How Python Helps with Big Data Analytics


Processing large datasets can make your computer struggle. Python as one of the best programming languages is designed to help you solve the problem in three main ways. Here’s how Python deals with big data in Python without slowing everything down, thanks to Pandas library support.

1. Optimize Data Types to Reduce Memory Usage

The larger the data the more memory it uses, which means the slower your computer gets. Pandas help reduce memory usage during the process by optimizing data types. When it loads data, it automatically infers data type.

In some cases, specifying the type of data will lead to a significant reduction in memory usage. However, you need to make sure the dataset is not in an exploratory phase.

2. Split Data

Working with big data in Python gets easier as it offers an option to split data into chunk sizes. Most large datasets won’t fit into your memory so you can benefit from Pandas’ split option to break the data into smaller sets. This is much simpler rather than processing one big block.

Furthermore, an iterator object appears when you use this option. Using this object allows you to go through chunks and filter or analyze data just like you would do with the full set.

3. Use Lazy Evaluation

Lazy evaluation means the strategy that delays expression evaluation until the value is needed. Often used in functional programming, lazy evaluation is an important concept because it is the basis where distributed computation frameworks are built.
