At the moment we’re excited to announce that Delta Sharing is mostly accessible (GA) on AWS and Azure. With the GA launch, you may anticipate the very best stage of stability, assist, and enterprise readiness from Databricks for mission-critical workloads on the Databricks Lakehouse Platform. On this weblog, we discover how organizations leverage Delta Sharing to maximise the enterprise worth of their knowledge, among the key options accessible within the GA launch, and the best way to get began with Delta Sharing on the Databricks Lakehouse Platform.
Prospects win with the open normal for knowledge sharing from the lakehouse
Knowledge sharing has turn into vital within the digital economic system as enterprises look to simply and securely alternate knowledge with their prospects, companions, suppliers, and inner traces of enterprise (LOBs) to raised collaborate and unlock worth from that knowledge. However the lack of a standards-based knowledge sharing protocol has resulted in options tied to a single vendor or business product, introducing vendor lock-in dangers. These buyer challenges led us, at Databricks, to construct an open knowledge sharing resolution, Delta Sharing. Delta Sharing gives an open resolution to securely share dwell knowledge out of your lakehouse to any computing platform. Knowledge recipients do not must be on the Databricks Lakehouse Platform or on the identical cloud or on any cloud in any respect. Knowledge suppliers can share current large-scale knowledge units primarily based on the Apache Parquet or Delta Lake codecs, with out replicating or copying knowledge units to a different system. Knowledge recipients profit from all the time gaining access to the newest model of knowledge with the flexibility to question, visualize, rework, ingest or enrich shared knowledge with their instruments of selection, decreasing time-to-value. As governance and safety are high considerations for a lot of organizations, Delta Sharing is natively built-in with Unity Catalog, permitting you to handle, govern, audit, and monitor utilization of the shared knowledge on one platform.

What’s new in Delta Sharing with GA?
Whereas Delta Sharing has a slate of fantastic options within the GA launch, offered beneath are among the key options we’re transport with this launch:
Seamless Databricks to Databricks Sharing
For Databrick prospects, Delta Sharing makes knowledge sharing on the lakehouse very simple, environment friendly and safe. With only a few UI clicks or SQL instructions, knowledge suppliers can simply share their current knowledge with recipients on Databricks, with out replicating the information. For instance, an information supplier utilizing Databricks on AWS can share current knowledge with a recipient utilizing Databricks on Azure or vice-versa. You’ll be able to discover the person information for full particulars. In Databricks to Databricks sharing, the information supplier doesn’t have to handle token credentials for recipients who’re utilizing Databricks; the sharing connection is established securely by way of the Databricks platform. All you want is a Databricks account to login and the remaining is taken care of by the platform. Along with cross-account knowledge sharing, one other vital use case is inner knowledge sharing. When you’ve got a number of Unity Catalog metastores below the identical account in numerous areas, you may simply share knowledge amongst these metastores by utilizing Delta Sharing with out copying any knowledge. SQL workflow instance from an information supplier’s perspective:
-- create a share and add a desk to it
CREATE SHARE first_share;
ALTER SHARE first_share ADD TABLE my_table AS default.first_table;
-- create a Databricks recipient utilizing their sharing identifier and grant them entry to the share
CREATE RECIPIENT acme USING ID 'aws:us-west-2:3f9b6bf4-...-29bb621ec110';
GRANT SELECT ON SHARE first_share TO RECIPIENT acme;
SQL workflow instance from an information recipient’s perspective:
-- listing the suppliers who shared knowledge with me
SHOW PROVIDERS;
-- view the information shared by supplier acme_provider
SHOW SHARES IN PROVIDER acme_provider;
-- create a catalog from the share
CREATE CATALOG my_catalog USING SHARE `acme_provider`.`first_share`;
-- question the shared knowledge
SELECT * FROM my_catalog.default.first_table;
Sharing Change Knowledge Feed
Delta Sharing now helps sharing Change Knowledge Feed (CDF). Along with sharing a desk, an information supplier can select to incorporate the desk’s CDF, permitting recipients to question adjustments between particular variations or timestamps of the desk. With this function, recipients can question simply the brand new knowledge or the incremental adjustments as a substitute of all the desk every time. A knowledge supplier can simply share a desk with CDF, and an information recipient can question desk adjustments with a easy syntax:
-- knowledge supplier: sharing a desk with CDF enabled
ALTER SHARE my_share ADD my_table AS default.cdf_table WITH CHANGE DATA FEED
-- knowledge recipient: question desk adjustments from variations 5 to 10
SELECT * FROM table_changes('`default`.`cdf_table`', 5, 10)
Enhanced safety features
Within the GA launch of Delta Sharing, now we have additionally a set of safety features to make sharing much more safe. One instance of these safety features is IP Entry Checklist. Knowledge suppliers can now configure an IP entry listing for every of their recipients utilizing open connectors. It ensures that credential obtain and knowledge entry can solely be initiated from the goal IP tackle. We additionally added just a few extra Delta Sharing associated permissions (e.g. CREATE SHARE, CREATE RECIPIENT) and launched proprietor idea for Delta Sharing objects like Share and Recipient. With these primitives, Delta Sharing on Databricks affords a extra versatile entry management mannequin, and non-admin customers also can carry out sharing operations.
