Python Generator

Generators are useful when we want to produce a large sequence of values but we don't want to store them in memory at once

yield keyword helps python to execute generator .

Key Features of Generators

Memory Efficient – They do not store all values in memory; instead, they generate values one by one.
Lazy Evaluation – Values are produced only when needed.
Automatic State Retention – The function retains its state between yield calls.
Iterable – Generators can be iterated using a for loop or the next() function.

Implementing Advance Query Optimization in Django ORM

Django's ORM makes database interactions seamless, allowing developers to write queries in Python without raw SQL. However, as applications scale, inefficient queries can slow down performance, leading to high latency and database load. This guide explores advanced query optimization techniques in Django ORM to go beyond basic CRUD (Create, Read, Update, Delete) operations and improve efficiency. 1. Use QuerySet Caching to Avoid Repeated Queries Using cache reduces redundant queries for frequently accessed data. Caching helps reduce repeated database hits. 2. Avoid .count() on Large Datasets Using .count() on large tables can be expensive Inefficient way: Optimized way ( .exists() is Faster) 3. Use Indexes for Faster Lookups Indexes speed up queries on frequently filtered fields. Add db_index=True for frequently queried fields: 4. Optimize Bulk Inserts and Updated Performing operations on multiple records one by one is inefficient. Use bulk_create() for mass insert...

Django Optimization Processes for Write Operation for Postgresql

When optimizing a Django project for large write operations, especially when dealing with PostgreSQL, there are several strategies you can employ to reduce the time it takes to perform these operations: 1. Bulk Inserts In django, we create objects using create() . Asynchronous version is acreate() .It's a convenience method for creating an object and saving it all in one step. and These are same and equivalent. The create() method is used to create and save a single object in the database. Example: Instead of inserting one row at a time, consider using Django's bulk_create() method to insert multiple rows in a single query. This reduces the overhead of multiple database round trips. Example: The bulk_create() method is used to create and save multiple objects in the database in a single query. It accepts a list of model instances and inserts them into the database in a single batch operation, which significantly reduces the overhead compared to individ...

Django: Request/Response Cycle

Django Request Life Cycle A web application or a website revolves around the request-response cycle and Django applications are no exception to this. But it is not just a two step process. Our Django applications needs to go through various stages to return the end user some result. To understand the Django framework better we must understand how the requests are initiated and the end result is served to the end user. When setting up a new Django project, one of the first things you’ll do is wire up your URLconfs and set up some views. But what’s actually happening under the hood here? How does Django route traffic to the view, and what part do middlewares play in this cycle? Layers of Django Application Request Middlewares URL Router(URL Dispatcher) Views Context Processors Template Renderers Response Middlewares Whenever a request comes in first it goes to the web server (Ngnix /Apache) . The the request goes to django's WSGI (Web Server Gateway Interface) / ASGI (Asynchr...
