I might be bumping up against some kind of cap with prepared batch statements. Is there a limit to how many you statements you can batch in one call?

M

Murder ChickenOP•5/8/23, 8:13 PM

Definitely possible. It's a lot of inserts.

M

Murder ChickenOP•5/8/23, 8:46 PM

That was it. Batching the batch seemed to get past it.

MMurder Chicken Definitely possible. It's a lot of inserts.

M

Matt Silverlock•5/9/23, 12:11 AM

Curiously: how many? How long (in bytes) is each row/statement, and how big were the batches versions?

M

Murder ChickenOP•5/9/23, 12:23 AM

50k updates. Once I split it into 10k batch batches, it went through.

M

Murder ChickenOP•5/9/23, 12:24 AM

Small updates.

INSERT INTO calendar (c_id, for_date, status) VALUES (?1, ?2, ?3) ON CONFLICT DO UPDATE SET status = excluded.status;'

INSERT INTO calendar (c_id, for_date, status) VALUES (?1, ?2, ?3) ON CONFLICT DO UPDATE SET status = excluded.status;'

INSERT INTO calendar (c_id, for_date, status) VALUES (?1, ?2, ?3) ON CONFLICT DO UPDATE SET status = excluded.status;'

INSERT INTO calendar (c_id, for_date, status) VALUES (?1, ?2, ?3) ON CONFLICT DO UPDATE SET status = excluded.status;'

M

Murder ChickenOP•5/9/23, 12:24 AM

With bind values of integer, date and ~10 character string, so nothing too substantial.

M

Murder ChickenOP•5/9/23, 12:26 AM

So, 50k of basically this:

INSERT INTO calendar (c_id, for_date, status) VALUES ('122393', '2023-04-03', 'AVAILABLE') ON CONFLICT DO UPDATE SET status = excluded.status;

INSERT INTO calendar (c_id, for_date, status) VALUES ('122393', '2023-04-03', 'AVAILABLE') ON CONFLICT DO UPDATE SET status = excluded.status;

INSERT INTO calendar (c_id, for_date, status) VALUES ('122393', '2023-04-03', 'AVAILABLE') ON CONFLICT DO UPDATE SET status = excluded.status;

INSERT INTO calendar (c_id, for_date, status) VALUES ('122393', '2023-04-03', 'AVAILABLE') ON CONFLICT DO UPDATE SET status = excluded.status;

It’s not just the number of rows. How big is each row? What indexes are on the table? The issue is likely materializing the results from disk -> running OOM.

Awesome! Looking forward to seeing how this feature progresses. One question. Is the issue the query / bind payload? If so, for my example, is it possible to use more compact syntax through the native binding functionality? Like this:

INSERT INTO calendar (c_id, for_date, status) 
VALUES 
  (122393 '2023-04-03', 'AVAILABLE'), 
  (122393 '2023-04-04', 'AVAILABLE'), 
  (122393, '2023-04-05', 'AVAILABLE'), 
  ...
ON CONFLICT DO UPDATE SET status = excluded.status;

INSERT INTO calendar (c_id, for_date, status) 
VALUES 
  (122393 '2023-04-03', 'AVAILABLE'), 
  (122393 '2023-04-04', 'AVAILABLE'), 
  (122393, '2023-04-05', 'AVAILABLE'), 
  ...
ON CONFLICT DO UPDATE SET status = excluded.status;

INSERT INTO calendar (c_id, for_date, status) 
VALUES 
  (122393 '2023-04-03', 'AVAILABLE'), 
  (122393 '2023-04-04', 'AVAILABLE'), 
  (122393, '2023-04-05', 'AVAILABLE'), 
  ...
ON CONFLICT DO UPDATE SET status = excluded.status;

INSERT INTO calendar (c_id, for_date, status) 
VALUES 
  (122393 '2023-04-03', 'AVAILABLE'), 
  (122393 '2023-04-04', 'AVAILABLE'), 
  (122393, '2023-04-05', 'AVAILABLE'), 
  ...
ON CONFLICT DO UPDATE SET status = excluded.status;

After reading through the docs, it didn't seem possible to bind an array of objects/data to statement values like this but I may have missed it. This would definitely reduce the payload of larger inserts/updates.

I am using drizzle orm and theoretically the two values should reside in two different keys so they can have the same name. But I don't know the abstraction between drizzle and D1, does d1 always return the joined data as a flat json with only one level of key-value pairs? (in contrast to nested {user: {id: something}} format?
