This means that it is a bigger responsibility on Riak, Querying by key, or key range (secondary indices are also available), Tunable trade-offs for distribution and replication (N, R, W). Pre- and post-commit hooks in JavaScript or Erlang, for validation and security. Hadoop is probably still the best way to run Map/Reduce jobs on huge datasets. For example: Analysing log data.

DBMS > Microsoft Azure Cosmos DB vs. Microsoft Azure SQL Database System Properties Comparison Microsoft Azure Cosmos DB vs. Microsoft Azure SQL Database. Indexing of nodes and relationships, Advanced path-finding with multiple algorithms and Gremlin traversal language, Advanced monitoring, online backups are commercially licensed, Standalone, or embeddable into Java applications, Full ACID conformity (including durable data), Integrated pattern-matching-based query language ("Cypher"), Also the "Gremlin" graph traversal language can be used, Advanced path-finding with multiple algorithms, Clustering, replication, caching, online backup, advanced monitoring and High Availability are commercially licensed, Very fast (200k+/sec) access of data by key, All nodes are identical (master-master replication), Provides memcached-style in-memory caching buckets, too, Connection proxy for connection pooling and multiplexing (Moxi), In-memory (disk when using Tokyo Cabinet as a backend), Has transactions (an adapted Paxos commit), From CAP, values Consistency over Availability (in case of network partitioning, only the bigger partition works), Cross-datacenter replication is commercially licensed, Uses SSD devices as a block device to store data (RAM + persistence also available), Automatic failover and automatic rebalancing of data when nodes or added or removed from cluster, Has complex data types (lists and maps) as well as simple (integer, string, blob), Data can be set to expire with a time-to-live (TTL), ReQL is functional, if you use Underscore.js it will be quite familiar, Tunable trade-offs for distribution and replication. Real-time data collection. Best used: Or a leaderboard system that depends on many variables. Best used: VoltDB, Any place where scanning huge, two-dimensional join-less tables are a requirement.
