An operator is the most basic unit of log processing. Each operator fulfills a single responsibility, such as reading lines from a file, or parsing JSON from a field. Operators are then chained together in a pipeline to achieve a desired result.
For instance, a user may read lines from a file using the file_input operator. From there, the results of this operation may be sent to a regex_parser operator that creates fields based on a regex pattern. And then finally, these results may be sent to a file_output operator that writes each line to a file on disk.
