Metrics preview

This is a progress update all about the new metrics dashboard for Trigger.dev.

We're working on two things in parallel to bring the new metrics dashboard together. Firstly, a lot of the current dashboard data is being moved to ClickHouse to allow us to make the dashboard a lot more performant. Secondly, we're building out the new metrics dashboard itself using Recharts.

Here are some details on the interactivity we're building into the new charts:

1. Rather than overlay a tooltip on the chart, we're going to show a fixed number of legend items below the chart with the total values for the whole chart.

2. If you hover over the legend items, we display the totals for that hovered item.

3. If you hover over a single bar, we show just that bar's value in the legend.

4. If you hover over a bar that's hidden from the legend, we temporarily display it as the last entry.

Finally, we've repurposed the Recharts tooltip for some other things…

5. On hover, we show the date in a tooltip and hide all other dates except the first and last to keep the chart clean.

6. You can drag the chart to zoom and the tooltip displays the 'to' and 'from' dates.
