If you are the best web scraping expert on Freelancer, we want to hear from you! We need to scrape 2 million products PER HOUR on a leading ecommerce website. As a web scraping expert, you will come up with the best solution for fetching the most recent price/stock changes for 2 million items and allowing our existing software to access your data easily perhaps via a JSON API. The solution you provide should: - Be scalable so that now it will monitor approx 2 million items per hour, but it could grow more in future to 3/4 million maybe. - It MUST be able to scan that many items within 1 hour. So the technology you use must be scalable, e.g. it could use more threads / more proxy addresses etc to scale accordingly. - Your system should also be modular / reusable so that it could be used on OTHER websites such as Costco / Walmart / HomeDepo etc. - Previous experience with this kind of project is desirable. - The solution you come up with should also be cost effective. E.g. some proxy networks we have used in the past charge fees based on bandwidth and since our target website pages are quite large, it is quickly cost ineffective to scrape alot of data every hour, so your solution needs to take into account the bandwidth needs. We are looking to hire an expert ASAP so we look forward to your proposals. Please tell us about any experience and how much time you have available to help with this and similar projects as we also plan to scrape many other stores.

We can reach that speed but we'll need the follwing resources: - at least 25 VPS from vultr or digitalocean - we'll devide the 2 millions products into 25 instances so each VPS will be responsbile of 80 000 products. - unlimited bandwidth proxies (we'll discuss that) The script will be multithreaded to run fastly. all data could be put in a database like MySQL or Mongo (NoSQL) (to be discussed) Please send me a message so that we can discuss all the details.

Hello, My name is Adrian. I represent a software development company and we are looking for a long term relationship with any serious client. We are confident that our qualifications and professionalism will meet your expectations in development of this project and others that may follow. I strongly believe we can give you the scrapping solution that you need. We have an extensive experience in web development in our 11 years on the market. We have worked on different scrapping projects and the most recent one is scrapping for live odds on different markets and providers in the sports betting industry. Everything there is live and we are scrapping it every couple of seconds. It is not a problem to scrap 2m or 4m pages. It all depends on your current infrastructure and proxy deal you have with your providers. It would be good to know your current budget and pricing structure with your current infrastructure to know exactly where we need to optimize. We have an excellent team of programmers, designers and testers. We have the capacity required to provide you with one or more full time programmers that will work on your project until 100% completion. We usually work with a project management system and a bug tracking system an also a SVN. You will be able to see each day's progress on the project not only through our SVN commits but also on our development server. I would like to speak with you live on chat or voice to have all details in place. Regards, Adrian.

Hello. I have developed a lot of similar scrapers to get data from Amazon, Ebay and some other famous websites. They have powerful bot detection algorithms and we have to implement a lot of strategies to bypass the bot detection service. Especially Amazon is very powerful. I have a lot of codes and scrapers and can show you some demos if you are interested. Feel free to let me know your questions. Thanks, Helmot

Hello, I do have the experience you're looking for. I'm going to address each issue, and how I would go about it. First, let's boil the math. 2M in 1 hour means 556 per second. With this amount of requests, the bottleneck will first be with the target server(e.g. Walmart). Just to be clear, most small business websites wouldn't be able to give you a mere 20 per second. The second bottleneck would be with your server and network provider. We're talking 556 threads. Does your service provider allow this? The third and last bottleneck of course is with the proxy service. As you mention, it's better if a small request is used instead of a large one. This will depend on the target website's methods. A site like Warmart will probably have ajax(javascript request) for prices, but maybe not for stock. I don't have to say that this is a lot. If the above conditions can be met, then I can build this for you. Thanks - Custom scripts, solutions, frameworks - Over 50 bots completed(from freelancer and other freelancing sites) - Hosting may be available - HTTP(S) 1.0, 1.1
