Github Stars Shooting Up

Admittedly we weren’t trying to get github attnetion for the first 10 years so it’s a low start but we’ve made good progress.

Version 3.0 with Notebooks Launched in October

It looks like a quick holiday from coding in August, then coming back with fresh ideas and heads-down in October to get Notebooks released.

Downloads Grown Steadily Every Month

In case you are wondering the 1 fortnight where data is off the chart was this hacker news post.

We used https://notes.cleve.ai/unwrapped to generate this calendar of our major linkedin posts:

The Best SQL Notebooks

Want to create beautiful live updating SQL notebooks?
While being able to easily source control the code?
and take static snapshots to share with colleagues that don’t have database access?

Today we launched exactly what you need and it’s available in both:

• QStudio Version 4 – Desktop SQL Client entirely based on editing markdown files locally.
• Pulse Version 3 – As a shared team server, where users only need a web address to get started and share results.

SQL Notebook Examples

We have worked with leading members of the community to create a showcase of examples.
These are snapshotted versions with static data. The source markdown and most the data to recreate them are available on github.

Let us know what you think, please report any issues, feature suggestions or bugs on our github QStudio issue or Pulse issue tracker.

Thanks to everyone that made this possible. Particularly Brian Luft, Rich Brown, Javier Ramirez, Alexander Unterrainer, Mark Street, James Galligan, Sean Keevey, Kevin Smyth, KX, Nick Psaris and QuestDB.

SQL+Markdown qStudio Experiment 2024

Pulse News – April 2024

It’s approaching 2 years since we launched Pulse and it’s a privilege to continue to listen to users and improve the tool to deliver more for them. A massive thanks to everyone that has joined us on the journey. This includes our free users, who have provided a huge amount of feedback. We are commited to maintaining a free version forever.

We want to keep moving at speed to enable you to build the best data applications.
Below are some features we have added recently.

Pivot Like a Pro

Pulse enables authors to simply write a select query, then choose columns for group-by, pivot and aggregation. Users can then change the pivoted columns to get different views of the data. The really technical cool part is:

• Unlike other platforms, Pulse does not attempt to pull back all data.
• All aggregation of data is performed on the SQL server, making it really fast.
• For kdb+, aggregation and pivoting occur on the kdb+ end using the common piv function.

Caching for Faster Results and Less load

• As we have deployed Pulse at larger firms with more users, the backend databases began to become a bottleneck.
• Polling queries to data sources can now be cached and results reused within the time intervals selected.
• This means whether there are 1, 10 or 100 users looking at the same dashboard with the same variables, it will only query once, not separately for every user.

What Changed? Diff.

• Pulse has allowed users to open or restore previous versions since version 1.
• Now you can view a diff to see which code or query changed.
• Next we want to add support for file/git based deployment.
• If this is something that interests you, add a note to the issue.

Tabs and Sheets
Pulse now supports both a tabbed interface and top level sheets.

New SQL Docs

We just launched a new sql documentation website: sqldock.com
to allow integration with Pulse / qStudio and docs more easily.
More updates on this integration will be announced shortly. 🙂

Pulse 2.0 Feature Sneak Peak – Markers

We have been working on version 2.0 of Pulse with a select group of advance users for weeks now. To give you a preview of one new feature, check out markers shown on the chart below. We have marker points, lines and areas.For example this will allow adding a news event to a line showing a stock price. This together with many other changes should be released soon as part of 2.0.
