Linked Tables and Charts
Since our last blogged release our biggest new feature is Linked Tables and Charts.
When a user clicks on a table or chart, it populates variables that can be used within other charts and tables.
One very creative user already used this to create tableA that when clicked populates tableB, that when click populates tableC and so on 4 levels deep.

Stability
With increasing users comes more edge cases that are hard to predict in advance. We’ve invested a lot in stability in the last 2 months, not all of which will be immediately visible. One hotspot involved a number of issues related to websockets including internal firewall rules, cloudflare websocket timeouts and slow subscribers. One of the more interesting changes was introducing a heartbeat on the websocket to prevent timeouts, we then reused that heartbeat to detect slow subscribers for example when someone moves a tab to the background or minimizes their browser. We now smartly throttle back their querying until they catch up or bring the browser back to being visibile. We’ve addressed all known issues and added a number of stress testing test runs to ensure they always continue to work in future.
REST API
Lastly, some of our advanced kdb users spin up dynamic processes for users. They wanted to make those servers available in Pulse.
We’ve added a REST API to allow setting servers dynamically using a API keys.

0.6.5 release in July 2022
For our initial release of Pulse we had 4 essential use cases that we solved. This included:
- Trade Blotter – Scrolling real-time table of trades.
- TAQ – Trade and Quote graph of teal-time quotes
- A live updating current price table with color highlighting.
- A simple time-series graph to plot single metrics. e.g. mid price over time.
1.0 Release March 2023
Pulse is a tool for real-time interactive dashboards.
Over the last few months we focussed on adding new visualizations , allowing charts/tables to be customized and supporting QuestDB.
The goal for 1.0 is:
- Increased Interactivity – To allow user interaction
- Support for large deployments
- Dynamically updating data sources – For when db server deployments can change host/port
- Licensing – builtin
- Reporting tools – to show current and historical dashboard usage
- Possible custom connection to user to allow security.
- Stability
- Warn when dashboard is growing very large
- websocket heartbeat to prevent idle disconnects
- Improved User Friendliness
NOT in 1.0 but still on the long term roadmap is grid UI improvements , scripting and further expanding data sources.

We’ve added a new tutorial and demo, creating a crytpo dashboard with QuestDB backend:
Pulse – Real-time interactive Dashboards 0.14.1 adds a Metrics Panel.
Allows tracking headline text while still showing the trend as a background chart.
