indexed-zstd 1.2.2

Fast random access to zstd files

indexed_zstd

This module provides an IndexedZstdFile class, which can be used to seek inside zstd files without having to decompress them first.

It's shamelessy based on indexed_bzip2, which was refactored to support zstd instead of bzip2 using libzstd-seek.

Kudos to the author for its work.

Seeking inside a block is only emulated, so IndexedZstdFile will only speed up seeking when there are more than one block, which sadly requires a bit of care in zstd.

Usage

Example 1

from indexed_zstd import IndexedZstdFile

file = IndexedZstdFile( "example.zst" )

# You can now use it like a normal file
file.seek( 123 )
data = file.read( 100 )
