Accessor
Access the content of bzip2 files.
The bzip2 accessor is able to read the content of bz2 compressed
files. It is very similar to the gzip accessor.
Since bzip2 compressed files do not have an actual file hierarchy,
they can not be directly searched with glob(). This accessor is
therefore only really useful for opening the file for reading - or for
chaining with another accessor.
SELECT read_file(accessor="bzip2", filename="F:/hello.txt.bz2", length=10)
FROM scope()
Performance: Bzip2 files are non-seekable. This means they must be read in sequence from start to finish. If the VQL query attempts to seek within the file, this accessor will automatically decompress the entire file into a temporary file so it can seek within it. This means that performance can be extremely bad in some cases.
