Dropbox syncs petabytes of data every day across millions of desktop clients. It is vital that we constantly improve the sync experience for our users, to increase our users’ productivity in their everyday lives. We also constantly strive to better leverage our infrastructure, increasing Dropbox’s operational efficiency. Because the files themselves are being sent to and from Dropbox during sync, we can leverage redundancies and recurring patterns in common file formats to send files more tersely and consequentially improve performance. Modern compression techniques identify and persist these redundancies and patterns using short bit codes, to transfer large files as smaller, losslessly compressed, files. Thus, compressing files before syncing them means less data on the wire (decreased bandwidth usage and latency for the end user!) and storing smaller pieces in the back end (increased storage cost savings!). To enable these advancements, we measured several common lossless compression algorithms on the incoming data stream at Dropbox including 7zip, zstd, zlib, and Brotli, and we chose to use a slightly modified Brotli encoder, we call Broccoli, to compress files before syncing.

Both Smart Sync and selective sync can help you save space. Selective Sync is an older feature that allows you to choose files and folders to sync with Dropbox. Synced files take up hard drive space, and everything you don’t sync can’t be seen or opened on your computer. With Smart Sync, you can choose to make files online-only.

Today, we will dive into the Broccoli encoding, provide an overview of the block sync protocol, and explain how we are using them in conjunction to optimize block data transfers. All together, these improvements have reduced median latencies by more than 30% and decreased data on the wire by the same amount. We will talk about the principles we kept in mind and what we have learned along the way. We will also touch upon how our new investments can help us in the future.
