Kenton Varda (@KentonVarda)

So I've spent the last ~three months writing a new distributed storage engine based on SQLite and it has been FUN!

Advany•5/19/23, 2:23 PM

The new D1 seems really cool!

I have list of jsons (one per host). I need to get it before each worker is run.

The average json is 260 bytes (up to 1 mb).

Currently using redis/upstash for fast global replication and reads.

Looking at the latency of d1. Seems like its only 20ms orso.

Would it make sense to move it? My total database is only 100mb orso.

Any way to know if it's actually working or has quietly failed and is refusing to give up?

Ssourabh.sashank Hey @mozzy did you solved this ?

M

MozzyOP•5/19/23, 2:44 PM

Yes: d1-database

Ssourabh.sashank Didn't got that actually can you please explain ?

Open cmd inside the folder that has sqlite3.exe -> run

sqlite3 file.sqlite3 .dump > db.sql

sqlite3 file.sqlite3 .dump > db.sql

sqlite3 file.sqlite3 .dump > db.sql

Matt Silverlock•5/19/23, 4:14 PM

It's going to really depend on what you're querying and what the shape of the objects you're using is. You also need to take into account the benefits of doing this in your database vs. in your application.
