Incremental Update 5 at Feldera

We’re excited to announce the release of v0.25, packed with new features, improvements, and the usual round of bug fixes.

Webconsole Enhancements

We’ve reintroduced the throughput and memory graphs to the Webconsole. Initially removed due to not being ready in the new UI, these graphs are now back, providing essential insights. Additionally, we tackled an issue where the Webconsole would become unresponsive under heavy load, specifically when the pipeline sent a massive number of changes to the Changestream.

New Google Pub/Sub Source Connector

We’ve added a new source connector for Google Pub/Sub, allowing you to stream changes from a SQL table via a Pub/Sub subscription in Google Cloud.

Compiler Fixes and SQL Improvements

On the compiler side, we resolved a bug involving multiple LAG statements that could produce incorrect results, along with a watermark bug that could trigger a pipeline panic. We’ve also enhanced the ergonomics of SQL code that utilizes NOW(), and added support for temporal filters. Previously, NOW values had to be managed in a system table, but with this release, that’s no longer necessary. For more details, check out our updated documentation..

New CLI Tool: fda

We’re also introducing fda, a new CLI tool designed for interacting with the Feldera API directly from the command line. This is an early-stage tool, so give it a spin and let us know how we can make it better. More details are available in the documentation.

Here’s a screenshot showcasing the revamped throughput and memory graphs in the Webconsole, along with an example SQL program utilizing NOW() and a temporal filter:
