Python Quiz: What is the output of the following Python code?

@SumitM_X Because DB uses account_id index to fetch rows, then still sorts by trade_time. Separate indexes cannot be combined well, so extra sorting or temp table happens. Composite index (account_id, trade_time) fixes it by returning already ordered data.

This query is running slow: SELECT * FROM trades WHERE account_id = 1021 ORDER BY trade_time; Index exists on account_id Index exists on trade_time Why is this still slow ?

Hi guys 👋 I’m a Full stack developer passionate about building web and mobile apps. If you’re in tech, let’s connect !

@SumitM_X Partitioning by time may not help because the query filters by chat_id, not by date. I’d first add or check a composite index like (chat_id, created_at) so the database can quickly find and sort messages for one chat.

Tech Lead sees most queries look like this: SELECT * FROM messages WHERE chat_id = 874234 ORDER BY created_at And THE TECH LEAD sys: "Lets partition messages table by time." What's your reply?

@ayesha_fatiima A library is a tool you call when you need it, but a framework controls the app flow and calls your code itself. In short: with a library you stay in control, with a framework the framework is in control.

As a Developer, do you know the difference between: - Library - Framework

@devXritesh First, I check indexes and the query execution plan. In staging, small data can hide performance problems, but in production the database may scan millions of rows because of missing indexes or inefficient joins.

As a developer, Your SQL query works in staging… but becomes painfully slow in production after data grows 100x. What’s the first thing you check?
