All JSON documents are stored in the array. Every minute the new array is open and the old one is closed. In order to store it efficiently, brotli compression is used. Tests showed that the compression ratio for the 60 points of data is up to 30 and even higher. Most of the modern browsers have the support of brotli encoding out of the box, therefore aggregated data, if requested, is always sent compressed, with Content-Encoding: br. Firefox has brotli compression disabled for non-https connections, but it can be enabled in about:config
