Description: fast random access of gzip files in Python
Drop-in replacement `IndexedGzipFile` for the built-in Python `gzip.GzipFile`
class that does not need to start decompressing from the beginning of the
file when for every `seek()`. It gets around this performance limitation by
building an index, which contains *seek points*, mappings between
corresponding locations in the compressed and uncompressed data streams. Each
seek point is accompanied by a chunk (32KB) of uncompressed data which is
used to initialise the decompression algorithm, allowing to start reading
from any seek point. If the index is built with a seek point spacing of 1MB,
only 512KB (on average) of data have to be decompressed to read from any
location in the file.
.
This package provides the Python 3 module.
