Hobbyist here, Is it normal for businesses to be having 50 mil rows to insert into a 50 columns wide database via a 2100+ parameters query, 15000 inserts at a time to a single DB?
Inserting 15k rows of 50 columns into a 50M table is something we do every day.
2100 params on a query sounds like spaghetti code.
I suspect OP is using single row insert statements when they need a bulk insert to be performant.
2100 parameters is a documented ODBC limitation( which applies on all statements in a batch)
This means that a
"insert into (c1, c2) values (?,?), (?,?)..." can only have 2100 bound parameters, and has nothing to do with code, and even less that surrounding code is "spaghetti"
The tables ARE normalised, the fact that there are 50 colums is because underlying market - data calibration functions expects dozens of parameters, and returns back dozens of other results, such as volatility, implied durations, forward duration and more
The amount of immaturity, inexperience, and ignorance coming from 2 people here is astounding
