I'm not sure if this is the place to post, but I am not a fan of the front end updates through the dashboard. The fact that I cannot easily see what tables populate the db is very frustrating. Please bring this back. The user interface had a few issues, but this is not better.

GGagan Suie did D1 dashboard just remove "Table" tab? and replace it with "Explore Data"?

I don't have a tab for that, I have to go to the other menu

What do you mean you can’t see which table is populating the database? Do you see the “Explore Data” button on the right side?

A

alphem•6/17/25, 12:57 AM

I see that well enough. My point is that I can't just see everything from the dashboard now. I have to open a new tab in order to see it.

A

alphem•6/17/25, 12:58 AM

It would be best if "explore data" was just a tab on the dashboard.

Hi! I'm looking for some clarity on D1 cold starts. I have a ~600MB database in D1 right now which will mostly be used as a read-only DB, fronted by a Worker-based react-router website. I have not rolled it out into production yet, but the cold starts of ~5 seconds after every 5-10 minutes of idling makes wonder if I made a right choice for a low-traffic use case. I mean, if there is only a couple visitors an hour, they will all get these huge delays on some of the interactions where I very much preferred a 50ms response that's happening after

Are there any rough numbers of when the D1 goes to sleep and how much traffic should be there to avoid cold starts?

K

kd•6/17/25, 9:02 PM

I am querying D1 from separate react-router's "API" routes, which I believe should be bundled altogether in a single worker. The routes that do not touch D1 have like a 50ms ttfb, while routes that query D1 have this super long cold start

K

kd•6/17/25, 9:03 PM

the worst part is that while I was writing this message (~1-2 minutes), it happened again. The subsequent requests are all 40-50 ms though, so I'd assume it's not the heavy joins or something like this (I almost don't have any heavy sql queries)

lambrospetrou•6/17/25, 10:42 PM

The databases go to sleep after 1-2 minutes of inactivity (due to the underlying Durable Object hibernation/eviction).
So, in your case you will experience booting up the database all the time if you query once every 5-10 minutes.

Now, in theory, unless the underlying machine your database is hosted is bad all the time, your boots should be hot after the first one, and startups should be faster without needing to fetch from cold storage all the time. If you share your database ID/account ID I can double check to see the cold starts you were having.

If you mean interleaving JavaScript code and SQL within the same transaction, then not at the moment. You can execute multiple SQL queries in a single transaction using the

batch()

batch()

batch()

batch() function, though, if that fits your use-case.
Otherwise if you need a lot of JS mixed with SQL, using SQLite Durable Objects is more suitable.

Writing to columns referenced in an index will add at least one additional row written to account for updating the index.
