842731 - [meta] Provide a way to transmit large JSON objects across workers without janking

Status: RESOLVED DUPLICATE of bug 873293

(Core :: JavaScript Engine, defect)

In some circumstances, we have to deal with huge JSON objects (up to 50Mb) that we wish to transmit to workers prior to writing them to disk. Unfortunately, that's pretty large and probably not feasible without jank for the time being (no benchmarks so far).

Opening this bug to track ideas on the topic.

A conversation with jorendorff seems to indicate the following avenues:
- provide some mechanism of "prepared statements" that can be used for efficient (de)serialization;
- publish the low-level serialization API to JavaScript.
