  1. Stream Processing

Getting Started

Concept
Description

Stream

A stream is a single flow of data being ingested by an input plugin. By default, each stream name is the name of its input plugin plus a number (for example, tail.0). You can use the alias property to change this name.

Task

A single execution unit. For example, a SQL query.

Results

After a stream processor runs a SQL query, results are generated. You can re-ingest these results back into the main Fluent Bit pipeline or redirect them to the standard output interface for debugging purposes.

Tag

Fluent Bit groups records and assigns tags to them. These tags define routing rules and can be used to apply stream processors to specific tags that match a pattern.

Match

Matching rules can use a wildcard to match specific records associated with a tag.
