# Formats and Filesystems

Pinot supports several source formats and deep-storage choices. Pick these early, because they affect how segments are produced, moved, and recovered.

## Source formats

Use the original format docs when you need the exact supported file types or loader behavior. The main landing page is [Supported Data Formats](/build-with-pinot/ingestion/formats-filesystems/pinot-input-formats.md).

## Filesystems and deep storage

Choose the deep-storage backend that matches your operational environment. The detailed filesystem docs still live under [File Systems](/build-with-pinot/ingestion/formats-filesystems/file-systems.md).

## Keep it simple

Do not mix format decisions with schema design. The schema says what the data means; the filesystem says where segments survive after Pinot produces them.

## What this page covered

This page covered how source formats and deep storage fit into the ingestion design.

## Next step

Read [Transformations and Aggregations](/build-with-pinot/ingestion/transformations-and-aggregations.md) if data needs cleanup or pre-aggregation before query time.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## 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.pinot.apache.org/build-with-pinot/ingestion/formats-filesystems.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.
