Stefan Guggisberg commented on OAK-80:
--------------------------------------

FWIW:

> Personally I'd rather see such batching happening under the MicroKernel A=
PI where the implementation actually knows about things like whether networ=
k roundtrips are involved and what kind of batch sizes are most useful.

i imagine that the implementation in the MK would be quite complicated (due=
 to the MVCC contract) whereas supporting batched writes in the upper layer=
 is probably not that difficult.=20

> Currently KernelNodeStore and KernelNodeStateBuilder directly apply every=
 operation on the content tree to the private branch of the Microkernel. Th=
ere have been some concerns re. performance hits due to network latency in =
the case where the Microkernel is not co-located.=20
> I suggest to add batching capabilities such that operations are only writ=
ten through to the Microkernel on certain limits.=20
