Since each ingest process talked directly to the Accumulo tablet local to it, it really measured loopback+RPC+DFS performance. Knowing how these things usually go, it might have been 100M rows/s but only 100k-1M RPCs/s. It's still quite impressive, but it's important to keep it in perspective. For example, I believe Google's C* 1M writes/s demo also included real network overhead from driver processes. Additionally, that was with the WAL on, vs. this Accumulo run which disabled the WAL.

Our graph store (HBase, SSD) on 10 nodes can easily support 3M edges/s read/stored, but thats ~40k RPCs/s given our column sizes and average batch size.
