Eat you greens. Broccoli is good for you. So is Brotli. The compression algorithm update is, as quoted by the RFC7932: "a lossless compressed data format that compresses data using a combination of the LZ77 algorithm and Huffman coding, with efficiency comparable to the best currently available general-purpose compression methods."
In a statement that feels lukewarm in it's strength and defence, Brotli has proven to be more efficient than it's current entrenched competition - gzip - and has what we would regard as decent browser support. But the pastry named performance and compression tool has however not seen the most support from the CDN community. The CDN can been seen as a limiting reagent here: with no support for Brotli, the browser feature is rendered futile.
Inian Parameshwaran discusses the impasse and how he overcame the challenge of employing Brotli at his company. Here are the details.
