Python is a versatile programming language allowing efficient and effective coding with various features, including Python Generators. Generators in Python are functions that produce a sequence of results instead of a single value. This sequence of values is lazily created , meaning that the next value is generated only when required…

Python is one of the most well-known programming languages in use today. One of the critical features of Python is that it is an interpreted language. This means an interpreter executes Python code directly instead of compiling source code into machine code. …

In a distributed environment with a central (or leader) server, if the central server dies, the system must quickly find a substitute, otherwise, the system can quickly deteriorate. The scenario in which a distributed system has two or more active leaders is called split-brain. In this article, let’s learn about…

In this article, we will be discussing some helpful resources/tips to optimise the memory usage in python, lets cut through it straight away. Cache it Data-intensive projects can rarely avoid downloading large amounts of data, like website and database dumps, tweets, other social media posts, and the like. These downloads take significant…

From Python Documentation, Pickling is the process whereby a Python object hierarchy is converted into a byte stream, and Un-pickling is the inverse operation, whereby a byte stream (from a binary file or bytes-like object) is converted back into an object hierarchy. Pickling and Un-pickling is alternatively known as “serialization”…

The missing values problem is very common in the real world. For example, suppose you are trying to collect information from a company. There is a field for a company address. Many people want to keep their privacy and leave this field empty. If the data is loaded by pandas…

Spark has become the ubiquitous platform for data processing and has taken over the traditional MapReduce framework. In fact, some technologists would go so far as to declare MapReduce dead. Spark has been proven to outperform MapReduce by several orders of magnitude in numerous benchmarks and performance studies. …

Gossip in distributed systems !?, yes you heard it right, Gossip protocol is a peer-to-peer communication protocol in which nodes periodically exchange state information about themselves and about other nodes they know about. …

Spark SQL allows developers/admins to programmatically issue ANSI SQL:2003–compatible queries on structured data with a schema. Spark SQL was introduced in version 1.3. Since then, several higher-level functionalities have been built upon it Overview of Spark SQL Functionalities Generates optimized query plans and the final execution of compact JVM code. Serves as a bridge to…
