# Ingestion

Ingestion is where Pinot tables become real. Start here to choose the right path for batch or stream data, then refine the design with upsert, dedup, file format, filesystem, transform, and aggregation decisions.

The detailed controller and table-config material belongs in [Reference](https://docs.pinot.apache.org/reference/reference). This section stays focused on data flow and operational choices.

## Start Here

* [Batch Ingestion](https://docs.pinot.apache.org/build-with-pinot/ingestion/batch-ingestion) - for data that arrives in files or lands in a warehouse-style batch flow.
* [Stream Ingestion](https://docs.pinot.apache.org/build-with-pinot/ingestion/stream-ingestion) - for Kafka-style or other event streams that should be queryable quickly.
* [Upsert and Dedup](https://docs.pinot.apache.org/build-with-pinot/ingestion/upsert-dedup) - for tables that need one canonical row per key instead of raw event history.
* [Formats and Filesystems](https://docs.pinot.apache.org/build-with-pinot/ingestion/formats-filesystems) - for source formats, file systems, and deep-storage choices.
* [Transformations and Aggregations](https://docs.pinot.apache.org/build-with-pinot/ingestion/transformations-and-aggregations) - for ingest-time cleanup and pre-aggregation decisions.
