Firefox OS/Performance/IndexDB IO Optimization

From MozillaWiki
Jump to: navigation, search


IndexDB is the way apps store/retrieve persistent data on FxOS. Currently IndexDB uses transaction based data write operations. This requires that large chunks of data get broken up into smaller pieces and written separately for better performance. Think of it like scatter/gather I/O. It would be nice to have an "editable" API for data objects so that data can be "streamed" to IndexDB over time in a similar fashion as file handles and fwrite works on most operating systems.
