Module extensible_array 

Extensible Array chunk index reader. Extensible Array (EA) chunk index reader.

The Extensible Array is used for chunked datasets where the dataspace has a single unlimited dimension. It provides efficient append-oriented storage with O(1) lookup via a pre-balanced hierarchical structure.

Structures:

• EAHD (Extensible Array Header) — configuration + pointer to index block
• EAIB (Extensible Array Index Block) — inline elements + data/super block addresses
• EASB (Extensible Array Super Block) — page bitmaps + data block addresses
• EADB (Extensible Array Data Block) — chunk entries, optionally paged
