Datomic. Also interesting: https://github.com/sixthnormal/clj-3df https://github.com/sixthnormal/clj-3df

  Datomic provides a fantastic range of query features, but the underlying Datalog engine does have drawbacks in how it evaluates results eagerly and requires intermediate result sets to fit in memory [0]. For comparison, I work on https://opencrux.com https://opencrux.com which uses lazy Datalog evaluation and can spill to disk when necessary. Naturally there are downsides to this approach also, including a dependence on seek-heavy use of local KV indexes. clj-3df is definitely interesting although not strictly comparable :) [0] https://docs.datomic.com/on-prem/query.html#memory-usage https://docs.datomic.com/on-prem/query.html#memory-usage
