Google Play Store To Work On New Algorithm To Halve The Size Of Updates

Worry no more. Google has heard your concerns and rolled out a new Delta algorithm, bsdiff for Google Play Store. “Bsdiff” reduces the app update size and saves on the data required for updating them.

Google Play Store’s new algorithm(bsdiff) does this by compressing the patch sizes for apps and games. Anthony Morris, SWE Google Play, recently said that…..

“For approximately 98 percent of app updates from the Play Store, only changes (deltas) to APK files are downloaded and merged with the existing files, reducing the size of updates. We recently rolled out a delta algorithm, bsdiff, that further reduces patches by up to 50 percent or more compared to the previous algorithm. Bsdiff is specifically targeted to produce more efficient deltas of native libraries by taking advantage of the specific ways in which compiled native code changes between versions. To be most effective, native libraries should be stored uncompressed (compression interferes with delta algorithms).”

Google has also used the new algorithm for APK Expansion Files to allow users to include additional large files of up to 2GB in size within apps. This means that the download size of initial installs will now be lower by about 12 percent, and updates by approximately 65 percent.

Google doesn’t want its users to waste their data unnecessarily for updating their favorite apps. Google has also updated the Play Store descriptions to include the actual download size of the apps. So instead of seeing just the app size earlier on Google Play and remaining in the dark about how much data and storage the update would actually consume, you’ll now get to see the precise size of the app you want to install or update.

Google Play Store updates have started rolling out, don’t be sad if you don’t have this right now. Most of the devices will have this in coming weeks.

Comment below how much you would be saving with this.
