Technique №1: Compression

The first technique we will cover is compressing the data. Compression here doesn't mean putting the data in a ZIP file; it instead means storing the data in the memory in a compressed format.

In other words, compressing the data is finding a way to represent the data in a different way that will use less memory. There are two types of data compression: lossless compression and lossy one. Both these types only affect the loading of your data and won't cause any changes in the processing section of your code.

Lossless compression

Lossless compression doesn't cause any losses in the data. That is, the original data and the compressed ones are semantically identical. You can perform lossless compression on your data frames in 3 ways:

When we are working on any data science project, one of the essential steps to take is to download some data from an API to the memory so we can process it.

When doing that, there are some problems that we can face; one of these problems is having too much data to process. If the size of our data is larger than the size of our available memory (RAM), we might face some problems in getting the project done.

So, what to do then?

There are different options to solve the problem of big data, small problems. These solutions either cost time or money.

Possible solutions

1. Money-costing solution: One possible solution is to buy a new computer with a more robust CPU and larger RAM that is capable of handling the entire dataset. Or, rent a cloud or a virtual memory and then create some clustering arrangement to handle the workload.
2. Time-costing solution: Your RAM might be too small to handle your data, but often, your hard drive is much larger than your RAM. So, why not just use it? Using the hard drive to deal with your date will make the processing of it much slower because even an SSD hard drive is slower than a RAM.

Now, both those solutions are very valid, that is, if you have the resources to do so. If you have a big budget for your project or the time is not a constraint, then using one of those techniques is the simplest and most straightforward answer.

But,

What if you can't? What if you're working on a budget? What if your data is so big, loading it from the drive will increase your processing time 5X or 6X or even more? Is there a solution to handling big data that doesn't cost money or time?

I am glad you asked — or I asked?.

There are some techniques that you can use to handle big data that don't require spending any money or having to deal with long loading times. This article will cover 3 techniques that you can implement using Pandas to deal with large size datasets.

Clarification:

We are defied with an improvement peculiarity. In spite of the way that
people are on typical living longer, better and all the more wealthy
lives, these advances have not won concerning growing people's sense of safety. This stays steady for countries all around
the world and was getting hold even before the vulnerability
fashioned by the COVID-19 pandemic.
The pandemic has expanded this vulnerability. It has jeopardized each component of our prosperity and intensified a sense
of dread across the globe. This, pair with rising international strains, developing disparities, vote based losing the faith
what's more, crushing environmental change-related climate occasions,
takes steps to switch many years of improvement gains, toss
progress on the Sustainable Development Goals significantly further off course, and postpone the earnest requirement for a greener, more
comprehensive and simply progress.
Against this scenery, I invite the Special Report
on New dangers to human security in the Anthropocene:
Requesting more noteworthy fortitude, created by the United
Countries Development Program (UNDP). The report
makes sense of this mystery, featuring areas of strength for the
between declining levels of trust and expanded sensations of
frailty.
It recommends that during the Anthropocene — a term proposed to portray the period wherein people have become
focal drivers of planetary change, drastically modifying the
earth's biosphere — individuals have valid justification to feel uncertain. Numerous dangers from COVID-19, advanced innovation,
environmental change, and biodiversity misfortune, have become more
noticeable or taken new structures as of late.

2. "I see that you have quite a few papers there. What all do you have in there?" asks Betty Kant, head
of the MIS task force that is the liaison group between your systems group and Sawder's Furniture
Company. You are shuffling a large bundle of papers as you prepare to leave the building.
"Well, I've got some financial statements, production reports from the last six months, and some
performance reports that Sharon gave me that cover goals and work performance over the last six
months," you reply as some of the papers fall to the floor. "Why do you ask?"
Betty takes the papers from you and puts them on the nearest desk. She answers, "Because you
don't need all this junk. You're here to do one thing, and that's talk to us, the users. Bet you can't
read one thing in there that'll make a difference."
a. The only way to convince Betty of the importance of each document is to tell her what you are
looking for in each one. Use a paragraph to explain what each kind of document contributes to
the systems analyst's understanding of the business.
b. While you are speaking with Betty, you realize you actually need other quantitative documents as
well. List any you are missing.

When we are working on any data science project, one of the essential steps to take is to download some data from an API to the memory so we can process it.

When doing that, there are some problems that we can face; one of these problems is having too much data to process. If the size of our data is larger than the size of our available memory (RAM), we might face some problems in getting the project done.

So, what to do then?

There are different options to solve the problem of big data, small problems. These solutions either cost time or money.

Possible solutions

1. Money-costing solution: One possible solution is to buy a new computer with a more robust CPU and larger RAM that is capable of handling the entire dataset. Or, rent a cloud or a virtual memory and then create some clustering arrangement to handle the workload.
2. Time-costing solution: Your RAM might be too small to handle your data, but often, your hard drive is much larger than your RAM. So, why not just use it? Using the hard drive to deal with your date will make the processing of it much slower because even an SSD hard drive is slower than a RAM.

Now, both those solutions are very valid, that is, if you have the resources to do so. If you have a big budget for your project or the time is not a constraint, then using one of those techniques is the simplest and most straightforward answer.

But,

What if you can't? What if you're working on a budget? What if your data is so big, loading it from the drive will increase your processing time 5X or 6X or even more? Is there a solution to handling big data that doesn't cost money or time?

I am glad you asked — or I asked?.

There are some techniques that you can use to handle big data that don't require spending any money or having to deal with long loading times. This article will cover 3 techniques that you can implement using Pandas to deal with large size datasets.

Technique №1: Compression

The first technique we will cover is compressing the data. Compression here doesn't mean putting the data in a ZIP file; it instead means storing the data in the memory in a compressed format.

In other words, compressing the data is finding a way to represent the data in a different way that will use less memory. There are two types of data compression: lossless compression and lossy one. Both these types only affect the loading of your data and won't cause any changes in the processing section of your code.

Lossless compression

Lossless compression doesn't cause any losses in the data. That is, the original data and the compressed ones are semantically identical. You can perform lossless compression on your data frames in 3 ways:

For the remainder of this article, I will use this dataset that contains COVID-19 cases in the united states divided into different counties.

• Load specific columns

The dataset I am using has the following structure:

 

 

import pandas as pd
data = pd.read_csv("https
data.sample(10)ssh u..e@remote_host

 

3.1

./300123456-a3.sh $(pwd)

3.2

if [ $# -eq 0 ]; then
 exit 2
fi

 

3.3

if [ ! -f samplefile ]; then
touch samplefile
fi

3.4

_SFILE=$(readlink -f "$1/samplefile")

3.5

filename=$(echo "$_SFILE" | sed -e "s|^$1/||")

3.6

path=$(echo "$_SFILE" | sed -e "s|/samplefile$||")

3.7

echo "$filename\n$path"
exit 0
 

Explanation:
nl -b a ./300123456-a3.sh

 

300123456-a3.sh:

#!/usr/bin/env sh

if [ $# -eq 0 ]; then
 exit 2
fi

if [ ! -f samplefile ]; then
touch samplefile
fi

_SFILE=$(readlink -f "$1/samplefile")

filename=$(echo "$_SFILE" | sed -e "s|^$1/||")
path=$(echo "$_SFILE" | sed -e "s|/samplefile$||")

echo "$filename\n$path"
exit 0

Clarification:

We are defied with an improvement peculiarity. In spite of the way that
people are on typical living longer, better and all the more wealthy
lives, these advances have not won concerning growing people's sense of safety. This stays steady for countries all around
the world and was getting hold even before the vulnerability
fashioned by the COVID-19 pandemic.
The pandemic has expanded this vulnerability. It has jeopardized each component of our prosperity and intensified a sense
of dread across the globe. This, pair with rising international strains, developing disparities, vote based losing the faith
what's more, crushing environmental change-related climate occasions,
takes steps to switch many years of improvement gains, toss
progress on the Sustainable Development Goals significantly further off course, and postpone the earnest requirement for a greener, more
comprehensive and simply progress.
Against this scenery, I invite the Special Report
on New dangers to human security in the Anthropocene:
Requesting more noteworthy fortitude, created by the United
Countries Development Program (UNDP). The report
makes sense of this mystery, featuring areas of strength for the
between declining levels of trust and expanded sensations of
frailty.
It recommends that during the Anthropocene — a term proposed to portray the period wherein people have become
focal drivers of planetary change, drastically modifying the
earth's biosphere — individuals have valid justification to feel uncertain. Numerous dangers from COVID-19, advanced innovation,
environmental change, and biodiversity misfortune, have become more
noticeable or taken new structures as of late.

2. "I see that you have quite a few papers there. What all do you have in there?" asks Betty Kant, head
of the MIS task force that is the liaison group between your systems group and Sawder's Furniture
Company. You are shuffling a large bundle of papers as you prepare to leave the building.
"Well, I've got some financial statements, production reports from the last six months, and some
performance reports that Sharon gave me that cover goals and work performance over the last six
months," you reply as some of the papers fall to the floor. "Why do you ask?"
Betty takes the papers from you and puts them on the nearest desk. She answers, "Because you
don't need all this junk. You're here to do one thing, and that's talk to us, the users. Bet you can't
read one thing in there that'll make a difference."
a. The only way to convince Betty of the importance of each document is to tell her what you are
looking for in each one. Use a paragraph to explain what each kind of document contributes to
