Well, yeah, it isn't a perfect system, but it is the best option to do it for free. You can use KV/DOs/an external service like Redis, but that would be at cost to you

H

Hello, I’m Allie!•6/11/24, 9:19 AM

And it not being a "general-purpose" cache isn't much of an issue. Open a custom cache that you reserve for D1 Caching, then use bogus URLs

H

Hello, I’m Allie!•6/11/24, 9:20 AM

It won't be cached in more than one datacenter, but it is better than no cache at all

H

Hello, I’m Allie!•6/11/24, 9:24 AM

Though it would be cool to have an arbitrary-object cache that didn't require wrapping stuff in a Request/Response, especially if it could auto-serialize values like DO storage can

H

Hello, I’m Allie!•6/11/24, 9:24 AM

Since that is one thing that you can't do manually unless you bring a serializer yourself(which is kind of heavy-handed)

you could also write an abstraction on top of the cache api so it'd just be

.get(key)

.get(key)

.get(key)

.put(key,value)

Yeah, cost. I'm still being cheap, using the free plan to the extreme

. So in my case using KV is more cost effective than running the query on each request, as I easily cross the threshold for daily rows read by running that one query a few times... but I don't need up to date data all the time. Running it twice a day and otherwise read from KV is the most cost effective solution for me, as it's few reads (a few hundred per day) but lots of rows (1.6M per request).

Hi, I have a very strange behaviour I don't really understand.
When I run a migration adding a column in Table A (by deferring foreign keys ON, creating a new table, copying all data, deleting the old table, renaming the new table to the name of the old table and setting defer foreign keys OFF), all relations of table B to table A (with the id of A in table B) are now

null

null

null

null...
How can I work around this? The migration is generated by Prisma and looks like this:

-- RedefineTables
PRAGMA defer_foreign_keys=ON;
CREATE TABLE "new_Product" (
    "id" TEXT NOT NULL PRIMARY KEY,
    "createdAt" DATETIME NOT NULL DEFAULT CURRENT_TIMESTAMP,
    "updatedAt" DATETIME NOT NULL,
    "name" TEXT NOT NULL,
    "description" TEXT,
    ...some more rows
    CONSTRAINT "Product_eventId_fkey" FOREIGN KEY ("eventId") REFERENCES "Event" ("id") ON DELETE RESTRICT ON UPDATE CASCADE,
    CONSTRAINT "Product_totalCapacityId_fkey" FOREIGN KEY ("totalCapacityId") REFERENCES "Capacity" ("id") ON DELETE SET NULL ON UPDATE CASCADE
);
INSERT INTO "new_Product" ("createdAt", "description", "id", "name", "updatedAt", ...) SELECT "createdAt", "description", "id", "name", "updatedAt", ... FROM "Product";
DROP TABLE "Product";
ALTER TABLE "new_Product" RENAME TO "Product";
PRAGMA foreign_key_check("Product");
PRAGMA defer_foreign_keys=OFF;

);
INSERT INTO "new_Product" ("createdAt", "description", "id", "name", "updatedAt", ...) SELECT "createdAt", "description", "id", "name", "updatedAt", ... FROM "Product";
DROP TABLE "Product";

wrangler d1 execute db-name --command "ALTER TABLE items MODIFY COLUMN user_id INT NOT NULL;"

wrangler d1 execute db-name --command "ALTER TABLE items MODIFY COLUMN user_id INT NOT NULL;"

wrangler d1 execute db-name --command "ALTER TABLE items MODIFY COLUMN user_id INT NOT NULL;"
