Hi,

implementing the transient space in Oak-Core is legitimate, although premature optimization for the specific use case where the entire stack (jcr-...-mk) runs in the same vm.
To clarify, the decision to write changes from oak-jcr directly to oak-core was not driven by performance ("premature optimization") but rather by the need a) to in any case have those changes in oak-core for validation, etc. and c) to support large content imports that wouldn't necessarily fit into memory. We also wanted to avoid having to write essentially the same code twice for oak-core and oak-jcr. The performance benefit of reduced amount of internal copying and memory overhead is just a nice side-effect of the design.
See the mentioned list archives of March/April for more background, with [1], [2] and [3] being good starting points.
