New Feature: Dataflow JDBC/ODBC Connector

Today we’re excited to announce the general availability of our JDBC/ODBC Dataflow connector. This feature leverages the same intelligent persistence layer that backs Queryable Dataflows and Structured Data Lakes, and joins it (pun intended) with the SparkSQL Thrift JDBC/ODBC Server to provide the ability to directly access and query your Dataflows from your favorite environment, whether it is a BI tool like Looker, or your favorite SQL workbench.

New Feature: Scala & Java Transforms

Today we’re excited to formally announce support for Scala & Java transforms. Not only does this expand our support to two of the most popular languages amongst data engineers, but marries this capability with the advanced orchestration and optimizations provided by Ascend.

New Feature: Credentials Vault

With a strong emphasis on data security and compliance, Ascend employs a flexible, role-based permission model, ensuring only authorized users have access to sensitive secrets and data. As our customers build and evolve their Dataflows, several patterns have emerged:...

New Feature: Recursive Transforms

At Ascend we see all sorts of different pipelines. One pattern we see quite often is that of change data capture (“CDC”) from databases and data warehouses, followed by data set reconstitution. Doing this data set reconstitution usually requires a full reduction — a transform in which you iterate over all records to find those representative of the latest state. This can become inefficient over time, however, as greater and greater percentages of any given data set become “stale”.

Data Lake ETL Tutorial: Transforming Data

Now that you’ve learned to Extract data with Ascend, this tutorial will give you an overview of the “T” in ETL, namely, how to start transforming your data before you load it into the final destination. We will use SQL in this example, but Ascend also supports...
