# Pentaho big data overview

Pentaho increases speed-of-thought analysis against even the largest of big data stores by focusing on the features that deliver performance.

* **Instant access**

  Pentaho provides visual tools to make it easy to define the sets of data that are important to you for interactive analysis. These data sets and associated analytics can be easily shared with others, and as new business questions arise, new views of data can be defined for interactive analysis.
* **High performance platform**

  Pentaho is built on a modern, lightweight, high performance platform. This platform fully leverages 64-bit, multi-core processors and large memory spaces to efficiently leverage the power of contemporary hardware.
* **Extreme-scale, in-memory caching**

  Pentaho is unique in leveraging external data grid technologies, such as Infinispan and Memcached to load vast amounts of data into memory so that it is instantly available for speed-of-thought analysis.
* **Federated data integration**

  Data can be extracted from multiple sources, including big data and traditional data stores, integrated together and then flowed directly into reports, without needing an enterprise data warehouse or data mart.

## 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.pentaho.com/install/9.3-install/use-hadoop-with-pentaho/pentaho-big-data-and-hadoop/pentaho-big-data-overview.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.
