“In hundreds of tests of SC mode through network partitions, 3.99.1.5 and higher versions have not shown any sign of nonlinearizable histories, lost increments to counters, or lost updates to sets.”
– Kyle Kingsbury, Aerospike 3.99.0.3, 12-27-2017
We believe Jepsen has validated our core claims: within reasonable operational constraints, Aerospike does not lose data, nor does it allow stale or dirty reads even with high concurrency, challenging network conditions, and crashes. In order to test these claims, Kyle ran existing Jepsen tests, but also a variety of new custom-crafted “nemeses”. Kyle also improved Jepsen with a higher performance core engine, as well as fixed Jepsen internal bugs.
