The Markdown source in this directory is published as part of the Apache Cloudberry website at https://cloudberry.apache.org/docs. The site build is owned by apache/cloudberry-site (Docusaurus-based); this repository keeps the source-of-truth Markdown so documentation can be edited alongside the PXF code it describes.

• Files use plain Markdown with Docusaurus-flavoured frontmatter:

  ---
  title: Reading and Writing HDFS Parquet Data
  description: Read and write Parquet data in HDFS via PXF.
  sidebar_position: 6
  ---

• Internal links use relative .md paths (for example, ./hdfs_text.md or ../administering/cfg_server.md#about-the-pxffsbasepath-property). Heading anchors are auto-generated by Docusaurus from the heading text.

• Images live under graphics/ and are referenced with relative paths (for example, ../graphics/pxfarch.png).

• The directory layout mirrors the website sidebar. Each sub-directory carries a _category_.json describing its label and position; new categories should follow the same pattern.

Clone apache/cloudberry-site, point its sync script at this checkout, and run npm start. See the cloudberry-site repository for details.
