PageDataNode

A leaf page that contains data of one or multiple rows. Format:

• page type: byte (0)
• checksum: short (1-2)
• parent page id (0 for root): int (3-6)
• table id: varInt
• count of all children (-1 if not known): int
• entry count: short
• rightmost child page id: int
• entries (child page id: int, key: varLong)

The key is the largest key of the respective child, meaning key[0] is the largest key of child[0].
