Time Travel and backups · Cloudflare D1 docs

Time Travel is D1’s approach to backups and point-in-time-recovery, and allows you to restore a database to any minute within the last 30 days.

Is there a way to pull backups from the dashboard?

JamesOP•10/6/23, 5:18 PM

No, Time Travel is the only thing available to new databases at this time in that realm of thought. The community solution I linked above is probably what you're looking for if you need a local copy for now.

Thank you, I created a worker that uses the package and am now getting backups to R2 by calling the worker from remote (with auth). Do you know of any commonly used techniques for extending the wrangler CLI so we can add features like this to the runtime and invoke it from the shell/CI?

JamesOP•10/6/23, 6:13 PM

I do not unfortunately. I'd probably just create a

scripts

scripts

folder for myself/team to use these kinds of things, personally. You could probably write something that wraps wrangler, but I don't think the effort would be worth it, personally

EvanPiro•10/6/23, 6:19 PM

How do you go about invoking the worker from local and having it run the backup on remote resources? Also is it possible to pull R2 data from remote to local from wrangler?

JamesOP•10/6/23, 6:20 PM

I don't have this exact use-case, but perhaps you could use

--remote

--remote

? Or put the backup script behind some kind of auth and have a local script hit that?

JamesOP•10/6/23, 6:21 PM

As for R2 data, I don't think there's an easy way to do that with wrangler or similar, no. You would have to use something to download the contents, perhaps via

rclone

rclone

or similar, and then reconstruct the metadata needed locally. You could try asking in #r2 if anyone has any specific recommendations here.

EvanPiro•10/6/23, 6:34 PM

The use-case is replicating some pretty complex state on prod for development on local.

EvanPiro•10/6/23, 6:36 PM

I'm think because I now have a worker that performs the back up, I could also have one that pulls the data and have a script on local which calls both and effectively runs a sync.

Cyb3r-Jak3•10/7/23, 3:26 AM

The 2 GB is per database and the 5 GB is the free quota. So if you have 2x2GB databases then it meets the free plan but you can't have a 3 GB database

dang i’m already at like 100mb in testflight so im worried about 2gb limit. i think i might migrate before launching publicly to save having to migrate later

Adi//•10/7/23, 6:55 AM

I am getting this error while using a complex SQL statement in wrangler D1

"D1_ERROR: A prepared SQL statement must contain only one statement."
Solved: The ;
;
at the end of the SQL statement was breaking it

My statement looks like:

let sql_query = "SELECT *
FROM table_name
WHERE id = ?
  AND timestamp > (
    SELECT MAX(timestamp)
    FROM table_name
  );"

let sql_query = "SELECT *
FROM table_name
WHERE id = ?
  AND timestamp > (
    SELECT MAX(timestamp)
    FROM table_name
  );"

Can I not use combined statements?

Adi//•10/7/23, 7:20 AM

gaah it was just the ";" at the end of the string lol

Also keep in mind that the first 25 billion reads are included in the basic paid plan, so you could refresh the dash 271 million times a month and be OK

MMatt Silverlock Yes, deletes are writes.

Clarification, we aren't transferring any data from mongodb, just migrating the scripts. Is there a way to insert many rows with one API request?

Paul•10/7/23, 1:12 PM

I’m thinking about swapping my Postgres out for D1. Can I still perform large queries across all my users? Any good UI like Dbeaver?

Nikil•10/7/23, 3:09 PM

Why does D1 use SQLite vs Postgres or MySQL? Unless I misunderstood the docs

Nikil•10/7/23, 3:16 PM

Is 2GB per table very much? I've never really built anything at a scale of more than 1k users so I have no idea.

My best comparision metric right now is a CSV that I have with 82 columns and 101k rows listing every single K12 school in america. That CSV is 46MB, and the Google Sheets version is apparently 16MB

All depends how much data you want to save. I have 8 users and around 3GB in the database. It will be higher limit in the future but also already supports alot of DBs so you could setup one per user (soon)

Nikil•10/7/23, 3:32 PM

One per user - that sounds like a crazy pain to keep all of those schemas in sync?

Nikil•10/7/23, 3:35 PM

And it also sounds incredibly un-performant for specific types of queries at least

Nikil•10/7/23, 3:39 PM

Hmm I guess that's a relatively smart way to shard things, especially if a user is almost always in a defined location.

E.g. if I was creating software to manage parking garages or movie theaters, it could make sense to have 1DB per theater, and 1DB for the "central office" objects that might need to be referenced for all of the DBs

But it still sounds crazy and seems like it might increase the total # of writes?

forslunds•10/7/23, 3:41 PM

Or you could just use the DB you think works best for your solution and slap hyperdrive on it?

Nikil•10/7/23, 3:53 PM

If I knew what I was doing, I would agree with this sentiment. But I'm a novice at building product-caliber stuff, so I don't know where to begin other than I want it to be simple to deploy and not eat more than like $10k/yr at scale with a million users in the year.

At smaller scales, I want my whole app to cost < $1/user/mo

Basically, I'm building a course app. We teach high schoolers how to build real products such as Wildfire Simulator in Unity or a Webapp. (I already sell my product to school districts, but am trying to build some in-house custom features and better reporting compared to the third-party tools we're currently using, and then also enable some AI tutoring features in the future).

We host videos, interactive exercises, and quizzes basically. It's kind of like a Masterclass + Brilliant.org

We also have a couple of interesting real-time features such as an office hours queue (so as students are going through one of our projects they can ask a question, and then we group similar questions together and answer the group on a live video call).

Would love to design the system right such that we don't have to completely redo stuff in the near future.
