There are several potential issues. One is GC: how convenient is it to
have big datasets subject to GC? Another one is I/O bottleneck: when
adding a file to the store, you currently do an ‘add-to-store’ RPC to
the daemon, pass it the file name, which the daemon then reads entirely
to compute its content hash; could be an issue with big datasets.
HTH,
