Using batches or transactions?

[sannegrinovero]

Hi,
using some other technique I'm already guaranteeing that no other node will apply changes to my distributed map.
Given this knowledge and wanting to put several values on different keys, and do some reads too in the mix, should I use transactions or startBatch()?
Are the changes pushed to the map visible to the local node even before endBatch()?

The purpose of the batching API is to combine various updates into a single RPC message, for efficiency's sake. For real isolation and atomicity, you should use transactions.
