# Redis-Caching

Standardmäßig verwendet ngSurvey bei aktivierter verteilten Cache-Funktion seine Datenbank zur Verwaltung der zwischengespeicherten Objekte. Als Alternative für hochleistungsfähige Szenarien ist es auch möglich, stattdessen einen Redis-Caching-Server für ngSurvey zu konfigurieren. Diese Konfiguration kann die Leistung verbessern, indem sie die Cache-Speicherung von Ihrer Datenbank auf den Redis-Server verlagert.

Um Ihren Redis-Caching-Server einzurichten, legen Sie die folgende Umgebungsvariable mit Ihrer Redis-Verbindungszeichenfolge fest; optional können Sie auch einen spezifischen Instanznamen für Ihren Redis-Speicher angeben.

```
NGSurvey:RedisConnectionString
NGSurvey:RedisInstanceName
```

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

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.ngsurvey.com/de/installation-setup/installation/cluster-scale-out-configuration/redis-caching.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

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.
