly for the development of vaccines. Still, many commercial use cases share news, financial or geological data to a restricted audience where the data has to be secured.
In this session, dive deep into an open-source solution for sharing massive amounts of live data in a cheap, secure, and scalable way. Delta sharing is an open-source project donated to the Linux Foundation. It uses an open REST protocol to secure the real-time exchange of large data sets, enabling secure data sharing across products for the first time.
It leverages modern cloud object stores, such as S3, ADLS, or GCS, to reliably transfer large data sets. There are two parties involved: Data Providers and Recipients. The data provider decides what data to share and runs a sharing server. An open-sourced reference sharing service is available to get started for sharing Apache Parque or Delta.io tables.
Any client supporting pandas, Apache Spark™, Rust, or Python, can connect to the sharing server. Clients always read the latest version of the data, and they can provide filters on the data (e.g., “country=ES”) to read a subset of the data.
