It could be serialized to an output stream that just counts the bytes. I suppose you could look at the size of the snapshot/journal files to get an estimate. The snapshot files contain the serialized data tree similar to the backup file. The journal contains the rest of the data although it's in some levelDB format but the 2 directory sizes should give a pretty good high-end estimate. > Thanks in advance, > > David Suárez > > _______________________________________________ > controller-dev mailing list > controller-dev@lists.opendaylight.org > https://lists.opendaylight.org/mailman/listinfo/controller-dev > >
