Detailed Description

Thrift-derived struct describing the page header.

Column data are divided into individual chunks, which are subdivided into pages. Each page has an associated header, describing the page type. There can be multiple page types interleaved in a column chunk, and each page is individually compressed and encoded. Any missing or corrupted pages can be skipped during reading.
