# Getting Started

The following guide assumes that you are familiar with [Fluent Bit](https://fluentbit.io), if that is not the case we suggest you review the official manual first:

* [Fluent Bit Manual](https://docs.fluentbit.io/manual/)

## Requirements

* [Fluent Bit](https://fluentbit.io) >= v1.1.0 or Fluent Bit from [GIT Master](https://github.com/fluent/fluent-bit)
* Basic understanding of Structured Query Language (SQL)

## Technical Concepts

| Concept | Description                                                                                                                                                                                                                                         |

| Stream  | A Stream represents an unique flow of data being ingested by an Input plugin. By default Streams get a name using the plugin name plus an internal numerical identification, e.g: tail.0 . Stream name can be changed setting the *alias* property. |
| Task    | Stream Processor configuration have the notion of Tasks that represents an execution unit, for short: SQL queries are configured in a Task.                                                                                                         |
| Results | When Stream Processor runs a SQL query, results are generated. These results can be re-ingested back into the main Fluent Bit pipeline or simply redirected to the standard output interfaces for debugging purposes.                               |
| Tag     | Fluent Bit group records and associate a Tag to them. Tags are used to define routing rules or in the case of the stream processor to attach to specific Tag that matches a pattern.                                                                |
| Match   | Matching rule that can use a wildcard to match specific records associated to a Tag.                                                                                                                                                                |
