SAIS EU 2019 Sessions) **[Delta Lake Blog](https://daily.dev/sources/delta-lake)** · 6 min read · 0 upvotes · 0 comments ## Summary A community newsletter roundup covering Delta Lake happenings from early October 2019, including the release of Delta Lake 0.4.0 with new Python APIs, links to recent blog posts on schema enforcement, brand safety, and genome-wide association studies use cases, past and upcoming webinars, a long list of Delta Lake sessions at Spark+AI Summit EU 2019 in Amsterdam, and a rundown of meetups held and planned across cities worldwide. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### What new feature did Delta Lake 0.4.0 introduce? Delta Lake 0.4.0 introduced Python APIs, enabling developers to perform upserts and deletes on Delta Lake tables directly using Python rather than relying solely on Scala or SQL. This made it easier to get started with reliable, ACID-compliant table operations in Delta Lake from Python-based data pipelines. _Developers evaluating Delta Lake's Python support can track library updates like this on daily.dev._ ## Similar posts on daily.dev - [DuckDB Ecosystem Newsletter : June 2026](https://daily.dev/posts/duckdb-ecosystem-newsletter-june-2026-nnbadzzs6) · MotherDuck · 1 upvotes · 0 comments - [Delta Lake Explained: Boost Data Reliability in Cloud Storage](https://daily.dev/posts/delta-lake-explained-boost-data-reliability-in-cloud-storage-oechbmvm4) · databricks · 0 upvotes · 0 comments - [DuckDB Ecosystem Newsletter : July 2026](https://daily.dev/posts/duckdb-ecosystem-newsletter-july-2026-vbq5wdyas) · MotherDuck · 1 upvotes · 0 comments - [Building for the AI Era: Lakebase, Streaming, and Lakehouse Innovations at VLDB 2026](https://daily.dev/posts/building-for-the-ai-era-lakebase-streaming-and-lakehouse-innovations-at-vldb-2026-tho7yyzku) · databricks · 3 upvotes · 0 comments - [DuckDB Ecosystem Newsletter – March 2026](https://daily.dev/posts/duckdb-ecosystem-newsletter-march-2026-d8usjokdm) · MotherDuck · 0 upvotes · 0 comments --- Tags: [#data-engineering](https://daily.dev/tags/data-engineering), [#apache-spark](https://daily.dev/tags/apache-spark), [#databricks](https://daily.dev/tags/databricks) [View this post on daily.dev](https://daily.dev/posts/delta-lake-newsletter-2019-10-03-edition-incl-sais-eu-2019-sessions--hytipeifl) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@type":"TechArticle","headline":"Delta Lake Newsletter: 2019-10-03 Edition (incl.
