See the FAQ for more information. If you still need to upload the Lightning Design System as a static resource, use the following zip that will meet the static resource requirements.

It is no longer necessary to add a static resource for Lightning Components running within these environments. Please see the Lightning page for more information on extending the template. There are still cases where you will need to use a static resource — specifically, within Visualforce.

In this case, we have provided a tool for you to create your custom-scoped CSS.

In this blog, instead of talking a lot about the web kind of services, we will assume there is a sync client installed in your computer or system and that client is always looking into particular sync folders in which it is always monitoring the changes to the files and uploads it. We will use some cloud storage services like Amazon S3 or any other storage services that keep the file in the cloud.

Ask questions to identify the scope of the system. This will clear the initial doubt and you will get to know what are specific detail the interviewer wants to consider in this service. So start with the core features of dropbox to discuss with the interviewers. If the interviewers want to add some more features such as API integration they will let you know. Suppose you want to share a file that can be of any size small or big and you upload it into the cloud. The reason is… More bandwidth and cloud space utilization: To provide a history of the files you need to keep multiple versions of the files.

This requires more bandwidth and more space in the cloud. Even for the small changes in your file, you will have to back up and transfer the whole file into the cloud again and again which is not a good idea. It will consume more time to upload a single file as a whole even if you make small changes in your file. Discuss The Solution High-Level Solution We can break the files into multiple chunks to overcome the problem we discussed above.

You just need to save the chunk which is updated this will take less memory and time. It will be easier to keep the different versions of the files into various chunks. We have considered one file which is divided into various chunks. If there are multiple files then we need to know which chunks belong to which file. To keep this information we will create one more file named as a metadata file. This file contains the indexes of the chunks chunk names and order information.

You need to mention the hash of the chunks or some reference in this metadata file and you need to sync this file into the cloud. We can download the metadata file from the cloud whenever we want and we can recreate the file using various chunks. We have considered only one client but there can be multiple clients belongs to the same user with the same basic components. The client is actively monitoring the folders for all the updates or changes happening in the files.

To handle file metadata updates e. It also interacts with the remote cloud storage Amazon S3 or any other cloud services to store the actual files and to provide folder synchronization. It gives notification to the indexer and chunker if any action is performed in the files or folders.
