File Systems
This section contains a collection of short guides to show you how to import from a Pinot supported file system.
FileSystem is an abstraction provided by Pinot to access data in distributed file systems (DFS).
Pinot uses distributed file systems for the following purposes:
Batch Ingestion Job - To read the input data (CSV, Avro, Thrift, etc.) and to write generated segments to DFS
Controller - When a segment is uploaded to the controller, the controller saves it in the DFS configured.
Server - When a server(s) is notified of a new segment, the server copies the segment from remote DFS to their local node using the DFS abstraction.

You can also change the filesystem during ingestion. In the ingestion job spec, specify the filesystem with the following config:
