yes

Aerospike Aggregation Framework is similar to Map/Reduce

yes

could be achieved with distributed queries

Consistency concepts

Methods to ensure consistency in a distributed system

Eventual Consistency in cross-datacenter configuration and Immediate Strong Consistency in local cluster configuration. Also supports single cluster deployments with strong consistency across multiple AZs and Regions.
