The significance of Delta Lake 2.0 is not just a number - though it is timed quite nicely with Delta Lake’s 3rd birthday. It reiterates our collective commitment to the open-sourcing of Delta Lake, as announced by Michael Armbrust’s Day 1 keynote at Data + AI Summit 2022.Tue, 02 Aug 2022 00:00:00 GMThttps://delta.io/blog/2022-05-18-multi-cluster-writes-to-delta-lake-storage-in-s3/https://delta.io/blog/2022-05-18-multi-cluster-writes-to-delta-lake-storage-in-s3/While Delta Lake has supported concurrent reads from multiple clusters since its inception, there were limitations for multi-cluster writes specifically to Amazon S3. Note, this was not a limitation for Azure ADLSgen2 nor Google GCS, as S3 currently lacks “put-If-Absent” consistency guarantees. Thus, to guarantee ACID transactions on S3, one would need to have concurrent writes originating from the same Apache Spark™ driver. This was one of the most requested issues by the community and we are excited to announce that Delta Lake 1.2 (release notes, blog) now supports writing data from multiple clusters to S3 while maintaining the transactionality of the writes.Wed, 18 May 2022 00:00:00 GMThttps://delta.io/blog/2022-05-05-delta-lake-1-2-released/https://delta.io/blog/2022-05-05-delta-lake-1-2-released/Introducing performance optimizations that will supercharge your data pipelines at any scale.Thu, 05 May 2022 00:00:00 GMThttps://delta.io/blog/2022-04-27-writing-to-delta-lake-from-apache-flink/https://delta.io/blog/2022-04-27-writing-to-delta-lake-from-apache-flink/Learn more about how you can write from Apache Flink to Delta Lake about the latest release of the open-source project Delta Sharing and how it enables sharing on Google Cloud Storage, among other enhancements.Wed, 27 Apr 2022 00:00:00 GMThttps://delta.io/blog/2022-03-11-delta-sharing-0-4-0-released/https://delta.io/blog/2022-03-11-delta-sharing-0-4-0-released/Learn more about the latest release of the open-source project Delta Sharing and how it enables sharing on Google Cloud Storage, among other enhancements.Fri, 11 Mar 2022 00:00:00 GMThttps://delta.io/blog/2022-01-06-delta-connectors-0-3-0-released/https://delta.io/blog/2022-01-06-delta-connectors-0-3-0-released/We are excited to announce the release of Delta Connectors 0.3.0.Thu, 06 Jan 2022 00:00:00 GMThttps://delta.io/blog/2021-12-03-delta-release-1-1-0-released/https://delta.io/blog/2021-12-03-delta-release-1-1-0-released/We are excited to announce the release of Delta Lake 1.1.0.Fri, 03 Dec 2021 00:00:00 GMThttps://delta.io/blog/2021-12-01-delta-sharing-0-3-0-released/https://delta.io/blog/2021-12-01-delta-sharing-0-3-0-released/We are excited to announce the release of Delta Sharing 0.3.0.Wed, 01 Dec 2021 00:00:00 GMThttps://delta.io/blog/2021-11-16-power-bi-delta-sharing-connector/https://delta.io/blog/2021-11-16-power-bi-delta-sharing-connector/We are excited about the recently announced preview of the Power BI Delta Sharing connectorTue, 16 Nov 2021 00:00:00 GMThttps://delta.io/blog/2021-09-16-delta-lake-survey-2021-h2/https://delta.io/blog/2021-09-16-delta-lake-survey-2021-h2/We would like to invite you to provide your feedback on Delta Lake OSS.Thu, 16 Sep 2021 00:00:00 GMThttps://delta.io/blog/2021-05-24-delta-lake-1-0-0-released/https://delta.io/blog/2021-05-24-delta-lake-1-0-0-released/We are excited to announce the release of Delta Lake 1.0.0 on Apache Spark 3.1.Mon, 24 May 2021 00:00:00 GMThttps://delta.io/blog/2021-03-02-ama-growing-the-delta-lake-ecosystem/https://delta.io/blog/2021-03-02-ama-growing-the-delta-lake-ecosystem/On March 11th, 2021 9:00 am PT, join us for this fun Delta Lake AMA session where we discuss with QP Hou, Christian Williams, and Alexander Kushnir from Scribd on growing the Delta Lake open-source ecosystem.Tue, 02 Mar 2021 00:00:00 GMThttps://delta.io/blog/2021-03-02-salesforce-engineering-delta-lake-tech-talk-series/https://delta.io/blog/2021-03-02-salesforce-engineering-delta-lake-tech-talk-series/We are happy to announce the Salesforce Engineering Delta Lake Tech Talk Series for March and April 2021.Tue, 02 Mar 2021 00:00:00 GMThttps://delta.io/blog/2021-02-04-delta-lake-0-8-0-released/https://delta.io/blog/2021-02-04-delta-lake-0-8-0-released/We are excited to announce the release of Delta Lake 0.8.0.Thu, 04 Feb 2021 00:00:00 GMThttps://delta.io/blog/2020-10-20-salesforce-engineering-delta-lake-blog-series/https://delta.io/blog/2020-10-20-salesforce-engineering-delta-lake-blog-series/Salesforce Engineering has published a series of blogs on how they use Delta Lake.Tue, 20 Oct 2020 00:00:00 GMThttps://delta.io/blog/2020-10-14-salesforce-engineering-global-synchronousness-and-ordering-in-delta-lake/https://delta.io/blog/2020-10-14-salesforce-engineering-global-synchronousness-and-ordering-in-delta-lake/At Salesforce, we maintain a platform to capture customer activity — various kinds of sales events such as emails, meetings, and videos.
