maximum recursion depth exceeded

See original GitHub issue

I’m trying to find a way to add bulks of items into the db (something like the COPY postgres https://www.postgresql.org/docs/current/sql-copy.html would be perfect).

When I add 3 items, it works. When I add 100 it fails. When I add 1000, it fails… with a slightly different error message! (InternalServerError: maximum recursion depth exceeded). The while calling a Python object part is missing.

Thanks @elprans !

It took 56 seconds to insert 73,247 records. Using containers. I’ll do more tests tomorrow 😃.

Time to sleep (past 5am, in HK) thanks for your support!

Ah, right. Tuples as arguments are currently unsupported (this is a Postgres restriction really). So, one way to implement this is to use JSON as input instead:

WITH idx1 := (SELECT Index FILTER Index.name = 'idx1'),
FOR x IN {json_array_unpack(<json>$json_array)}
UNION (
UNION (INSERT History {
    index := idx1,
    timestamp := <datetime>x[0],
    value := <float64>x[1]
});

Where $json_array is the result of json.dumps(). In this scenario you need to make sure your datetime data is a proper ISO-formatted string that includes the timezone.
