### Layers on top of Storm

#### Trident

Trident is an alternative interface to Storm. It provides exactly-once processing, "transactional" datastore persistence, and a set of common stream analytics operations.

* [Trident Tutorial](Trident-tutorial.html)     -- basic concepts and walkthrough
* [Trident API Overview](Trident-API-Overview.html) -- operations for transforming and orchestrating data
* [Trident State](Trident-state.html)        -- exactly-once processing and fast, persistent aggregation
* [Trident spouts](Trident-spouts.html)       -- transactional and non-transactional data intake
* [Trident RAS API](Trident-RAS-API.html)     -- using the Resource Aware Scheduler with Trident.

#### Streams API

Stream APIs is another alternative interface to Storm. It provides a typed API for expressing streaming computations and supports functional style operations.

NOTE: Streams API is an `experimental` feature, and further works might break backward compatibility.
We're also notifying it via annotating classes with marker interface `@InterfaceStability.Unstable`. 

* [Streams API](Stream-API.html)

#### SQL

The Storm SQL integration allows users to run SQL queries over streaming data in Storm.  

NOTE: Storm SQL is an `experimental` feature, so the internals of Storm SQL and supported features are subject to change. 
But small change will not affect the user experience. We will notify the user when breaking UX change is introduced.
