Hi folks, I'd like to share a tip that ~doubled BatchWriter ingest performance in my application.
When inserting multiple entries to the same Accumulo row, put them into the same Mutation object. Add that one large Mutation to a BatchWriter rather than an individual Mutation for each entry. The result reduces the amount of data transferred. The tip seems obvious enough, but hey, I used Accumulo for a couple years without realizing it, so I thought y'all might benefit too. Enjoy! Dylan
