# Global Settings

Globals allow defining and loading properties which are not tied to a specific system component to runners (e.g. to application.properties files). Typical use cases include:

* **Serde Configurations:** Defining serialization/deserialization settings for different runner types, used across all streams (e.g. task.drop.serialization.errors setting for Samza runners).
* **Runner Specific Configurations:** Core Spring, Samza, etc. properties to apply (e.g. job.coordinator.system for Samza runners).

These settings are typically defined only once at the initial Rierino platform deployment (with predefined values) and do not change over time. The main benefit of these elements is to provide complete control over underlying system library settings.

For more details on available generic settings, please refer to your selected runner's own documentation (e.g. Spring, Samza).

Since they are runner specific, global settings usually have their runner type defined.

An example is "task.ignored.exceptions" configuration for [Samza](https://samza.apache.org/learn/documentation/latest/jobs/configuration-table.html), which specifies list of exceptions to ignore in a task's process or window methods.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.rierino.com/devops/microservices/building-blocks/additional-elements/global-settings.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
