Hadoop vs. Spark: How are They Different?

Published

Hadoop vs. Spark

As companies come to terms with big data, they have also come to accept that conventional data processing systems simply can’t keep up with its demanding requirements. Big data and AI have come a long way, and it has benefited companies and industries that rely on data to ensure smooth business operations. Without the proper tools, however, data processing and management can be extremely time-consuming and computationally demanding. The way data is used by different organizations depends on a number of contextual factors, since it can be used in a myriad of ways depending on the nature of the business. It also doesn’t end with collecting data, organizations need to find a way to abstract it to a form that can be processed by available data processing frameworks.

The main challenge with big data is the high velocity at which data is generated and its variety; this means that data should be processed quickly while considering the fact that it could include structured, unstructured, and semi-structured data. This is where Apache Hadoop and Apache Spark come in. Through parallel processing and distributed processing, they can help simplify data processing tasks when volume gets too high. Although both parallel processing and distributed processing involve breaking up computing processes into smaller parts, there is an essential difference between them: distributed processing is disk-based and parallel processing is not. Distributed processing “distributes” the workload by using several computers, while parallel processing accesses the same memory space but uses more than one processor.

Hadoop

One of the top big data frameworks still in use today, Hadoop’s reputation as the first ever big data framework ever released precedes the platform itself. It enjoys wide adoption because it has its own ecosystem of tools, the most popular of which, include Hive, Flume, Pig, and HDFS. Considered by many as the simplest of all available frameworks, Hadoop processes data logically. It’s highly fault-tolerant and isn’t dependent on hardware for availability. Designed to detect faults at the application layer, Hadoop replicates data across a computer cluster so it can build the missing parts in case a piece of hardware fails.

Hadoop uses the MapReduce algorithm to split data into blocks that can be assigned to different nodes within a cluster. MapReduce then processes the blocks in parallel so the pieces can be combined into the desired result. Although Hadoop started with MapReduce, it also has the capability to go beyond the algorithm through the use of certain tools, most notable of which, is YARN. YARN is considered the Hadoop ecosystem resource management layer responsible for job scheduling and management of computing resources.

Spark

Spark was created to address the “need for speed” of many organizations. Since Hadoop is disk-based, it performs noticeably slower than Spark, which uses in-memory processing. As such, Hadoop is ideal for batch processing and Spark, for iterative processing. Spark is also designed to address the limitations imposed by the linear data flow of the MapReduce algorithm. This allows for a more flexible pipeline and provides an ideal framework for Spark’s machine learning library, tightly integrated machine learning, MLib, and distributed modeling. Spark can also perform a variety of other big data workloads, including graph computations, interactive queries, and real-time stream processing.

Although some consider Spark as a Hadoop competitor, the two frameworks can actually work to complement each other and replace MapReduce completely. Using Spark in conjunction with Hadoop can free you from the limitations of the aging MapReduce paradigm, allowing you to leverage new technologies to enable faster data processing and filling in the gaps commonly found when working with Spark or Hadoop alone.

Which Big Data Framework is for You?

Hadoop and Spark are two open-source frameworks with key differences. Spark is designed to be fast, uses in-memory processing, and has libraries that can accommodate big data analytics. It doesn’t have a distributed file storage system, however, which Hadoop has. This file system is highly scalable, and needs only the addition of servers and machines to accommodate growing volumes of data and increasing workloads. In the era of big data, the key difference between Hadoop and Spark is in their design. Hadoop is designed for efficient batch processing and is, therefore, a high-latency framework without an interactive mode. On the other hand, Spark is designed to handle real-time data and minimize read/write cycles to disk, increasing overall data processing speeds. Spark is also easier to use than Hadoop because it doesn’t require coding and comes with user-friendly API’s that can be used in Scala, Spark SQL, Java, and Python. Despite Spark’s high data processing speeds, Hadoop still has the upper hand if the resulting dataset is larger than the available RAM. In such cases, the MapReduce algorithm will still outperform Spark.

While choosing the right enterprise database systems can be a challenge and will largely depend on the needs of the business, it’s a choice that has to be made so that the business can take a strategic approach toward data processing and management. Spark may be a newer and more modern solution, but Hadoop remains a relevant and major player when it comes to big data analytics. Ultimately, the decision will boil down to what your business needs are—and what you’re prepared to accept as a computing solution’s shortcomings.

The 6 Biggest Sales Commission Software System Mistakes You Can Easily Avoid

Published

on

Maintaining accurate records of the sales commission structure and distribution is critical to a successful organisation. Using Sales Commission Software guarantees that your records are accurate and can be easily accessed. Sales commission software is a must for any business that pays commissions to employees and independent representatives. Sales Commission Software is a viable alternative to time consuming manual entry and greatly reduces the likelihood of errors in tracking commissions. Using sales commission software you can easily change and adapt your commission structure as your company grows and changes.

The biggest mistakes in commission systems are:

1. Not using Sales Commission Software :

Sales Commission Software allows you to track sales commissions with ease and accuracy. Sales Commission software can also be used to efficiently track and analyze information from sales invoices, purchase orders, orders and more. Your Sales Commission software can save you a lot of time by automating routine tasks and calculations. It can also help you to save costs by eliminating paper-based reporting and follow up.

2. Not compensating sales staff adequately :

Compensate your sales staff sufficiently for their work and time devoted to the organization. Make sure their comp matches up with the number of hours they put in. A good commission plan will be able to motivate your sales staff, but will not allow them to sell more than they could on their own. It is also important that you set a clear policy on what type of customers should be compensated differently and at what level.

3. Using Commissions that are Inadequate or Too High :

Using software sales commissions that are too high can be extremely detrimental to your company. When you have too much money in your compensation pool, it is much easier to create a situation where your revenue will decline and hit the bottom of this pool. In contrast, a commission that’s too low dramatically reduces the total revenue of the company. Using Sales Commission Software will assure you of accurate and easy access to your commission calculations.

4. Not using a commission structure that is easy to understand :

When choosing the right commission system, it is important to know that one size does not fit all. Make sure employees and independent representatives have access to a comprehensive breakdown of the commission structure. Using Sales Commission Software will allow you to modify the commission structure and payout percentages whenever you need. This software will keep your employees and independent reps informed as well as help prevent any misunderstandings and inconsistencies in payouts for sales commissions.

5. Not having a Commission System in Place :

A commission structure is necessary to track sales and ensure equitable pay for your employees. Your commission structure should be set up at the beginning of the year and remain unchanged throughout the year. Once you find a commission system that works for your company, stick with it throughout the year. The best way to ensure that commissions are calculated properly is to have all of your employees use Sales Commission Software. 

6. Not tracking all sales invoices and purchase orders properly :

Sales invoices may include different types of charges on top of the price of goods sold, such as freight charges for shipping goods, costs for supplies used in manufacturing goods, warranty expenses and other labour charges. Depending on the nature of your business, you will have to pay commissions on a variety of charges. This can quickly become a confusing mess if you are not using Sales Commission Software to track sales invoices and purchase orders. 

What is a spiff in sales?

You can understand what is a spiff in sales as it is a small piece of compensation that is given over and above the standard commission rate, usually as a reward for performance or achievement. Spiffs can take many forms and are a significant source of revenue for many salespeople. A good sales commission system should be designed to allow the sales staff to operate effectively.

If you’re having trouble with buffering, try lowering the resolution and make sure that your computer meets the minimum system requirements for streaming. If your computer is outdated, you may not be able to stream or game at optimal quality. 

5. Keep snacks and drinks within reach to avoid interruptions during gameplay or streaming

Anyone who has ever played a video game or streamed a movie or outgoing broadcast knows the importance of having snacks and drinks within reach. Not only does it save you from having to take breaks to prepare food or fetch drinks, but it also helps to prevent you from becoming distracted by your growling stomach. 

Of course, it’s important to choose the right snacks and drinks for gaming or streaming. Something too sugary or caffeinated can lead to an energy crash, while something too salty can make you thirsty. That’s why many gamers and streamers opt for energy bars, nuts, or fruit as their go-to snacks. 

As for drinks, water is always the best choice, but some people prefer to have a can of soda or iced tea on hand for a little boost of energy. Whatever your preference, make sure to keep your snacks and drinks close by so that you can stay focused on your game or broadcast.

6. Create a comfortable environment with proper lighting and noise-cancelling headphones

Whether you’re a professional gamer or just someone who likes to stream their gameplay for fun, it’s important to create a comfortable environment that promotes concentration and immersion. 

One of the most important aspects of creating a comfortable gaming environment is lighting. Avoiding bright overhead lights is key, as they can create glare on your screen and make it difficult to see. Instead, try using a soft lamp that illuminates the area around your screen without being too harsh. 

In addition to lighting, noise-cancelling headphones can also be a great way to improve your gaming experience. With headphones, you won’t have to worry about background noise distracting you from your game or streaming session. 

Plus, if you’re using a microphone to stream, noise-cancelling headphones can help reduce any unwanted background noise for your audience. By taking these simple steps, you can create an environment that’s more conducive to gaming and streaming.

Conclusion

Acrylic Laser Cutter

Acrylic Laser Cutting: What You Need to Know

Acrylic is commonly used for laser cutting. People use it because it is less expensive and reacts well when it comes in contact with the laser. Another amazing benefit of using acrylic is that it offers a flame-polished edge after cutting. The designs you get from acrylic have a fantastic finish compared to any other material. Some people also use these materials due to their availability in different colors and shades. If you need an ideal finish at the end, you can choose the acrylic laser cutting option. Read the article further to learn a few things about acrylic.

Tips for When Use Your Acrylic Laser Cutter

Laser cutting acrylic is a bit different from other materials. It requires more care and expertise. Here are some tips that you need to know.

What thickness do you want to cut?

The laser watt power fitted in the machine will effect the thickness you are able to laser cut. 80 Watt laser tubes are able to cut up to 10mm, 100Watt tubes up to 12mm & 130Watt tubes up to 14mm thick acrylic. If you add a compressor to your laser machines then this will provide you an option of cutting thicker.

Reduce Air Assist

Reducing air assist is important for a fire-polished edge. It can help you get better results. Cutting on the blade table will also help with giving you a cleaning cut.

Focus on the Material

You need to make sure that your material is right in the center of the machine. If your acrylic sheet is not in position, you will not get the right design. Cut on a blade table or raise the acrylic off the honeycomb & laser cut with the plastic cover still on the sheet of acrylic.

You need to remember that not considering these tips can impact your results. Most importantly, your entire design can end up looking unusable. So, make sure that you’re aware of the right methods to use acrylic and machine.

Safety Measures Have in Mind When Laser Cutting Acrylic

Cutting using a laser cutting & engraving machine is a safer method than cutting using more traditional tools like a blade. However, you still need to consider a few safety measures while cutting a material. Before you start cutting the acrylic, ensure that the material is fixed at the center of the machine. This is because the edges coming out of the machine can cause injury. Also, wear gloves when placing acrylic on the machine. Many acrylic materials produce fumes and shards. To avoid getting injured, you need to wear safety glasses.

Frequently Asked Questions

Still, looking for more info? We’ve compiled a list of FAQs – check them out!

Can You Use Acrylic for Every Type of Laser Machine?

No, many laser cutting machines don’t allow you to use acrylic materials such as fiber laser. Fiber laser cutting machines are designed to cut metals only. Therefore, if you need to use acrylic, you should purchase a CO2 laser machine that works best for this material. You can discuss your preferences with the company to make an informed decision.

Is Handling Acrylic Challenging?

Acrylic is easy to handle. In fact, it’s easier to cut acrylic than wood. While it’s true that you might struggle in the beginning, you will learn to do it professionally without too much trouble.
