As per the release announcement, Apache Storm has now incorporated some key additional features listed below:
- Secure, Multi-Tenant Deployment which includes:
-- Kerberos Authentication with Automatic Credential Push and Renewal
-- Pluggable Authorization and ACLs
-- Multi-Tenant Scheduling with Per-User isolation and configurable resource limits.
-- User Impersonation
-- SSL Support for Storm UI, Log Viewer, and DRPC (Distributed Remote Procedure Call)
-- Secure integration with other Hadoop Projects (such as ZooKeeper, HDFS, HBase, etc.)
-- User isolation (Storm topologies run as the user who submitted them)
- Foundation for Rolling Upgrades and Continuity of Operations - to ensure upgrade with zero down time
- Easier Deployment and Declarative Topology Wiring with Flux
-- Easily configure and deploy Storm topologies (Both Storm core and Micro-batch API) without embedding configuration in your topology code
-- Support for existing topology code
-- Define Storm Core API (Spouts/Bolts) using a flexible YAML DSL
-- YAML DSL support for most Storm components (storm-kafka, storm-hdfs, storm-hbase, etc.)
-- Convenient support for multi-lang components
-- External property substitution/filtering for easily switching between configurations/environments (similar to Maven-style ${variable.name} substitution)
- Partial Key Groupings - for better utilization of resources when the incoming data is skewed
- Improved Logging Framework - for higher throughput and orders of magnitude lower latency
- Streaming ingest with Apache Hive - that allows data to be written continuously into Hive
- Microsoft Azure Event Hubs Integration
- Redis Support
