Our review
Pros
  • Partitioned wide-column model with CQL query access
  • Datacenter replication and tunable consistency controls
  • Horizontal scaling by adding nodes
  • Apache HBase with ANSI SQL through Apache Phoenix
  • Integrated Apache Solr search with distributed transactions
  • Failover, autoscaling, replication, and enterprise governance
Cons
  • Self-managed deployment requires infrastructure ownership
