Class CompressingStoredFieldsIndexWriter

Efficient index format for block-based Codecs.

this writer generates a file which can be loaded into memory using memory-efficient data structures to quickly locate the block that contains any document.

In order to have a compact in-memory representation, for every block of 1024 chunks, this index computes the average number of bytes per chunk and for every chunk, only stores the difference between

Data is written as follows:
