Previously, on Jepsen, we reviewed Elasticsearch’s progress in addressing data-loss bugs during network partitions. Today, we’ll see Aerospike 3.5.4, an “ACID database”, react violently to a basic partition.

[Update, 2018-03-07] See the followup analysis of 3.99.0.3

Aerospike is a high-performance, distributed, schema-less, KV store, often deployed in caching, analytics, or ad tech environments. Its five-dimensional data model is similar to Bigtable or Cassandra: namespaces (databases) contain sets (tables) of records, where keys identify records. Each record is a map of bin names to values. Aerospike has put a good deal of work into performance across good-size (~100TB) datasets, and is repositioning itself as a general purpose datastore competitive with, say, MongoDB.
