D1's REST API doesn't involve a Worker, which is why it's considerably slower

ah I see the bug, in the console you can

insert licenses (id) values (1);

insert licenses (id) values (1);

insert licenses (id) values (1);

insert licenses (id) values (1); while the dash ui is trying to run this:

{"sql":"INSERT INTO [licenses] (\"id\", \"status\", \"plan\", \"created_at\", \"expires_at\") VALUES ($0,$1,$2,$3,$4)","params":["2",null,null,null,null]}

ilsubyeega•10/11/23, 2:50 PM

will indexing some keys mostly occur that row_read_count being one?
such like

SELECT * from test WHERE id=100

SELECT * from test WHERE id=100

SELECT * from test WHERE id=100

SELECT * from test WHERE id=100 returns

"rows_read": 1

"rows_read": 1

"rows_read": 1

"rows_read": 1 from 150-row table at this moment.

I

ilsubyeega•10/11/23, 2:53 PM

also dunno where to feedback, but just wanting to say maybe adding meta data from query in dash.cloudflare.com would be better (currently doesn't show, needed to open devtools and insepct the response)

K

kian•10/11/23, 3:15 PM

If you prefix your query with

EXPLAIN QUERY PLAN

EXPLAIN QUERY PLAN

EXPLAIN QUERY PLAN

EXPLAIN QUERY PLAN, you'll see that your index on

id

id

results in

SEARCH

SEARCH being used which is only scanning a subset of tables, whereas other keys will show

You'd have to find a tool that can change the MySQL flavour of SQL into SQLite.

If the end of the statement isn't

Is D1 super slow with multiple joins? I have a simple blog schema. I have less than 10k total records. This query executes locally with Sqlite under 200ms but is taking about 7 seconds in production. Is there any way to speed this up or do I need to wait until D1 is more mature for these types of queries?

I executed my schema.sql that was saved locally and contains

CREATE TABLE IF NOT EXISTS Messages (id TEXT, userId TEXT, content TEXT);

CREATE TABLE IF NOT EXISTS Messages (id TEXT, userId TEXT, content TEXT);

CREATE TABLE IF NOT EXISTS Messages (id TEXT, userId TEXT, content TEXT);

CREATE TABLE IF NOT EXISTS Messages (id TEXT, userId TEXT, content TEXT); but when I try to select from Messages it says the table doesn't exist?
