since we know that there is no possibility of collision we will straight add it into the DB → high performance, and cache this entry in the cache. so when a request comes it uses one of the numbers from this range and gets converted to the shortURL. Let’s say 1L-2L is one batch and so on.they are unassigned and are free.Īs soon as these services ask for range, counter ranges are assigned to each of the services. out of 3.5 trillion combinations we have to break in some range.
Zookeeper knows okay three AS are online and these servers now ask for the ranges In the memory of ZK we have the range. As soon as added to the system, they will contact the zookeeper and register themselves in the zookeeper.
How do and from where do these servers get to know from where to begin the count and when they will get out of count. In this system, we have added these servers recently. Let’s understand how these app servers get counter reaches?Ĭonsider each and every app server that has a counter running in it.

The only issue we were facing is how to maintain the counter, from where to start the count in case a service goes down. We have already seen how to resolve the collision problem. Technique 3: use counter, it’s thread-safe. What if the long URL is different? we need to change the input and generate the mapping and if not present insert it into the DB. The good thing is there’s always a mapping present in the DB i.e if two users are trying to access the same long URL ‘A’, chances are there that particular mapping is present in the DB and hence no need to insert. Again there are chances of collision in the DB. From the hash code, we use only 7 char and insert them into the DB.

what happens here if we give the same long URL it always gives the same hash code (consists of caps, small letters, and numbers) i.e same short URL.

Now our shorl URL generator is based on M5. Technique 2: Let’s use MD5 to resolve these issues. In RDBMS, we have DB level function like put if not exists which avoid such kind of corruption. One way to resolve that is to have a unique id constraint on a short URL and this way whoever trying to insert last will need to rework their mapping. Both the app server checks if the same short URL exists in DB or not and both of them insert mapping into the table. However both of them got the same random number, as a result, generate same 7 char short URL, i.e we have same short URL for different long URL.

Compressing images with the website is free for everyone and we like to keep it that way! If you like TinyPNG please contribute by making a donation.What if you have two different app servers and at one point in time they convert long URL A and long URL B to a short URL. In 2014 we added intelligent compression for JPEG images and in 2016 we added support for animated PNG. We created TinyPNG in our quest to make our own websites faster and more fun to use with the best compression. Why did you create TinyPNG?Įxcellent question! We frequently use PNG images, but were frustrated with the load times. It allows you to scale, preview and save compressed PNG and JPEG images straight from Photoshop.

You can also install the TinyPNG Photoshop plugin. We’ll convert them to tiny indexed PNG files. You can use Save for Web to export your images as 24-bit transparent PNG files and upload them to TinyPNG. With other versions it is impossible and Photoshop CS5 cannot even display them properly. What about Photoshop?Įxcellent question! Only Photoshop CC 2015 or newer can save images as indexed PNG files with alpha transparency. If you want to create and compress stickers under 500 KB take a look at the iMessage Panda sticker example on Github. Only Internet Explorer does not support the format yet.Īpple added animated stickers to iMessage with the release of iOS 10. Binary transparency without any workarounds! Is it safe to use animated PNG?Įxcellent question! Chrome, Firefox, Safari and now Microsoft Edge all support APNG. With TinyPNG the background becomes transparent again. Still need to support Internet Explorer 6? It normally ignores PNG transparency and displays a solid background color. Is it supported everywhere?Įxcellent question! The files produced by TinyPNG are displayed perfectly on all modern browsers including mobile devices. I have excellent eyesight but can’t spot the difference either! Use the optimized image to save bandwidth and loading time and your website visitors will thank you. In the above image the file size is reduced by more than 70%. The result better PNG files with 100% support for transparency. All unnecessary metadata is stripped too. By reducing the number of colors, 24-bit PNG files can be converted to much smaller 8-bit indexed color images. File size 57 KB vs Shrunk transparent PNGĮxcellent question! When you upload a PNG (Portable Network Graphics) file, similar colors in your image are combined.
